Minas Gerais, Brazil
8.3 x 6.4 x 4.3 CM (cabinet)

Spring update

A superb large euhedral crystal (7.8 CM tall) dominates a cluster of smaller crystals. Sharp, complete all around and undamaged, this is an incredible example from the famous Linopolis find thirty years ago. Micro crystals of some unidentified Phosphates are also scattered on the specimen and add a little sparkle. Ex Charles Noll collection, the original label call this Herderite as these wwere known then, now understood to be Hydroxlherderite. Most faces show a glassy luster and are transparent in parts. The color of Hydroxylherderite from here can vary widely, this one is mostly light violet-purple but with some zones of greenish, grey and orange. Display well from all sides and the main crystal is textbook quality. These only appear now from old collections like this.
Herderite (hydroxl Herderite) on Microcline
stock #Alec-14-368
Shigar, Skardu District, Baltistan
Gilgit-Baltistan, Pakistan
5.5 x 4x 3.5 CM (cabinet)
price: $900


From the late 1990s vintage finds, a very distinctive, doubly terminated gem crystal perched on a crystal section of Microcline. The 3 CM long Herderite is in perfect condition and shows textbook form. Excellent esthetics and a slight color change from blueish to greenish in different light sources. A far better than average piece, and there has been nothing new on the market for several years.
