Amazonite (Microcline) & Smoky Quartz
stock #15.1-300
Mona Mine, Pikes Peak, El Paso Co.
Colorado, United States
4.3 x 4.7 x 3.8 CM (miniature)
price: $440
Post Tucson 2015

Extra intense color for a Microcline, this miniature from Pikes Peak area, Colorado and has much deeper blue green color than most Colorado localities. In fine condition damage-wise, there is a nice association of Cleavelandite blades nestled between the crystals. An American classic locality, this is relatively recent find from a small working claim. Better in person, with great display impact in a small size.
Agardite (Ce) on Calcite & Quartz
stock #15.1-298
Tsumeb
Otjikoto Region, Namibia
5.7 x 3 x 2.8 CM (cabinet)
price: $350
Post Tucson 2015

The rare Cerium bearing Copper Arsenate mineral Agardite from Tsumeb was found on the 30th level several years ago. This specimen is a fairly rich example with eye visible zones and with a little Duftite as well. The matrix is scattered on several sides with sprays of micro radiating Agardite crystals. The Calcite crystals are rhombohedral form and have unknown inclusions. Not really a cabinet display specimen as the Agardites are so tiny as all are, but nice under the microscope, this piece could make many micro-mounts.
Apophyllite with Prehnite, Quartz (classic locale)
stock #13.1-191
Centreville, Culpeper Basin, Fairfax County
Virginia, United States
6.4 x 5.8 x 4.3 CM (cabinet)
price: $240
Post Tucson 2015

A classic specimen from Centreville, Virginia with sharp, well-defined white Apophyllite crystals contrasting with green Prehnites. This example is in excellent condition, good display quality for the size and quite affordable for one of these.
Scapolite (purple gem crystal) v. Marialite
stock #7.AE-474
Deposit 1677, Subashi, Aketao Co., Kizilsu Pref.
Xinjiang Autonomous Region, China
1.7 x 1 x .8 CM (thumbnail)
price: $240
Post Tucson 2015

A rare Chinese gem Scapolite with very intense purple color, much of which is clear enough to facet. We see very few specimens of any sort from Xinjiang, this Scapolite was from a small one time find over ten years ago when the deposit was listed as "Daftar". Analysis shows that these are a Marialite variety with some chrome adding the color. This is much deeper hue than most. Some chipping is noted with 10x magnification so this is not for perfectionists but it is still a very good, richly colored crystal that shows some clear dichroism.
Fluorite w. Sphalerite
stock #15.1-029
Elmwood Mine, Carthage
Tennessee, United States
3.9 x 3.2 x 3.1 CM (miniature)
price: $85
Post Tucson 2015

A simple attractive small specimen from the now classic Elmwood mine. An affordable Fluorite on Sphalerite with frosted faces, lilac hue, subtle zoning and nice contrast. Not perfect, so not expensive - there is some very small edge rubbing and a cleaved crystal at the rear. Still attractive and a good value there have not been many Fluorites recovered in the past 2 years.
Anglesite on Galena
stock #15.1-386
Touissit, Touissit-Bou Beker Dist., Jerada Province
Oujada-Angad Province, Oriental Region, Morocco
6 x 3.7 x 3.4 CM (cabinet)
price: $650
Post Tucson 2015

Several super sharp, gemmy clear Anglesites are scattered on this Galena matrix. The largest is about 2CM long and stands above the matrix nicely. There is a repair on the specimen that is more or less invisible but it is there and keeps the price lower. Lots better in person and overall in fine condition, this is simply an esthetic, fine colorless Anglesite
Calcite
stock #A7-028-(1284)
Egremont, West Cumberland Iron Field
Cumberland, Cumbria, England
5.3 x 4.8 x 3.3 CM (cabinet)
price: $330
Post Tucson 2015

Classic old English Calcite from the Egremont mines, Ex Larry White collection. The habit and clarity are typical of this region and these Calcite can be very expensive when they turn up at shows. Fine condition and eye clean (no damage noted by naked eye)the crystals have a slightly milky look but are still fully transparent.
Native Silver
stock #7.AE-205
Elura Mine, Cobar, Robinson Co.
New South Wales, Australia
4 x 2.2 x 1.4 CM (miniature)
price: $490
Post Tucson 2015

One of the very best most detailed Elura Silvers I have ever seen. The Elura mine is the source of a distinctive habit of crystallized Silver, this being a superb example. Herringbone crystals and elongated spinel twins, some of which are flattened are all joined in a tree like sculpture. Excellent patina and in perfect condition, no damage can be found even at 30X magnification. These have become scarce in recent years and this quality was never common.
