Calcite - stacked hexagons
stock #18-AX-12-440
San Luis Potosi, Mexico
3.8 x 3.4 x 3.3 CM (miniature)
price: $130

A classic habit Calcite from Charcas, Mexico which is a stack of thick (and a few thin) hexagons in a staggered alignment. Vividly fluorescent as well, the luster is bright on the side faces, the flat terminal faces are a pearly matte so much less shiny. The bottom has contacts but there is no damage. Translucent to slightly transparent, the crystals are internally zoned.

Smithsonite with Hemimorphite
stock #0770-JM-4361
Hidden Treasure Mine,Oquirrh Mts. Tooele County
Utah, United States
7.8 x 6.7 x 3.8 CM (cabinet)
price: $490

Choice old Smithsonite with botryoidal blue-green surface sprinkled with lustrous small Hemimorphite crystals. Ex. John Marshall collection, a fine piece from the Hidden Treasure Mine (Utah); this is more than 40 years old. The matrix is especially nice as it shows the unusual layered stacking of Smithsonite and has spaces between each layer. The Hidden Treasure Mine is just that, - A less well-known or hidden treasure which has produced some fantastic specimens.

Descloizite - stacked crystals
stock #19.1-250
Berg Aukus, Grootfontein District
Otjozondjupa Region, Namibia
4.7 x 2.2 x 1.6 CM (miniature)
price: $520

Red to brown, lustrous Descloizite crystals arranged in stacked alignments. A classic form and in fantastic condition, these Descloizites are especially bright darker on one side and a less lustrous, more light color on the other. The crystals are translucent, with good back-lighting they glow a warm root-beer hue. On the thin edges the crystals are more red. In excellent condition as seen, this is a really nice esthetic specimen. Berg Aukus is certainly the premier locality for Descloizite, no place else on earth has formed anything close to this fine quality. Far better in person too.

Barite (Baryte)
stock #0625-JM-2848
Rock Candy Mine, Grand Forks, Greenwood Mining Division
British Colombia, Canada
10.6 x 7.5 x 5.7 CM (cabinet)
price: $390

Sharp transparent Barite crystals rising like a chain of mountains above a sparkling landscape of tiny Barite crystals. Bright yellow-orange color with fine luster from the finds several decades ago at the Rock Candy Mine, British Colombia, Canada. Attractive cabinet sized specimen from the collection of John Marshall (his label is included). Close exam shows a few small rough edges on some crystals but most are quite perfect and sharp. For such a delicate, fragile mineral this is in amazing condition. An excellent example from this locale and a nice Barite from any place.

Arsenopyrite - aligned crystal structures
stock #16.1-060
Huanggang Mine, Chifeng Prefecture, Hexigten Banner, Ulanhead League
Inner Mongolia Region, China
4.8 x 4.6 x 3.9 CM (miniature)
price: $280

A remarkable and impressive form with hundreds of small Arsenopyrite crystals aligned in sweeping arcs. From the recent finds at the Huanggang Mine in Inner Mongolia, the crystals have a moderate or satiny metallic luster. The presenting display face is perfect, undamaged however the bottom and part of one side is rough. That area is not distracting in normal display.

Fluorite - penetration twins
stock #4.2-396
Xianghualing Mine, Linwu County, Chenzhou Pref.
Hunan Province, China
12.7 x 7.3 x 5.7 CM (cabinet)
price: $440

A very unusual, older (2002) Chinese Fluorite from Xianghauling with several distinct penetration twins. Some white zoning is seen on close exam but these are mostly a uniform mint green, transparent to translucent, and vividly fluorescent. This is very unlike most of the later finds from this area, the UV response is also very rare. The largest crystals have very classic habit twins up to 2.7 CM across. This somewhat resembles English Fluorites as this twinning if far more common from there. We have seen only a handful of this sort from China and this is a very choice example as seen.

Rhodochrosite with Fluorite and Goethite
stock #16.1-498-(CN543)
Santa Eulalia, Aquiles Serdan
Chihuahua, Mexico
7.8 x 5.8 x 4 CM (cabinet)
price: $280

Small bright red transparent Rhodochrosite crystals scattered in an open vug on a dark matrix. The Rhodochrosites are perched on tiny fingers and knobs of Goethite with a few small crystals of pale colored Fluorite making a nice addition. Minimal damage, the specimen displays well; it could also be trimmed to a miniature size but we like it just like this. Ex Charles M Noll collection, his label is also included.

Vivianite - radiating needle habit
stock #20.1-253
Kerch Penninsula, Crimea Penninsula
Crimea Oblast, Russia
5.6 x 3.3 x 2.3 CM (cabinet)
price: $240

Pointed blue green blades and needles of Vivianite in a radiating cluster. Formed on a soft Sandstone matrix this is an older piece (the original labels say "Ukraine") from well before the Russian annexation of this area. The crystals are in fine condition, there is some contacting but no real damage. With good lighting the color is a dark blue to green but otherwise this does look darker. Nicer in person, a good, delicate spray habit example of this famed find.
