Elbaite - Cats-eye Toumaline
stock #18-AX-7-540
Virgem do Lapa
Minas Gerais, Brazil
9.1 x 2.8 x 1.7 CM (cabinet)
price: $775


Silky "catseye" luster in these bicolor crystals makes a complex but impressive cluster. Most every crystal in this specimen is doubly terminated with one end pointed the other a flat basal termination. In impressive condition this is an older (25 years plus) Brazilian gem. The darkest colored areas are mostly opaque but the majority of the prisms are translucent and on thin edges transparent. With backlighting the crystals all show several areas of zoning, but in normal display these seem to have two main zones and silky texture is pronounced. Most of the faces have many tiny accicular crystals attached at jumbled angles, adding a nice sparkle in person. The longest crystal in this cluster is 8.5 CM. An excellent example of this style and habit not often available.
Topaz- Imperial gem
stock #16.1-162
Ouro Preto
Minas Gerais, Brazil
7.3 x 1.9 x 1.5 CM (cabinet)
price: $1400


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)
stock #7AE-353
Merelani, Umba Valley, Lelatama Mountains, Arusha Region
Manyara Region, Tanzania
2.2 x 1.4 x 1.1 CM (thumbnail)
price: $350


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
SOLD Cuprosklowdowskite with Torbernite, Vandenbrandeite
stock #SOLD 10-AX-30-045
Musonoi Mine, Kolwezi, Western area
Katanga (Shaba), Democratic Republic of Congo (Zaire)
7.6 x 6.2 x 4.8 CM (cabinet)
price: $0


One of the most colorful and attractive of the Uranium minerals, the Copper rich version of Sklowdowskite. This one has the brilliant green needle crystals protected in a vug. The associated species are best seen with magnification but do add some contrast and color. From the famed mine of Musonoi in the Katanga Copper region that produced what are certainly the best examples of the specie more than 20 years ago, this is a good example that will not break the bank.
Enargite -Classic locale
stock #16.1-601
Leonard Mine, 3800 foot level, Butte
Montana, United States
5.2 x 4.8 x 3.9 CM (small cabinet/ large miniature)
price: $380


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.
Cerussite - blue-green inclusions
stock #18AX-29-114
Mina Ojuela, Mapimi
Durango, Mexico
6.8 x 4.4 x 4.2 CM (cabinet)
price: $490


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.
Calcite - unusual habits with Clinochlore
stock #15.1-589
Nikolaevskly Mine Dal'negorsk
Primorsky Kray, Far Eastern Region, Russia
8.2 x 4.4 x 4.3 CM (cabinet)
price: $350


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.
Diopside- Chromian green with Grossular
stock #18.1-741
Orford Nickel Mine, Brompton Lake, Sherbrooke
Quebec, Canada
5.9 x 4.4 x 4.2 CM (cabinet)
price: $375


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.
