Topaz- Imperial gem
7.3 x 1.9 x 1.5 CM (cabinet)
A sizable and fine elongated imperial Topaz from Ouro Preto with classic bright orange color. In person this is fully transparent and has glassy luster, a perfect pyramidal top termination and a more crude lower termination (doubly terminated) a chip is on the lower corner where this was removed it is not seen on most logical display angles, A contact along one edge is completely healed and recrystallized, overall this is in remarkably fine condition for such a large crystal. Wispy dark inclusions are noted and in the center of the crystal is the nice rose color that is especially desirable. Choice and better in person too.
Tanzanite (gem blue Zoisite)
Merelani, Umba Valley, Lelatama Mountains, Arusha Region
2.2 x 1.4 x 1.1 CM (thumbnail)
A Tanzanite crystal with excellent color change. This is well terminated, glassy deep blue to purple crystal in good condition. The tip of the termination is especially transparent and shows a nice blue "cloud" inside. The backside of the crystal shows a more complex area that has stepped faces and is likely a recrystallized contact. A nice specimen of the specie that is reasonably priced
Enargite -Classic locale
Leonard Mine, 3800 foot level, Butte
5.2 x 4.8 x 3.9 CM (small cabinet/ large miniature)
A cluster of unusually bright, lustrous and sharp Enargite crystals with a few small Pyrite and Quartz on the edges. In excellent undamaged condition with Enargites free standing up to 1.7 CM. A choice, classic Leonard Mine (Butte, Montana) specimen from the golden age of mining there. The flashy luster on this black Copper Sulphide is quite esthetic (and even attractive for a black mineral)compared with the more usual sooty black specimens.
An incredible Ojuela Cerussite that is a mix of colorless, green and nearly black Cerussite crystals with minimal matrix of Sulfides, mostly Pyrite. From a find about 5 years ago there were not many as fine as this. Slender, flattened and blocky prismatic habits with and without twinning in exceptional condition. The quality is amazing for this delicate mineral. The darkest Cerussites are included by a dark Sulfide, probably Galena. The green-blue color is an especially nice touch when seen on the clearest crystals. This could be trimmed to a killer miniature but the overall specimen seems to have greater mineralogical interest if kept intact.
A complex older Dalngorsk specimen that displays very well from several angles. These Calcites are gemmy clear and some have sharp mushroom like caps on the terminations of Scalenohedrons. The face details and ice-like etching makes these especially impressive in person. In excellent condition as seen, this is not anything typical and certainly a great addition for any Calcite collection or Dalngorsk suite.
The so called Chromian Diopsides from the famed Orford Nickel mine are quite prized. We are told that the color may be due to Nickel and not Chrome but either way these are very attractive and uncommon. This one has unusually fine apple green hue. The largest crystal is 1.7 CM and all are gemmy with very glassy luster. Normally the larger crystals are opaque, and a yellowish to grey color. Such bright green clear crystals are usually only microscopic. Tiny deep green Grossular are also present as are Calcite crystals. The tiny crystals add a lot of sparkle in person.
Pink Fluorite crystal with fine clarity, light frosting and distinctive form. No damage, the Fluorite is nestled among sharp Muscovite crystals and is well protected. The habit is a highly modified octahedron with complexity that adds to visual interest. A 1.5 CM gem clear Fluorite that is better in person. A really good example of Pakistani pink alpine Fluorite that will not break the bank.
Muqiaomian Depsit, Xinlu-Shuilyanba Quanzhou County, Guilin Prefecture
Guangxi Autonomous Region,
5.6 x 4.5 x 3.3 CM (cabinet)
From the one time find over a decade ago that produced some of the worlds best ever Hydrozincites. This is a very well formed example with perfect form and fine luster. Hydrozincite is not normally thought of as an esthetic mineral but this is certainly very attractive. These were at first mistaken for Aragonite with odd luster but on closer study proved to be much rarer and with amazing quality. We have not seen any like this for sale in years.
