Pala’s Featured Specimens: Aquamarine from Pakistan
and Kunzite from Afghanistan

This month we feature a pair from Pakistan and Afghanistan. From the western front of the Himalaya Mountains we find a couple of exquisite crystals still carrying a chunk from the host rock.

Aquamarine Specimen photo image
Etched aquamarine, 12 x 10.5 x 10 cm. Price available upon request. (Photo: Mia Dixon)

This aquamarine is like a prismatic glacier poised in a bed of cleavelandite and accompanied by a quartz point. There are a of couple traces of pink apatite and possibly tantalite on the specimen as well. This aquamarine exsolved from its original form to its current etched shape, leaving a pastel-blue, gemmy, ice-like sculpture. This oddity comes to us from Shigar Valley, Pakistan.

Kunzite Specimen photo image
Kunzite in matrix, 7.3 x 5.5 x 7.4 cm. Price available upon request. (Photo: Jeff Scovil)

Just across the border, in Afghanistan, we find this classic pink prismatic kunzite crystal still wrapped in the pegmatite host. It’s a classic lilac kunzite blade over 7 cm and very gemmy. It is quite a rare find to see kunzite still attached to the matrix; almost all of the specimens seem to be loose single crystals. A choice specimen for gem crystal collectors, from the Pech, Konar Province, Afghanistan.

Ruby for Tourmaline: Blue-cap’s 40th

Minerals cover image

This year is the 40th anniversary of what one museum curator called “the find of the century.” In early 1972, history was made in northern San Diego County with a stunning find of “blue-cap” tourmaline specimens that would go by the now-familiar names of “Candelabra,” “The Rabbit’s Ears” and more.

That year, following world-class specimen after museum-quality specimen being eased from the clay of the Tourmaline Queen Mine, Pala International’s Bill Larson penned a piece on the discovery for Lapidary Journal. The article has been reprinted in the current edition of Minerals: The Collector’s Newspaper, published by Poland’s Geological Society “Spirifer.” The article is richly illustrated with on-site and studio photographs, some of which have never been published.

Accompanying Bill’s article is a profile of the Tourmaline Queen by Spirifer’s Tomasz Praszkier. The text and accompanying photographs take you through the years at the mine, which turns 110 in March. While the mine is no longer active, it has produced lifetimes of treasures.

Ruby (hint, hint) is the traditional 40th anniversary gift. [back to top]

Glass Act – Part Two

Gemstone models and specimens from Czechoslovakia

Crystal Models photo image

In our sibling e-newsletter last month we featured a collection of hand-cut glass crystal models, pictureed at right, acquired by Pala International’s Bill Larson this year at the Denver show. The set of models now has a place in the Virtual Museum of the History of Mineralogy.

Bill brought out three more collections, which we share here. We begin with a set of 72 glass models of faceted and cabochon gemstones from the early 20th century.

In 1907, George Gibbs, above, published his novel The Medusa Emerald. His illustrations appeared in many magazines as well as his own books. Today we have the opportunity to see the real Medusa Emerald on display at London’s Natural History Museum. This unique specimen is being presented in the museum’s Green Zone exhibition area known as The Vault. The specimen was mined in Zambia in 2008 and sent to The Collector’s Edge in Colorado to be cleaned of its quartz matrix.

The Medusa began its one-year exhibition on July 20. Also in The Vault are:

  • The Devonshire Emerald, at 1,383.93 carats, one of the largest uncut emeralds in the world
  • The Tissint Martian meteorite, which fell near the Moroccan village of Tissint in the summer of 2011
  • The Esquel pallasite, a meteorite embedded with gem-quality olivine crystals, found in 1951 in Argentina
  • The rare Dar Al Gani meteorite, from the Moon, found in 1998 in Libya

Good as Gold: A Love of Labels

When we visited Elise Skalwold at Cornell in October, she told us a story (recounted below) that will appeal to anyone who ever has visited the archives of higher learning and other institutions. Yes, typewritten correspondence is great for the information it contains, even an email printout, but there’s nothing like handwriting to connect us with the character of our subjects.

In 2009 someone handed me a little bottle of diamond crystals with an old curled label—the diamonds were not necessarily significant in themselves, very, very tiny and various colors—you can see them here. (Antoinette Matlins used the top photo in the latest edition of her diamond book.)

I like old documents, especially handwriting, as you know. I think without that first label I might not have pursued what has become a big project for me: often when an institution accepts a collection, old labels are discarded (or maybe filed and then someone in the future throws the file out...in this case sometime in 125 years).

Everyone said I would never find the original Silliman labels which accompanied a diverse mineral collection Cornell acquired in the 1870s from Silliman who was then at Yale. I took the diamond photo in 2009, sporadically searched for records, labels, any documentation; this past summer I found a stash of dozens of labels hidden under a shelf. In the meantime, I’ve been researching Benjamin Silliman Jr. and have uncovered a “colorful” person.

Gold Specimen and Label photo images
Good as gold. Above, pairing of a label with its gold specimen, 2 cm high on a quartz matrix. Below, a label Elise thought showed that Silliman would be quite happy hawking specimens on eBay. Both labels date from the 1860s. (Photos: Elise Skalwold)

And Amethyst…

In October, in our sibling publication, Elise reviewed a monograph on amethyst, isssued by Lithographie.

No. 16 in Lithographie’s monograph series is so visually luscious one’s mouth actually begins to water as page after page of exquisite purple-hued imagery greets the eye. This long anticipated volume brings together a diverse group of authors and photographers whose passion for this most highly-prized variety of quartz is self-evident in each of their contributions.

Pala Presents

The Pegmatyte Veins of Pala, San Diego County

By G. A. Waring

Pala Presents title image

With Pala Presents, we offer selections from the library of Pala International’s Bill Larson, who will share with us some of the wealth of information in the realm of minerals and mineralogy.

At the beginning of “The Pegmatyte Veins of Pala,” our current Pala Presents offering, G. A. Waring quotes H. W. Fairbanks regarding the “simple” geological structure of San Diego County: desert on the east, mesa on the west, and the “range of crystalline rocks in the middle.”

It is these crystals, found in pockets and veins as Waring describes, that continue to thrill miners, dealers, and collectors 107 years after Waring’s study was published in The American Geologist.

Below are four recent items from our sibling publication, Palagems Reflective Index, will be of interest to mineralophiles.

Mad for Munich

Pala International loves to have had the opportunity over the last two years to have floor space at the Munich Show. This year, Pala also contributed to the show’s themed exhibition, “African Secrets.” Several Pala people were caught in the camera lens of fellow Southern Californians Eloïse Gaillou and Alyssa Morgan, members of the Mineral Sciences staff of the Natural History Museum of Los Angeles County, who attended the show. Behind-the-scenes shots and more are included in Gaillou’s Minblog post.

The photos below are included, with ten more, in “Munich 2012” on Palagems.com.

Jade Mask photo image
“He what?!” Bill Larson, reacting to news that Christophe dropped “The Snail.” (Photo: Bill Larson)

Will Larson was quoted in Süddeutsche Zeitung, Germany’s most popular national daily newspaper. We provide a rough translation of a excerpt below.

The darling of German windowsills, “The Snail” is an approximately fist-sized rhodochrosite, shaped like a black worm with a red “house.” “I like the shape,” says Will Larson, a young man dressed in a purple shirt, and as he says it, he shows almost childlike enthusiasm. Will’s father [Bill] said the specimen was discovered* from the South Africa N’Chwaning mine during manganese removal. The Austrian dealer and collector Rudolf Watzl estimates the value of the specimen at about ten million euros. [Implying that it is invaluable,] he says, “This is your possession, but not with money to offset,” looking longingly at the glittering red. These minerals show that, in the Larson home, value is put into curious shapes, such as Will’s “Mickey Mouse” and “deadmau5,” precious stones in orange [olmiite] and green [prehnite], which strikingly resemble their namesakes.

“The value of the pieces is not calculated in price,” says Will Larson, who works day-in-day-out with mineral specimens: “It is the love of their beauty.” And that is there to be seen—if the grandeur of the stones is reflected in the eyes of the beholder.
_______________
*The German-language version of the article states, inaccurately, that “The Snail” had been “smuggled” (geschmuggelt) from the mine.

Gems & Gemology Features Pala Pieces

Gems & Gemology cover image

Pala International is cover star of the current Gems & Gemology journal, issued last month by GIA. The specimen and stones, photographed by Robert Weldon, herald the featured article, “Gemstones from Vietnam: An Update,” by Dr. Le Thi-Thu Huong and a team of coauthors. The article discusses the country’s major gemstones, highlighting recent production and new finds. New information is included on the gemological properties and chemical composition of ruby, sapphire, spinel, tourmaline, garnet and peridot from the major localities. Other stones also are reviewed.

The luscious jumble of a ruby specimen pictured above is from Luc Yen, in northeastern Vietnam. It’s in the collection of Bill Larson. Luc Yen produces a host of gemstones and minerals, as listed in this Mindat entry.

The three faceted gemstones, from Pala International, also hail from northern Vietnam. Left to right, they are a 1.97-carat blue spinel, a 5.07-carat red spinel, and a 2.27-carat ruby.

About that ruby specimen…

Will Larson shares a remarkable memory regarding acquisition of the specimen.

When I was 12 years old my father took me on a Southeast Asia tour visiting Burma, Thailand and Vietnam. Vietnam was our last stop and was an amazing experience. I remember flying into Hanoi, and my father pointed out the Russian-made planes, which looked rusty and old. He said we will not fly on those because of safety issues, and sure enough a few days later one crashed trying to land at Siem Reap Airport in Cambodia. After clearing customs we arrived at the house of my father’s contact, Sun Ta. The architecture is different, as they are very narrow but tall, three-story homes. What I probably remember most was that Sun Ta had a side business making T-shirts, like the ones you see at the store for fifteen dollars with cheap print on them. It was cool, I thought, to make your own T-shirt and being at the age of 12 I was fascinated with how it all worked. I played around and I was allowed to stamp my own shirt that I still have to this day (although a little small). We checked into our hotel and then got some shut-eye because we had to leave late that night to make it to the Luc Yen Women’s Market by 5:30 a.m. when it opened. The trip was about 225 km on many dirt roads, today an estimated 3 hours and 32 minutes on Google Maps, but on our trip took us closer to 7 hours. The trip was bumpy and I was so sleepy it was painful. The guy in the back of the Mitsubishi Pajero was riding in the trunk clutching an AK-47; I’m sure it was even more uncomfortable for him.

I couldn’t wake up for the Women’s Market, as I had passed out in the back seat of the car, but at 6:30 the Men’s Market opened and my dad came back just before to wake me up and show me what he had purchased at the Women’s Market. I was able to purchase a few things: small spinels and tourmalines including an aquamarine crystal I still own. As we walked around the village the people of this area had not seen a Caucasian child before and found me very curious. At one point in the mid-afternoon I had about 300 people following me just to get a closer look and of course they loved to touch my hair, as it was good luck. I was also asked when I would marry by many of the young girls who seemed to be around my age and already had a two-year-old child. Farming villages are very different in Vietnam than here; it was quite a culture shock back then. I started thinking about what I should do for marriage and when I should have children. Ha! I was a cute and confused twelve-year-old. We stayed for just part of the day, as we had an appointment with the doctor on the return back to Hanoi that evening.

Our trip back was full of adventure. The first thing we saw was a small open-pit in the middle of a rice paddy field. They were in fact digging for gems and allowed my father and me to see what they were doing. I found a few small bits of ruby in the stream that they let me keep. The farmers who were digging brought us a few pieces they had found earlier that had promoted the digging. It was unfortunately nothing too exciting, but there was a cute little spinel. Regrettably due to some circumstances they were unable to sell us the piece, so we moved on to continue our journey.

We stopped off to visit a doctor that, rumor had it, owned a few great ruby crystals from Luc Yen. We were greeted warmly and treated to some very good hot tea. The doctor then brought out his collection of ruby and it was amazing because we had never seen this kind of quality before. Out of everything we saw in the Women’s and Men’s markets, his collection was far better. The problem was he was not really interested in selling any of the pieces from his collection piece by piece, as he loved them all. Ruby is very good luck in Vietnamese culture. He did tell us that if he was able to get enough for these then he could perhaps purchase the condo he wanted, and this was in 1997 so condo prices were about the value of his rubies. So he said he would maybe work it out. We of course wanted to buy it all but didn’t have enough money on us. As we negotiated and negotiated we were forced to call my mother at midnight in the U.S. so that we could do a money transfer. Unfortunately we found out there was really no way of transferring the money to Vietnam without using a Visa card that had heavy fees associated with it, but it would be done quickly. Luckily the doctor was able to negotiate a better price on the condominium and this allowed him to reduce the price of his collection so we could then finalize the deal. One of the crystals from that deal is on the cover of Gems & Gemology.

It was a long, bouncy, and slow ride back to Hanoi and we were all exhausted. It was about 6 p.m. when it started to get dark and I was nodding off trying to get some sleep. I remember waking up to a large bounce, undoubtedly caused by a big pothole. Soon after, we drove over train tracks when a loud bang and then shouting occurred. A motorcycle had hit us from behind and the driver appeared to be quite drunk. Our contact told us to keep our heads down and to not show anyone we were foreigners. Being twelve years old I just couldn’t help myself and I popped my head up as far as I dared to sneak a look. I remember watching our driver get out of the car, walking to the back by the motorcycle and was very calm as he approached the motorcyclist. In my memory I imagine him talking off aviator sunglasses, but I know he wasn’t wearing them since it was too dark, but what he did do was take out something from his pocket and flash it real quietly. I never got to see what it was, but as soon as it was out the driver of the motorcycle turned around and ran away, leaving behind his motorcycle and the crowd that had now grown around the drama. Later I found out he was working for the CID (central intelligence agency) in Vietnam and the guy who hit us obviously didn’t want to mess with that. After that our journey back to Hanoi continued without any problems. A few days later we headed home with the Southeast Asia trip concluded. [back to top]

Gems from the Red Land

The Pegmatite cover image

Members of the San Diego Mineral & Gem Society are lucky: they receive an electronic subscription to The Pegmatite, the nicely produced bulletin of the Society.

This month features “Gems from the Red Land,” an article by James A. Harrell, Professor Emeritus of Geology at the University of Toledo in Toledo, Ohio. The article is informed by 23 years and 33 visits to mines and quarries in Egypt, and beyond. The “Red Land” of the title, or Desheret, refers to the barren deserts that flank the rich Nile Valley and Delta. Lifeless, perhaps, but this is where Egyptians found lively carnelian and the meteoric Libyan Desert Glass as well as peridot, emerald, amazonite, amethyst, and turquoise, all of which are discussed and illustrated in the article.

This eight-page piece—focusing on some of the 31 varieties of material employed in Egyptian jewelry (and their mines)—should whet the appetite for Dr. Harrell’s in-progress book, Ancient Egyptian Rocks and Minerals: Varieties, Sources, Uses and Technologies. Although he has surveyed about 200 mines and quarries, in “Gems from the Red Land” Dr. Harrell drops tempting hints at the possibility of overlooked deposits of Dynastic (i.e., Pharaonic) varieties.

The Pegmatite is available to non-Society members in a reasonably-priced digital edition (as well as print edition). Details are on the San Diego Mineral & Gem Society website.

Nature’s Mirror: Asia’s Viewing Stones

Book cover image
In Modern Chinese Scholars’ Rocks, author Kemin Hu shares her expertise as a dealer and collector.

This past week, Southern California’s Bowers Museum featured special displays and lectures on bonsai and “viewing stones.” Bonsai, miniature living trees, will be familiar to many of our readers. But the contemplative appreciation of large-writ-small in bonsai also applies to stones. Viewing stones resemble landscapes, mountains, waterfalls, and more, as well as free-form sculptures, geometric designs, and anthropomorphic and bestial forms. Viewing stones can be large and weighty, suitable for a garden, for instance, or small enough for display on a desk.

Viewing stones (and/or the art of their appreciation) are known by different names: “scholar’s rocks” or Gongshi (China), Suseok (Korea), Suiseki (Japan). Glossary entries from these three Asian cultures indicate the connoisseurship that has developed over centuries regarding the stones’ aesthetic and ruminatory qualities.

The most prized of these stones have had little or no human help in achieving their display-state. Locality can be key to collectibility and in some cases, as with fine mineral specimens, sources may be played out. The smaller stones often are installed on a custom-made pedestal of carved wood or resin; they also can be placed in a shallow tray of sand. According to the Metropolitan Museum of Art, four aesthetic principles of the stones were codified by the Tang dynasty (618–907).

For a quick view of the variety of viewing stones from Asia and elsewhere, see examples from the collection of the National Bonsai Foundation. For detailed descriptions of some of the many types of Chinese scholars’s rocks, visit this blog by collector, dealer and author Kemin Hu.

Also at the Bowers…

Jade has been fashioned in China since the Neolithic period, and jade objects from as early as 3500 B.C.E. have been found there in tombs. An ongoing exhibit at the Bowers, “Ancient Arts of China: A 5000 Year Legacy” features jade objects, such as a jade cong (a square-shaped cylinder) that dates from between the 31st and 22nd centuries B.C.E.

Jewelry enthusiasts will want to browse “Read My Pins: The Madeleine Albright Collection” at the Bowers. Albright, who was the first female U.S. Secretary of State, became known for actively accessorizing by using her collection of brooches in understated and not-so-understated ways of sending a message regarding her mission as the country’s chief diplomat. The exhibition opens October 20. [back to top]

California Mining and Mineral Museum Robbed

Last Friday afternoon, a robbery occurred at the California State Mining and Mineral Museum in Mariposa. According to a State Parks press release, “a number of display cases, doors and other items were damaged by the approximately two suspects who entered the museum and stole an undetermined amount of precious minerals.” The parks agency was in the process of conducting an inventory of missing items, per the October 1 release. A Los Angeles Times story estimated the stolen loot to be worth as much as $2 million. That story claimed that the remaining valuables have been moved off site for the inventorying.

Any leads regarding this robbery should be given to the California Highway Patrol – Central Division Investigative Services Unit at 559.277.7250.

Photo Essays: Mines and Gold

Two photo essays, both posted in early August, caught our eye recently, and we thought we’d share them.

Destiny of Abandoned Mines

The Russian English-language entertainment blog, English Russia, posted a parcel of photos of abandoned mines. Pictured are mines for calcite, for the limestone used in the Kremlin’s original white stone walls and for muscovite. See “Destiny of Abandoned Mines” (and ignore the dopey ads…).

Gold

Boston Globe picture editor Lane Turner assembled 36 photos devoted to the extraction and processing of gold. Also included are photos of the people involved in the industry: miners, smiths, sellers, even protesters. See “Gold.” [back to top]

Pala Presents

Exhibition of Ron Gladnick Collection

By Will Larson

Pala Presents title image

With Pala Presents, we offer selections from the library of Pala International’s Bill Larson, who will share with us some of the wealth of information in the realm of minerals and mineralogy. The present article happens to be from the pen of Pala’s Will Larson.

During this year’s Westward Look Show in Tucson, the mineral collection featured on Collector’s Day was that of Ron Gladnick. In this year’s third edition of Mineralogical Almanac, Will Larson takes us through the metamorphosis of Gladnick’s collecting focus, which didn’t begin with fine mineral specimens.

We are pleased to reprint the article, “Exhibition of Ron Gladnick Collection” in our Pala Presents series.

The Sickler Family: Historic San Diego
County Gemstone Miners

Part IV of IV by Peter Bancroft

Pala Presents title image

With this edition of Pala Mineralis we conclude the four-part series published by Peter Bancroft in 1996 regarding San Diego County’s Sickler family.

This installment follows Fred Sickler (who would become Fred Sr.) and his new wife Florence Awilda Orcutt far from the tourmaline mines of Southern California—to Shungnak in the U.S. territory of Alaska. Fred had obtained civil service employment, but this was no desk job; he was to teach Inuit people how to domesticate reindeer, used for food, rather than be at the mercy of unpredictable migration patterns. During his decade in the area, Sickler’s photographs of the aurora borealis phenomenon were said to have been the first ever published. Florence Sickler, meanwhile, became a teacher, nurse and midwife to the native people.

Upon their return to Southern California, the Sicklers first moved to Los Angeles before Fred secured a job as foreman at the Pala Chief Mine, with which he would have an on-again, off-again relationship.

Two recent items from our sibling publication, Palagems Reflective Index, will be of interest to mineralophiles.

University of Arizona’s Virtual Geology

The University of Arizona has a thriving mineralogy program, and is host to the RRUFF Project, an integrated database of Raman spectra, X-ray diffraction and chemistry data for minerals. Two UA geoscientists also are involved in NASA’s Curiosity rover. Prof. Bob Downs and graduate student Shaunna Morrison are “primary data downlink leaders,” members of a team charged with IDing the minerals that come Curiosity’s way on its two-year journey on Mars. Read all about the high technology behind the project here.

The Weardale Giant

The Weardale Giant is the name given to a huge fluorite specimen uncovered recently in the Weardale mining district of northern England. It is also the name given to the legendary giants of the area, the blacksmiths Mug, Con and Ben, who could afford but one hammer between them. As they forged swords, they tossed the hammer back and forth, mindful of the curse upon them: if the hammer were to be dropped, they would vanish. It was Mug whose eyesight faltered along with his grasp; the hammer left a deep rift, now known as the Howden Valley.

But back to the specimen. The “Giant” was so big—likely half a ton—it took from July 10 to August 13 in order to pry it loose and move it down ramps to the mine’s transport. Then its matrix was sawed to make it more manageable, and down the mountainside for shipment to California. With any luck it will be displayed at the Tucson Gem and Mineral Show, in perfect harmony with the 2013 theme, fluorite.

Mineral and Mineralogy News

Blues Brothers: Scott and Lavinsky Honored with New Mineral Monikers

Scientists at the University of Arizona have identified two new minerals from the Wessels Mine, Kalahari Manganese Field, in north central South Africa. The material was produced in 2011, while miners searched for the well-known gem sugilite from this locality.

The first of the new minerals is scottyite, named in honor of Michael M. “Scotty” Scott, the first CEO of Apple Computer and gem collector extraordinaire. Scottyite forms millimetric masses of cobalt-blue color without cleavage. It has the chemical formula BaCu2Si2O7, and orthorhombic symmetry. The synthetic equivalent of scottyite has unusual magnetic properties, which makes it interesting to semiconductor researchers. (Before Apple, Scott was director of manufacturing at National Semiconductor.) More information and photographs are available at RRUFF. See also our 2005 profile of Scott’s collection at Palagems.com.

Scottyite is associated with the second new mineral, lavinskyite, a lithium copper silicate related to plancheite. The name honors Dr. Robert M. “Rob” Lavinsky, proprietor of the mineral superstore The Arkenstone. Lavinskyite forms blue, bright acicular crystals, in association with scottyite, richterite, and pectolite. More information and photographs are available at RRUFF.

The International Mineralogical Association just approved the new mineral appellations in June 2012. Congratulations!

Mickey Mouse from Uruguay

This is not the title of an outtake by Irish badboy-rockers Fatima Mansions. No, Mouseketeers, we’re referring to a plus-sized geodic amethyst from Artigas, a department in northern Uruguay. The photos of the Mickey-esque mammoth were sent to us by Sergio Aramburu, of StonesAgateAmethyst.com, purveyors of amethysts and agates from the region.

Amethyst photo image

Amethyst photo image

According to the website, the amethysts in this region were formed 130 million years ago. These formations were caused by gas-created cavities in lava, the walls of which gradually became encrusted with the violet variety of quartz silica via entry of a water solution.

The Sickler Family: Historic San Diego
County Gemstone Miners

Part III of IV by Peter Bancroft

Pala Presents title image

If you’ve already read our other offerings regarding the turn-of-the-century tourmaline craze, don’t pass up the third installment in Peter Bancroft’s profile of San Diego County’s Sickler family. It provides a look at the role played by Southern California Chinese immigrants in that chapter of the region’s gemstone trade.

Ah Quin and Employer photo image

Along the way, you’ll read of tourmaline-as-lotto-prize, knifings in the mines, a gunshot to the leg (via the Agua Tibia Ranch—we’re not kidding), orphan miners, the demise of the Sickler flour mill and more.

Part III concludes with the wanderings, both stateside and abroad, of kunzite discoverer Fred M. Sickler, Sr., who eventually became fluent in a septet of tongues as he studied mineralogy in Heidelberg, practiced journalism in Panama, and got mixed up in the Boer War, amongst other escapades.

Three recent items from our sibling publication, Palagems Reflective Index, will be of interest to mineralophiles.

Dr. Shah’s Gem & Jewelry Stamp Museum

In late June, Dr. Rajnikant Shah unveiled a virtual museum devoted to postage stamps of gemstones, minerals, jewelry, clocks, coins, and gold and silver. The museum database has over 10,000 items. Visitors can easily filter down to an area of particular interest. A search function also is available.

First Day Cover photo image
From Kenya, this first day cover features stamps depicting galena, rhodolite, ruby, grossular, fluorite, sapphire, tourmaline, aquamarine, trona, amazonite, gypsum, kyanite, amethyst and agate. See the website for larger image. (Image courtesy Dr. R. Shah)

According to the website, Dr. Shah began collecting at school in Jaipur, India, in the year of the country’s independence, 1947. The first stamps came from his parents, who lived in Burma. Thirty years later, he found himself in the United States in his family’s profession: gemstones. The travel that the business required gave him access to stamps from a variety of countries. In his choice of philatelic themes, he brought together his hobby with his profession.

Pala’s Carranza Connection

The following was a postscript to last month’s gem news item on the Colombian emerald trade vis-à-vis the impending death of Victor Carranza, the country’s “Emerald Czar.”

Pala International has owned and sold some of the world’s finest mineral specimens. As president Bill Larson likes to muse there are no absolute criteria for what is the finest, but often a piece comes along that is certainly revered. One such is the Yamile emerald specimen. Found in the Muzo mine and named for Victor Carranza’s youngest daughter, it is now in the collection of businesswoman and philanthropist Lyda Hill, perhaps destined to grace the hall of minerals in the Dallas Museum of Nature and Science. (A merger of three Dallas museums, including the MNS, will result in a new museum, opening in January, the Perot Museum of Nature and Science.)

Yamile Emerald photo image

Pala’s involvement began with Bill Larson being shown the piece in Munich in the late 1990s. The price at that time was in the multi-millions of dollars. The interesting part for Larson was not only the two large, superb colored emerald crystals typical of Muzo, but also that the mineral specimen had been carefully removed from a pocket so that it retained perfect, large, beautiful twinned calcite crystals. Pala followed the specimen until it resurfaced a few years later, at a considerably reduced price. This time the piece was in possession of an emerald dealer who had supplied cut emeralds to Pala for years. Larson suggested a unique situation: an offer of purchasing half and leaving Carranza with 50% ownership. This deal was approved and Larson called upon his long-time friend Wayne Thompson to purchase 25%. This he did. The emerald would later be featured on page 157 in Thompson’s now-famous book Ikons: Classics and Contemporary Masterpieces of Mineralogy.

Bill Boyajian photo image

Pala cleaned the specimen and had several of the broken areas trimmed to near perfection. After holding the specimen for a year, Pala sold the piece to Fine Minerals International. The profit was split among the partners. Fine Minerals took the risk and trimmed away the few remaining flaws and then later sold the specimen to Lyda Hill. Hopefully the public will be able to visit this great memory of the Muzo mines and the legend of the Emerald Czar. [back to top]

Tourmaline Deposits of the Americas

From a lecture in Italy by Brian Cook

Brian Cook of Nature’s Geometry takes us on a tour of three famous mining regions accompanied by some photos from geography to geology, from specimens to gems and jewelry.

Starting here in the U.S., Cook presents the two great tourmaline mining areas at the furthest extremities of the country, from the blue and green tourmaline of Maine to the pink tourmaline of Southern California. Then, heading south, we go to Brazil for the wild array of tourmalines, finishing with an in-depth look at the most rare and famous tourmaline variety of all… paraiba.
