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.
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.
SOLD Scheelite on Muscovite
stock #SOLD 6.2-112
Mt. Xuebaoding, Pingwu Co., Mianyang Pref.
Sichuan, China
9 x 5.7 x 5.3 CM (cabinet)
price: $0
pre Tucson 2015 update

One of the worlds greatest localities is Xuebaoding, China and its most desirable mineral is Scheelite. This piece has a very sharp 5.1 CM crystal well perched and exposed on a Muscovite matrix that also has a few smaller Scheelites. The color is a pleasing mid orange-yellow, so it is not the deep orange red that sells for astronomical prices. Otherwise, the luster is a bright "wet" look, and it displays well. Fine condition overall, the esthetics are also well above average. From 2004 vintage finds, this quality is much harder to get now.
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.
SOLD Andradite on Hedenbergite
stock #SOLD A-10-575
Serifos Island, Cyclade Islands
Kyklades Prefecture, Aegean Islands, Greece
5.1 x 4.3 x 3.3 CM (miniature)
price: $0
pre Tucson 2015 update

A wonderfully formed miniature that shows well the Serifos habit with color zoning on the Garnet. In undamaged condition, this displays well from every angle. The garnets are up to 8MM in size in a 4.3 CM cluster. They are not gemmy (gem examples usually have little or no color zoning on edges) but they do have a great display character.
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.
