EMERALD7 - Beryl Var. Emerald
$ 795.00 SOLD NET
Muzo Mine, Muzo, Vasquez-Yacopi Mining District, Boyaca Department, Colombia
miniature - 3.8 x 2.4 x 2.7 cm
The Emerald crystal is 9mm wide by 7mm tall by approx. 9mm deep. It's very bright green, and the crystal is deep into the matrix, so the color is rich and it pulls you into it. There must be a carat+ stone easy if you faceted it. It's well terminated and really pops from across the room. A classic columbian emerald. It comes mounted on an 1` 1/2" acrylic base.

DANBURITE6 - Danburite rough and cut
$ 375.00 NET
San Luis Potosi, Mexico
small cabinet - 5.5 x 2.5 x 1.9 cm
Danburite is found in a Tin Mine in Mexico. The miners that bring them out are apparently quite rough with them, as 98% of all the crystals are dinged. The crystal's termination is pristine, overall it is in good shape. It is roughly thumb size. It has a light pink cast to it.
The stone was faceted by Michael Davis, a well known american cutter. It weighs over 12.5 carats, it is a clean (flawless) stone that is extraordinarily bright due to its emerald cushion cut, and the fact that Danburite has a higher refractory index than diamond. I find good danburite rough once every few years, then I give it to Mike to cut beautiful stones. I then find a matching crystal that is in good condition. The stone would retail for between $40 and $60 per carat ($625 value).

Aruscuai, Minas Gerais, Brazil
cabinet - 11.5 x 4.25 x 4 cm
This quartz is very bright and lustrous. The termination is totally sharp and free of damage. It has a contact in the back, which actually creates interesting relief inside the crystal when you look at it head-on. It's a light citrinewith an interesting form in great condition.

SMITHSONITE3 - Cobaltoan Smithsonite
$ 3950.00 SOLD NET
Tsumeb mine, Tsumeb, Namibia
cabinet - 12 x 8 x 6.5 cm
This gorgeous Smithsonite has sensational color. Some Cobaltoan Smithsonites are a light or pasty pinkish color. This large specimen exhibits rich pink color, as you might see from Cobaltoan calcite from Morocco or an excellent rose quartz. The crystal sizes range up to 1 cm long. They have great luster, and they are ascetically positioned on the matrix. Actually the way it sits, it appears to be a rosey gem-crystal studded cave (or doorway) going into the piece (first pic), as you look to the left of it, it is thickly covered in pink smithsonite (pic 2). The only noticeable damage, if you can call it that, is easily seen in the first pic, near the bottom, there is a spot where the underlying matrix shows through (it was probably contacting the host rock in the pocket) It is a large piece measuring nearly 5 inches vertically, it weighs 594 grams (1 1/4 pounds). A fine example from the closed Tsumeb Mine.
