Beryl Var. Emerald
stock #A7 -545
Chivor
Boyaca, Colombia
14 x 6 x 3 MM (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.
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.
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.
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.
Torbernite (old classic- type locale)
stock #0797-JM-3610
Johanngeorgenstadt
Saxony, Germany
6.7 x 4.3 x 4.8 CM (cabinet)
price: $320
pre Tucson 2015 update

A fine, old German Torbernite from the Dr. Moritz Lechner collection (his number 7258 is attached), This important collection was begun in the 1850's and the number indicates this was likely added in about 1890. The collection was built from other significant old collections he purchased during those years, so this piece may be even older. The first descriptions of the mineral from here date to the 1770's. Ex John Marshall collection, this piece has a good relatively dense coverage of sharp plates with a nice deep green color. This locale is known for great Mimetites and some rarities, but it is also the type locality for Torbernite.
Carrollite
stock #Alec 12-271
KOV open cut, Kamoto, Kolwezi
Katanga (Shaba), Democratic Republic of Congo (Zaire)
3.2 x 1.9 x 2.6 CM (small miniature/ large thumbnail (toenail))
price: $250
pre Tucson 2015 update

A quite fine, sharp, lustrous, undamaged and well positioned Carrollite crystal on matrix. Good Carrollites have gotten hard to find. The great discoveries in the Congo were the best by far worldwide, but no fine pieces have come out in years, even damaged examples are scarce. This specimen though small has fine form with nice growth patterns on the faces. The crystal is 1.4 CM across.
Stibnite -Flattened prismatic crystals with Barite, Quartz
stock #Alec- 16-162
Cavnic (Kapnic)
Maramures, Romania
8.8 x7.7 x 5 CM (cabinet)
price: $290
pre Tucson 2015 update

A nicely composed, lustrous and sharp Roumanian specimen from the classic Cavnic mines. Since this locality closed the unique habits of Cavnic Stibnites have become sought after. This is in very good condition overall, but for a perfectionsist this is not perfect. Edge damage where this was removed is noted,magnification reveals more tiny chips and contacts elsewhere but most are less than a mm in size. Some rough looking terminations are not damaged but are the more hackly type nestled in with the prismatic ones. The main areas are mostly undamaged, and the most prominent crystals are fine. This displays well the rare flat-habit metallic Stibnites in an esthetic array on contrasting matrix. Affordable with nice form and reasonable shape for and older, delicate mineral.
Pyromorphite- Exceptional for locale
stock #0701-JM-XX
Little Giant Mine, Mullan, Coeur d' Arlene District, Shoshone County
Idaho, United States
11.3 x 6 x 4.3 CM (cabinet)
price: $950
pre Tucson 2015 update

A big and well crystallized Pyromorphite from a little known location, the Little Giant Mine. This specimen was in the famed Pyro suite of John Marshall, the best example from Little Giant he had been seen in his 60 years of Pyromorphite collecting. Later discoveries nearby at Bunker Hill mine are much more well known, but this locality had a few fine specimens before then. This is one of them and is if very good condition, has 2 generations of growth with crystals reaching 7mm densely covering the matrix.
