Spinel -Classic old locale
stock #15.1-168
Amity, Orange County
New York, United States
3.3 x 3.2 x 2.6 CM (miniature)
price: $250
Post Tucson 2015

A very good example of Amity NY Spinel that was world famed when first found in the 1840's. The exact locale is now lost today, but occasional small finds are made in the area. This is an old specimen in fine condition, sharp, complete and with a nice contrast to the matrix.
Pyrolusite /Hausmannite pseudo after Manganite
stock #ALEC-10-857
Ilmenau
Thuringia, Germany
7.8 x 4.3 x 3.5 CM (cabinet)
price: $280
Post Tucson 2015

A very old piece formerly from collections of Ara Dildalion and William Hladysz, but likely far older. The forms of the original Manganite crystals are very clearly seen are are up to 6.8 C. The luster of the piece is overall a dull "sooty" black but some faces and terminations have a shiny black luster as well. This region is the source of the great classic Manganites that are especially sought after. This sort of Psuedomorph is not especially pretty but they are rare and this one has especially good form
Scapolite (purple gem crystal) v. Marialite
stock #7AE-474
Deposit 1677, Subashi, Aketao Co., Kizilsu Pref. Formerly Daftar
Xinjiang, 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.
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.
Microcline v. Amazonite (Manebach twin)
stock #ALEC-22-277
Blue Nugget Claim, Crystal Peak area, Park Co.
Colorado, United States
6.6 x 4.4 x 4.6 CM (cabinet)
price: $180
Post Tucson 2015

Textbook form crystal with classic habit Manebach twin and nice green color. This specimen is repaired (reassembled) as it had split along the twin plane in the pocket. A further growth of the separate parts has prevented the repair from seamless. Despite that the structure and form are very good and this is an excellent, affordable example of the twin law.
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 micromounts.
Amethyst
stock #15.1-411
Boekenhoutshoek, Mkobola
Mpumalanga, South Africa
5.1 x 3.4 x 3.4 CM (miniature)
price: $160
Post Tucson 2015

South African "cactus" quartz is a popular commodity in the mineral market, but the deeper purple hues are the most rare and few are available. This deep hued specimen is in perfect undamaged condition with great form and shows the termination "star" of zoned purple that is most desirable. Good cactus Quartz is one of the bargains of the mineral world.
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 Cleavlandite 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.
