Beryl Var. Emerald
stock #A7 -545
Chivor
Boyaca, Colombia
1.4 x .6 x .3 CM (thumbnail)
price: $350
pre Tucson 2015 update

Small but absolutely perfect, glass clear and bright green Emerald crystal from the famed Chivor mine. Two perfectly terminated crystals are side by side are see-thru gemmy. The glassy luster and clarity make this hard to do justice to in a photo, it is better in person. Vintage about 1990, ex Larry White collection.
Boracite (2 generations) with Hilgardite
stock #14.1-063
Boulby Mine, Loftus
North Yorkshire, England
3 x 2.3 x 1.8 CM (thumbnail)
price: $150
pre Tucson 2015 update

A colorful bright sparkling thumbnail from the classic English locale of Boulby. The Boracite is in two generations and two colors, the later is gem clear blue crystals resting on the earlier green. The rare mineral Hilgardite is in bright orange crystals in singles and clusters. By far the worlds best Hilgardite comes from this mine and these are fine crystals for the specie. Many nice display angles on this one, in excellent condition and reasonably priced.
Serandite with Analcime
stock #12.1-238
Poudrette Quarry, Mont Saint-Hilaire
Quebec, Canada
3.7 x 2.6 x 1.4 CM (miniature)
price: $225
pre Tucson 2015 update

A sharp salmon-pink Serandite crystal is almost completely covered with small, sparkling gem clear analcimes much like a coating of ice. The few larger Analcimes growing from some faces are the typical milky white and are a nice contrast to the Serandite. A very nice example from mining over 30 years ago at Mt St Hillaire. Excellent condition.
Calcite over Stibnite
stock #13.1-233
Quincy Mine, Hancock, Houghton County
Guizoh, China
7 x 5.2 x 6.2 CM (cabinet)
price: $90


An odd, strangely attractive specimen with an interesting form, This is a series of fingerlike growths studded with scalenohedral calcite crystals. These have grown over slender crystals of Stibnite which are now completely covered by the reddish calcite. It is possible to see on the bottom where this was broken off the Stibnites remain.
Prehnite (classic alpine crystal habit )
stock #14.1-194
Cavradi, Tavetsch, Grissons
Grischun (Grisons), Switzerland
3.2 x 2.4 x 2.2 CM (thumbnail)
price: $240
pre Tucson 2015 update

A very distinctive thumbnail with excellent crystal form that is typical of fine alpine Prehnite. Ex. Wendy Melanson's great thumbnail collection, her locale lists Cavradi Gorge Tavetsch, however it is likely that this came from Tavetsch but maybe not in Cavradi itself, but it right for that area. No matter what this is an elegant piece showing well crystallized colorless "pinwheel" forms in an attractive 3 dimensional arrangement. No damage, great luster.
Mimetite
stock #14.1-065
Elura Mine, Cobar, Robinson Co.
New South Wales, Australia
3.2 x 2.7 x 1.6 CM (small miniature/ large thumbnail (toenail))
price: $275
pre Tucson 2015 update

A good toenail sized Mimetite from the Elura Mine with nice structure and definition. The top Elura Mimetites were once some of the best ever found, this piece is not of that calibre but it is nice and not crazy expensive either. Very clean condition damage wise, the crystals reach 1.2 CM and show color zoning. Magnification shows a second generation of smaller crystals and a coating of yellow to red brown has formed on all the crystals. It seems they are yellow to green and more glassy underneath the coating, which might be removable with solvents. A good value, these are now getting scarce.
Elbaite -rare fibrous-zoned achroite, verdelite and indicolite crystal
stock #Alec-7-150-504
Aracuai, Jequitinhonha Valley
Minas Gerais, Brazil
3.9 x 1.9 x 1.9 CM (miniature)
price: $380
pre Tucson 2015 update

An very unusual older specimen from a find in the 1970's at Aracuai. The tourmaline crystal is both etched and prismatic with a large fibrous zone in the middle. The color zoning is unusual and includes the uncommon colorless (achroite) variety. Ex Larry White collection, this is an attractive oddity and very different from other finds of fibrous Tourmalines. In good but not perfect condition, there is contacting and chips but not badly noticable from some angles.
Selenite (clear gypsum)
stock #Alec 10-419
Naica Mine. Naica, Municipio de Saucillo
Chihuahua, Mexico
7.1 x 3.1 x 2.1 CM (cabinet)
price: $480
pre Tucson 2015 update

Glass clear and super sharp, a single gem clear crystal perched on a gossan matrix. Classic locale, this is vintage 1970's ex. Wm. Hladysz collection. The clarity and size is impressive as is the overall condition, the crystal is contacted at the back where attached to the matrix but otherwise in fine shape. For a delicate mineral this is a textbook perfect example, and better in person.
