Native Silver (crystals)
stock #7 MEX 204
Municipio de Fresnillo
Zacatecas, Mexico
5.5 x 2 CM (miniature)
price: $900


A fantastic, branching array of sharp spinel twin Silver crystals in perfect condition. This piece has some mysteries however. It was one of 3 pieces from Fresnillo in a collection assembled in the 70's, and aquired in the last owners collection in 1980. Some knowledgeable collectors have have questioned this location. Some think it's a very old Fresnillo piece, but not typical, but most likely a Zacatecas specimen. The other pieces in the group were more typical Fresnillo Silver this one being much more sharply crystallized. The question was asked if this is could be a lab grown crystal, as it is more perfect than most Mexican silvers. On investigation, it seems to be quite real, based on others experience and examining known fakes. I can not be 100% certain, so this is offered simply as very esthetic, well crystallized piece with questions about provenance. This is priced accordingly, and certainly well below market for this quality.
Smoky Quartz (alpine gemmy)
stock #8.DK-134
Tujetsch, Vorderhien Valley
Grischun (Grisons), Switzerland
4.4X1.6 CM (miniature)
price: $140


Gem clear, sharp and clean is what everyone looks for in a Swiss quartz. This is a fine small example with the lovely red brown color that makes these so distinctive. While this could be sold as a perfect example, 10x magnification and strong lighting can find some very tiny chips, so this is just "near perfect". Still an excellent small alpine crystal reasonably priced.
Topaz (Imperial gem)
stock #8DK-150
Ouro Preto
Minas Gerais, Brazil
5 x 1.9 x 1.2 CM (miniature)
price: $480


A classic, rich orange yellow crystal with great form, color lustre and condition. The Ouro Preto topaz is unlike any other in the world. This example is sizable and in much better condition than most, the base and lower shaft have some damage from collecting, most of the rest is very clean except some micro nicks to be found on close examination, What may look like chipping in the photos is all internal reflections of veils inside. Very good value for one of these in this size!
Spinel (twinned) w. ruby color
stock #8DK-127
Luc Yen
Yen Bai Province, Vietnam
2.5 X 2 CM (thumbnail)
price: $175


Deep red Spinel (spinel twinned) with good sharrp form, A very eyecatching thumnail, that is not quite a true gemmy transparency but is translucent on the edges. The color of this one is far better than most and the form is distinctive. Attractively priced too.
Proustite
stock #7-MOR-210
Bou Azzer District, Tazenakht, Ouarzazate Province
Souss- Massa- Draa Region, Morocco
6.5 x 5.8 CM (small cabinet/ large miniature)
price: $860


A very rich, estheticly presented and fine specimen of the rarest of the Ruby Silver minerals, Proustite. A large 4.6 CM crystalized mass of nearly pure proustite in association with minor acanthite crystals rises from the matrix. There is no visible damage even under 10x magnification. The individual proustites are brilliant ruby color, lustrous and well formed up to 3 mm in size and arranged on clusters. A great piece that shows the specie well from a great Silver locality, While this is not going to compete with the best old German and Chilean examples, it is affordable and pretty. This is one of the best I have seen from Morocco, likely from the Imiter Mine but I can not confirm the locality beyond the Bou Azzer region.
Calcite with Realgar inclusions
stock #6.2-066
Shimen (Jiepiayu) Mine, Shimen County, Changde Prefecture
Hunan, China
11x7x4CM (cabinet)
price: $3500


Simply incredible! A brilliant red cluster of calcite on matrix with small realgar crystals. Killer esthetics. We obtained this at the mine in 2003 and sold it shortly after- it was the best of the find. Since then we have not seen anything like this. We are pleased to have it back again for resale, The largest calcite crystal is 7.2 CM, and the piece displays well from multiple angles, but it does have a cleave on the backside. The red color on the calcite is from both a coating and inclusions that is primarily realgar, some recent analysis of similar materials have fund trace amounts of some rare rsenic minerals, this one has not been tested for those. Really striking color, the display side has no noticable damage. This will really jump out of any calcite display!
