Vesuvianite (rare color, classic, closed location)
stock #17.AL-496
Jeffrey Mine, Asbestos
Quebec, Canada
4.6 x 3.5 x 2.8 CM (miniature)
price: $1950
pre Tucson 2015 update

Intense emerald green color (not the usual deep green) often labeled as Chrome Vesuvianite is one of the rarest and most desirable. Jeffrey mine Vesuvianites are without peer in the mineral world, the color array is incredible and this green example is first rate. The main crystals are up to 2.5 CM, and doubly terminated but smaller ones are only singly. The terminations on most of the crystals are an unusual flat or multi stepped type that may look like damage with a quick glance . There is some damage on this piece seen when studied carefully and some evidence of re-crystallization on a few zones. Still overall this is a fine display piece as nearly all of these that exist do have at least a little damage. Far better in person.
Silver crystals on Copper crystals
stock #Alec-19-201
Osceola Mine, Osceola, Houghton County
Michigan, United States
4.9 x 2.7 x 1.6 CM (miniature)
price: $320
pre Tucson 2015 update

An odd yet quite attractive specimen which is very well crystallized. The matrix is mostly all copper, some of it is crystallized with flattened octahedra and some standing fingers of crystals. The main event is the Silver that is crystallized in twisting fingers and branches contrasting to the copper. A little Malachite and a blue mineral (Chalcanthite?) are visible too. The blue could be cleaned off but it adds interest as is in my opinion. The condition is perfect, the esthetics are distinctive and not typical.
Orpiment and Calcite
stock #Alec-15-207
Shimen (Jiepiayu) Mine, Shimen County, Changde Prefecture
Hunan, China
8 x 6.8 x 7.9 CM (cabinet)
price: $380
pre Tucson 2015 update

Sharp white Calcite scalenohedrons make a wonderful contrast to the orange red crystals of Orpiment. The Orpiment is sharp and well terminated with translucent to gemmy area. In excellent condition for such a delicate mineral, this displays well from all sides. These came on the market 8-9 years ago but have been getting scarce now, especially in this higher quality specimen. From the Shields Flynn/ Frances Trafford 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.
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.
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.
