Olivenite on Quartz - classic Cornwall
stock #12.1-022
Wheal Carpenter, Fraddam, Gwinear-Gwithian
Cornwall, England
5.1 x 3.9 x 4.1 CM (small cabinet/large miniature)
price: $690

Well-crystallized Olivenites are protected in a shallow vug lined with Quartz crystals. In excellent condition, ex Don Shultz collection. The Olivenites are deep green, glassy lustrous and many are doubly terminated. From Wheal Carpenter according to the original label, this is a small mine that operated sporadically from 1792-1855. We have never seen another example from this locality. This specimen is similar to other Olivenites from this region, though the crystals here are a bit larger than others we have seen.

Cinnabar on Dolomite with Quartz
stock #6.2-043
Chatian Mine, Fenghuang
Hunan Province, China
6.1 x 3.8 x 3.4 CM (cabinet)
price: $320

A cluster of blocky habit Cinnabar crystals are perched on contrasting Dolomite. The main cluster looks like a single crystal but on close exam it is not, these are inter-grown and aligned much like a twin structure reaching 1.5 CM. Remarkably this is also perfectly damage free under good magnification . Flawless is rare in large Cinnabar as these are quite fragile. Sharp, glassy luster and excellent translucency, the Cinnabar glows a brilliant red if given any backlighting. At one time Chinese Cinnabars were rare classics, the world's best crystals, treasured, nearly priceless and only seen in major museums. That changed around 1990 and good specimens were for a while plentiful. Recently the main mines in Hunan Province have been shut down, these are already getting scarce.

Gypsum v. Selenite - twinned, classic
stock #15.1-1023- (CN353)
Eisleben, Mansfeld Basin
Saxony, Germany
12 x 4.9 x 4.2 CM (cabinet)
price: $750

Large and with textbook perfect form, this is a killer old German Selenite ex. Lazard Cahn, Charles Noll and others. Lazard Cahn (1865-1940) had a long and highly regarded career as a mineral collector and dealer. His label is vintage 1908-1940, the mine itself is even older, type locale for two species and a classic locale by any definition. The Gypsum is fully transparent, sharp and internal structures and clouds can be clearly seen inside. From some angles the internal structures seem to show a phantom but it is faint. The main crystal twin is doubly terminated and looks fine from any angle but the second photo shows the best view in my opinion.

Beryl var. Aquamarine with Schorl and Quartz
stock #15.1-448
Erongo Mountain, Karibib
Erongo Region, Namibia
4.2 x 3.2 x 3.6 CM (miniature)
price: $60

A cute Erongo combo specimen that has several doubly terminated Aquamarine crystals splayed on a mixed crystalline matrix. The Beryls have some transparency but overall they are a milky translucent. The Erongo Mountains have endless varieties of interesting minerals and produce enough volume that nice things can be found at any price point.

stock #12.1-097
Tamil Nadu, India
6.4 x 5.2 x 4.1 CM (cabinet)
price: $200

Deep vivid purple Amethyst in a flower form which is much more rounded or ball like than we usually see. From the amazing finds at Tamil Nadu, the Amethysts contrasts well with the matrix which includes several clusters of small Calcite crystals. The Calcite is fluorescent as well. No damage, and very three dimensional.

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.
