Fluorite on Quartz
stock #19.1-860
Riemvasmaak, Kakamas district
Northern Cape Province, South Africa
5.5 x 3.8 x 3.2 CM (cabinet)
price: $180


A milky Quartz with a subtle phantom is a the matrix for a mass of sharp zoned Fluorite crystals. These Fluorite cubes have a blue to purple edging and white to yellow cores. This locality (Riemvasmaak) has been a well known locality for fine green octahedral Fluorites but this style and habit are far more rare. Esthetic and in very good condition, the Fluorites are about 3 mm in size. An attractive and unusual specimen, the Fluorites cover three of the faces of the Quartz, the remaining 3 faces are empty.
Thaumasite
stock #19.1-422
N'Chwanning II Mine, Kalahari Manganese Filed
Northern Cape Province, South Africa
3.1 x 2.6 x 2.1 CM (thumbnail)
price: $650


A sharp and very choice thumbnail of Thaumasite crystals on matrix in excellent condition. The crystals all have a pale color and are transparent with a slightly milky look at some angles. The largest prism is just under 2 CM long. No damage. The best of this uncommon specie was found a few years ago at NChwanning, and those are now quite scarce. This piece is from that find.
Rhodochrosite- gem clear Rhomb
stock #19.1-351
Black Rock Mine, Black Rock District, Kalahari Manganese Field
Northern Cape Province, South Africa
1.4 x .6 x .3 CM (thumbnail)
price: $340


Small yet very vivid red and super transparent, a colorful gem crystal. , Sharp and perfectly terminated (these almost always have tiny tip cleaves) a very cute Rhodochrosite from the Kalahari. From the Black Rock mine, this is an older collection piece as these were found decades ago, before the big discoveries at NChwanning. Perfect clarity and a choice thumbnail.
Olmeite
stock #19.1-237
N'chwaning Mine, Kalahari Fields, Kuruman
Northern Cape Province, South Africa
3.8 x 3.4 x 2.2 CM (small miniature/ large thumbnail (toenail))
price: $90
Spring 2019

A cute specimen of Olmiite crystals in spherical form on contrasting matrix. Nice luster and fair pink color, these were once all labeled as Poldervartites (a rare mineral at the time of the find) later re-studied and classified as Olmiite (also at that time a rare mineral). This discovery was sizable and enough good specimens found to allow collectors to own a nice piece without major financial pain. In good condition and a good value.
Rhodochrosite -Scalenohedral form, Classic locale
stock #18.1-668
N'chwaning Mine, Kalahari Fields, Kuruman
Northern Cape Province, South Africa
1.7 x 1.5 x 1 CM (thumbnail)
price: $800
Spring 2019

A transparent gem crystal of bright red Rhodo from the classic N Chwanning #1 mine. This is part of a small find made late last year, the result of years of digging in an attempt to find more of the legendary scalenohedral Rhodos last found over thirty years ago. Those are now some of the most highly prized mineral specimens in the world. This new find was small as were most of the specimens, but the quality was excellent. The Rhodo crystals are perfect, lustrous and with top intense red. This specimen has a series of face modifications not seen in older materials. Condition is perfect, very few of the old find were so completely undamaged. Big display impact for the small size.

Dec 2018

A choice and brilliant thumbnail of complex, gem grade Rhodochrosite. This is part of a small find made late last year at the famed Nchwaning #1 mine. The result of years of digging in an attempt to find more of the legendary scalenohedral gem clear Rhodos last produced over thirty years ago. Those are now some of the most highly prized mineral specimens in the world. This new find was small but the quality was excellent. The Rhodo crystals are small but perfect, lustrous and with top intense red. This specimen has a mix of habits and forms all with a luster that is almost impossibly bright, best appreciated in person. A few tiny Hematite crystals are scattered on the piece as well otherwise this is all pure gem Rhodochrosite. We had the opportunity to select a few of the very best pieces from the find as they were unveiled at the Munich show, this is one of them.

Gaudefroyite
stock #18AX-14-387
Wessels Mine, Hotazel, Northern Kalahari Mn Fields
Northern Cape Province, South Africa
1.7 x 1.1 x .7 CM (thumbnail)
price: $475
Dec 2018

A top killer thumbnail of Gaudefroyite, the rare manganese mineral only known in decent crystals from a few places, all in the Kalaharie Manganese fields. This specimen is a stellar example with textbook form, sharp edges and bright luster. This is a large (for the specie) main crystal with a few smaller crystals on the base, and the prism has none of the crudeness or dull faces usually seen. Superb specimen of a usually unattractive rare, black mineral.
