Prehnite and Tanzanite
We offer a rare and remarkable specimen of well crystallized greenish prehnite in a fine cockscomb specimen. This beautiful group was found earlier this year at the Merelani Mine, Arusha, Tanzania.
To make the piece even more exciting and interesting, a well terminated bicolor (yellow and blue) tanzanite (3.0 x 2.5 cm in height) has grown into the side of this prehnite.
This specimen was featured in the October 2015 issue of our newsletter Pala Mineralis
