Dioptase very large crystal
3.1 x 1.3 x 1.2 CM (small miniature/ large thumbnail (toenail))
A fine large single prism composed of two main parallel crystals that are joining in a single shared termination. Super lustrous with brilliant color, in fine overall condition. The base has a few tiny adhering crystals that are not complete and it is possible to see the break where this was removed from the host mass of Dioptase where this grew. Aside from the matrix the main large crystal is in perfect undamaged condition. From finds a few years ago in the Kaokoveld, large prisms like this were just not known from other locations. A choice example of this find
3.4 x 2.4 x 1.5 CM (small miniature/ large thumbnail (toenail))
A super clean, brilliant toenail sized Dioptase from finds at Kaokoveld in 2012. Very sharp and lustrous crystals in excellent condition and having an esthetic arrangement. While Dioptase is known from quite a few localities in the world but this sort of very fine specimen is from either Tsumeb (closed forever) or Kaokoveld, bot being in Namibia. Top emerald green color with transparent areas set this apart, better in person.

Late Summer 2018
Fantastic Copper species piece with Emerald green Dioptase crystals on royal blue Shattuckite. The Dioptase are highly lustrous, sharp and up to 1 CM. The underlying Quartz matrix is very solid and there are few hints of Malachite at the edges. These were found a few years ago in a one time find in the Kaokoveld, and sold very quickly. Happy to be able to offer this one again. The color contrast on this is especially fine.
Super colorful multi-specie specimen from Tsumeb. In fine condition with excellent luster and sparkle throughout. The Calcite rhombs are dusted with micro crystals of Dioptase which gives a sugar cube texture but with emerald green color. Very good display impact in person.

Deep green Dioptase crystals is selectively deposited on milky white Calcite rhombs in an attractive arrangement. The contrast is very distinctive and a classic Tsumeb habit. In fine condition, this is a choice yet affordable specimen from this iconic locale
A bright, striking Dioptase with sizable, perfect emerald green crystals on a etched matrix. From Altyn-Tyube, this is of exceptional quality for that location, and in fact is a choice specimen from anyplace else too. Sharp perfect crystals to 1.3 CM long are clustered in a sizable mass, a few micro tufts of Malachite are also note. Most Altyn-Tyube pieces have much less visual impact.

Democratic Republic of Congo (Zaire)
3.8 x 2 x 1 CM (miniature)
A large slender Dioptase crystal stands a full 3.3 CM tall on a contrasting matrix. The matrix is small gemmy quartz crystals that are clear enough to see the color of the host rock below, likely a Cuprite rich matrix. The Dioptase is brilliant in color, with glass-like luster. One side has a jagged contact that shows some micro crystals overgrowing on it. This has esthetics that stand out and there is no chipping or damage even with 20X magnification.

The classic Tsumeb combination of emerald green Dioptase with snow white Calcite in an esthetic composition. The Dioptase is bright and glassy reaching 1.7 CM in size. There is some contact/damage on the backside but the display face is in fine condition. No other Dioptase from anywhere has the same look as these old Tsumeb specimens.
