I surprised Tucson early 2017 new dioptase old locality apparently
Kimbedi, Mindouli District, Pool, Republic of Congo (Brazzaville)
Miniature, 4.3 x 2.6 x 2.3 cm
I was surprised at Tucson in early 2017 to see a new find of dioptase from a very old locality apparently known during the old French era, but not productive since. Not only was this a new source for dioptase, but the small pocket produced has crystals with a satiny luster, sharp form, and superb color that makes them rival the best of Tsumeb in quality! They are fairly translucent, and have a shi... Read more

Even historical localities Tsumeb Russia elongated dioptase crystals
Christoph Mine, Kaokoveld Plateau, Kunene Region, Namibia
Small Cabinet, 6.0 x 3.5 x 3.0 cm
Even after all the other historical localities (Tsumeb, Russia, etc.), there is still something about these elongated dioptase crystals from modern finds in Northern Namibia by Charlie Key (keyite, ludlockite, and the Indiana Jones of mineral collecting in Southern Africa) and his mining team that blows me away - and this is among the largest crystals found, with a superb, pristine, nearly 4 cm cr...

Quartz included Dioptase rare nature known small handful localities
Christoph Mine, Kaokoveld, Namibia
Cabinet, 11.9 x 10.2 x 9.1 cm
Quartz included with Dioptase is very rare in nature, known only from a small handful of localities. This monster is the largest complete crystal I have seen, and is chock-filled with inclusions of brilliant green dioptase! It is 895 grams, and complete all around. One side is completely carpeted by a surface sparkle, ingrown into the surface. Other faces show the inclusions. In person, it is glo... Read more
Splendid colorful display appearance choice Dioptase Calcite small cab
Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia
Small Cabinet, 6.7 x 4.9 x 1.7 cm
Splendid and colorful in display appearance, this choice Dioptase on Calcite small cab from Tsumeb has great aesthetics. Not only are the Dioptase crystals gemmy, lustrous, and a beautiful emerald green, and the Calcite rhombs even more gemmy, but they all rest on a heart-shaped matrix. A little duftite decorates the calcites, for multiple green color contrast, here... a nice touch! And if a speci... Read more
A colorful combination piece featuring super lustrous Dioptase
Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia
Small Cabinet, 7.0 x 5.9 x 5.1 cm
A very colorful combination piece featuring super-lustrous Dioptase crystals on Calcite. The color saturation, as well as the gemminess, of the Dioptases is terrific, and far better than the pics can adequately portray. There are even several balls of primary Malachite that add greatly to the aesthetics, as well as the mineral interest. And of course, the carbonates below fluoresce. Classic Tsumeb... Read more
Very good classic Tsumeb combo Dioptase Calcite Both species
Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia
Miniature, 5.6 x 4.4 x 4.2 cm
Very good, classic Tsumeb combo of Dioptase on Calcite. Both species are well-crystallized and all average about 2 mm in size. The Calcite is fluorescent. For it's richness and size (large miniature/small cab borderline in class), this is a choice specimen of this desirable combination! It is sparkly and leaps off a shelf in a way hard to capture... dioptase is notoriously difficult to photograph ... Read more
Dioptase Calcite attractive desirable Tsumeb combinations These
Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia
Small Cabinet, 8.3 x 7.3 x 2.5 cm
Dioptase on Calcite is one of the most attractive and desirable of all the Tsumeb combinations. These Dioptases are gemmy, a rich emerald green, and super lustrous. Much more so than the pics can portray, in fact. The largest of these crystals just reaches 1 cm, and they all rest on a bed of gemmy Calcite rhombs that average 2-3 mm. Both generations of Calcite are fluorescent. Tsumeb, of course, i... Read more
Beautiful deep green crust mm size Dioptase crystals matrix
Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia
Small Cabinet, 5.7 x 4.5 x 2.1 cm
Beautiful, deep green crust of mm-size Dioptase crystals, on matrix of what might be conichalcite or perhaps duftite (not analyzed). The luster on these crystals is so good, and the color so rich, that this really looks like a piece of glimmering art glass with the sparkly micros atop, contrasting to the matte olive green underneath and showing a mix of color as a result...A really scintillating a...

A gorgeous colorful Tsumeb large miniature technically small cab size
Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia
Miniature, 5.6 x 3.2 x 2.8 cm
A gorgeous and colorful Tsumeb large miniature (only technically a small cab size) with two generations of Dioptase covering a fluorescent Calcite matrix. The second generation of larger, lustrous, gemmy Dioptase crystals up to 1.3 cm rests upon a bed of GEMMY, mm-size Dioptases. The piece shimmers and sparkles like green sugar candy, and is ten times better in person than the pics can portray. On... Read more
