This month we feature a massive quartz from Pakistan. It's an impressive size even for a fine quartz crystal, but this one has an added dimension that makes it quite unique. From its original crystalized state an exsolution process has created beautifully etched crystal faces with wild jagged patterns. The crystal has maintained its transparency on the inside but the surface has been transformed into a complex geometric puzzle. There is even a linear vug wrapping around the crystal like a cliffside cavern (see photos below).

Quartz

Beauty on many levels and not to mention pristine with no real damage…a complete specimen. From the Shigar Valley, Gilgit-Baltistan in the northern areas of Pakistan.

Mineral and Mineralogy News

thINK Minerals

Magazine

INK Publications, otherwise known as Connecticut's Art, Culture and Lifestyle Magazine, often covers local jewelry and fashion. Last month, INK profiled Irish transplant Tina Ashmore who began jewelry design as a child using the materials at hand: aluminum foil for rings and bracelets and colored wire insulation for beads. Her creations today display a love of color as she fashions clusters of grape-like berries from pearls and handcut gemstones like rhodolite garnet, citrine, amethyst, iolite and peridot. In November INK went behind the scenes at Becker's Diamonds & Fine Jewelry in West Hartford to find that proprietor Paul Becker himself knew by age thirteen what his life's work would be.

This month we were given a peek at an article, "David Friend Hall: Dazzle, Adventure, and Vision," by Laurencia Ciprus, who is a fine artist and interior designer as well as a journalist. So it shouldn't surprise the reader as she begins the story, "Infinite beauty accessorizes the natural world in repetitive patterns: Fibonacci numbers in proportioned cubicles of the chambered nautilus, six-fold radial symmetry in the delicate armature of a snowflake, or fractal spikes and spirals in a clutch of Romanesco Broccoli hiding in the crisper." Ciprus goes on to give a thumbnail sketch of the Yale Peabody Museum of Natural History, its collection and contributors, "a roster of scientific seers, scholars, and adventurers," to which must be added the name of David Friend, a cofounder of the Carbonite cloud backup service as well as synthesizer manufacturer ARP Instruments. As readers of our own pages know, the Peabody Museum recently unveiled the David Friend Hall, a gallery devoted to the exhibition of scores of world-class gem and mineral specimens.

In the article Friend compares the major private mineral collections with those in the art world, so the task for him and the team at Yale in obtaining suitable pieces was made somewhat easier. Each piece has a story behind it and, appropriately for a gallery named after a man who cut his teeth on tech's cutting edge, six of those stories are told by a mobile app.

Ciprus provides descriptions of several of the David Friend Hall highlights as the history of the permanent Peabody collection. The article is copiously illustrated with images, some of which we've reproduced ourselves as well as others we haven't. Even if you've seen some of the specimen photos, you may be surprised at their scale when confronted with them in the context of the Hall's landscape in photos by A. Vincent Scarano.


Lithology & Oenology

The vintners are playing up a key element of terroir, wearing their soils on their sleeves.

The vintners are playing up a key element of terroir, wearing their soils on their sleeves.

In the 1990s when my wife Andrea and I (your editor) would travel up the California coast, we'd often take side trips to the wineries of Paso Robles. One year, on a jaunt with the whole Hughes clan, at a winery called Dover Canyon I was quite taken with a Viognier flaunting a nose so floral, each whiff from the tasting room's slender flute-like stemware evoked a Provençal hillside. On our own, Andrea and I came upon Adelaida, a winery in the hills ten miles due west of Paso Robles. At the time, the tasting room was little more than a countertop in the warehouse. Regardless, we fell in love with Adelaida's Zinfandel and joined its wine club, Tribe of Esau. I recall on one return visit, we tried to describe what that Zin did to our tongues, but our host wasn't from the winery; he was only a volunteer, paid in freebies.

In the spring of '02 we had a delicious déjà vu when my parents celebrated their 50th wedding anniversary by taking the clan to Paris and south as far as Marseilles. While at a country inn just outside Aix-en-Provence, I used my best pidgin French to cajole the staff into planning a wine tasting route for only Andrea and me. Little did I know that the sixty-minute straight-line-road past Luberon Park to the Rhone Valley would take us to one of the most famous wine regions in the world, Châteauneuf-du-Pape. In a single cave à vin—or cellar (though this one really was a cave)—we sampled many reds from around the region. Complete novices to French wine and thus to this storied area that literally takes its name from Pope Clement V's transfer of his court from Poitiers to Avignon and his successor John XXII's construction of the "new castle," we nonetheless recognized the same tongue-twisting je-ne-sais-quois from Paso Robles. The dollar was strong against the euro and we made a killing, packing what now would be a fortune in our luggage to take home. The day of our return, Andrea read in the Los Angeles Times Magazine that "the cooler and rockier vineyards of the [Paso Robles] region's west side resemble the southern Rhone in France both in climate and soil."

So when Pala International's Bill Larson sent me a Bloomberg article titled "Soil, Not Grapes, Is the Latest Must-Know When Picking a Wine" my tongue's memory was piqued. In her story, Bloomberg's wine and spirits columnist Erin McCoy takes on "the dirty side of wine": soils alluvial, limestone, granitic, slaty, volcanic, and more. McCoy and her sources use words like smoky, savory, supple, smooth, edgy, and complex, depending on the geology. A fad? McCoy points to award-winning Southern chef Sean Brock whose farm-to-table Husk restaurants list wines not by region, but by rock type.

The lithology of oenology is not without naysayers, and McCoy quotes a geologist who says there's no direct link between geology and taste. But McCoy is convinced. She takes you, A to V, through six soil types and seven wines—but caveat emptor. This baker's half-dozen could set you back an average of $100 a bottle.

Pala Presents

The Emerald Deposits of Muzo, Colombia

by Joseph E. Pogue, Ph.D.

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

Joseph Ezekiel Pogue Jr. (1887–1971) was a geologist, petroleum engineer, and economist, receiving his doctorate in geology from Yale in 1909. That same year he joined the Smithsonian as assistant curator until 1913, spending 1911 as a special student at the University of Heidelberg. He joined the faculty of Northwestern in 1914 after a year with the U.S. Geological Survey as associate geologist. Leaving Northwestern in 1917, he returned to the Smithsonian as mineral technician. The next year he became assistant director of the Bureau of Oil Conservation for the U.S. Fuel Administration. According to his NCpedia profile, his career remained in the field of petroleum.

Mineral and gemstone enthusiasts will be interested in his monograph The Turquoise (1915) as well as the present paper, The Emerald Deposits of Muzo, Colombia (1916). This latter study is a readable text, helpfully illustrated.

In this edition of our newsletter we present Part 2 of The Emerald Deposits of Muzo, Colombia, which covers minerals, age, origin, mining methods, and production.
