Fluor-Buergerite -type locality
stock #18.1-291
Mexquitic
San Luis Potosi, Mexico
1.5 x 1.2 x .9 CM (thumbnail)
price: $390
Worldwide mix summer

Unusually well formed thumbnail of the rare Tourmaline specie Fluor-Buergerite from the type locality. These were found just once in the 1960 era and not since. This main crystal at 1.2 CM is very large for the specie and especially choice. Chocolate brown and in excellent condition, this has a very attractive arrangement with a cluster of smaller crystals and a tiny matrix. Formerly named Beurgerite, this is not often available and very rarely in such a sharp, textbook form.
Danburite (gemmy pink) on Calcite
stock #16.1-277
Charcas
San Luis Potosi, Mexico
5.3 x 5.2 x 5.2 CM (cabinet)
price: $280
Winter 2016-17

Set like a pink jewel in a cluster of Calcite crystals, this equant Danburite is in outstanding condition. What may look like damage is simply internal veils seen inside the crystal. Very esthetic, this displays well from several angles. There is chipping on some calcite mostly on the underside and back, but not seen on the logical display side. A modern classic, choice.
Calcite- Optically clear single crystal ex. W. I. Johansson
stock #15.1-719
Charcas
San Luis Potosi, Mexico
4.5 x 3.1 x 2.2 CM (miniature)
price: $300
Winter 2016-17

Slightly frosted on some faces, sharp, clear and in fine condition, this old specimen is from 1960s vintage finds at Charcas. Selective frosting adds to the visual interest and the form is textbook perfect. The termination shows a nice effect with the selected areas outlining a central hexagon. Nothing quite like these Calcites has since been found.
Datolite
stock #ALEC-29-059
Charcas
San Luis Potosi, Mexico
6.4 x 6 x 3 CM (cabinet)
price: $275
pre Tucson 2015 update

Great color and luster, this is a Datolite from Mexico that looks much more like a good Russian specimen. From a small find in late 2013, this has the form, clarity and quality of the top few percent. Some edge chipping/ contacts is inevitable but overall in very good condition.
