Cobaltoan Calcite and Malachite
stock #18-AX-12-019
Mashamba West Mine, Kolwezi, Katanga Copper Crescent
Katanga (Shaba), Democratic Republic of Congo (Zaire)
6 x 4.4 x 4.2 CM (cabinet)
price: $640


The Cobaltoan Calcites of Mashamba have been gone for more than a decade now, but they are still considered to be some of the best and most intensely colored ever found. This specimen has the most desirable contrast with a small matrix of green Malachite and has several generations of pink to clear Calcite displayed. Sadly there are some edge cleaves or contacts but the overall specimen condition is very good and still displays well. The best Scalenohedral crystals are remarkably clean and free of chipping. There are several possible display angles. Now very hard to get in the mineral market these are unique and quite sought after.
Axinite with Quartz and Calcite
stock #9AE-1077
Nandan, Hechi Prefecture
Guangxi, China
6.5 x 4.3 x 2.4 CM (cabinet)
price: $260


Well defined, sharp Axinite crystals from a find over 10 years ago in the little known mines of Nandan. At the time these were the first Axinites found in China and as far as I know are still the only good quality specimens found so far. No damage but a few contacts are noted, the crystals are free standing and reach over 1.5 CM.
Cuprite on Dickite
stock #16.1-639
Milpillas Mine, Cuitaca, Municipio de Santa Cruz
Sonora, Mexico
7.1 x 2.9 x 2.5 CM (cabinet)
price: $650


A shard of breccia bedrock is thickly covered with white Dickite that holds clusters of sharp bright red Cuprite crystals. The Milpillas mine is world famed for its great Azurites but several other Copper species are also first rate at this mine. The Cuprite on this piece is epitaxially oriented and has clean dark red color with bright luster. The individual crystals are sharp and damage free, all are transparent and could be faceted. Well above average quality for the find, the crystals are3 complete, well formed sharp and have classic form, unlike the flattened and distorted Cuprites that are more typical from here. Not just a locality piece, this is a choice displayable specimen that is impressive in person.
Sphalerite - "Stalactitic" crystal chain
stock #16.1-175
Dalnegorsk, Kavalerovo Mining District
Primorsky Kray, Far Eastern Region, Russia
5.7 x 1.5 x 1.2 CM (cabinet)
price: $360


A super exotic, rare habit for Sphalerite to be in a column. Often called Stalactitic (not technically correct as there is no sign of a hollow central canal) these are very rare and the crystals are aligned in a remarkable way. In fine undamaged condition and with mirror bright luster, in person a slight twist can be seen as well. Choice and a modern classic from the great Dalnegorsk.
Agate (Laguna) polished nodule
stock #18.1-596
Ojo Laguna, Estacion Ojo Laguna, Municipio de Ahumada
Chihuahua, Mexico
4.2 x 4 x 1.2 CM (miniature)
price: $280


Laguna Agates are unique in their colors and distinctive patterns. These are highly prized and usually very expensive in larger sizes. This smaller sized specimen is from an older find several decades ago, and has vivid intense color contrast. Such perfect form and color pallet in a larger cabinet size would be a solid 4 figure specimen. A great value for a reasonably priced but perfectly beautiful nodule.
Agate (Laguna) nodule
stock #18.1-597
Ojo Laguna, Estacion Ojo Laguna, Municipio de Ahumada
Chihuahua, Mexico
4.4 x 2.2 x 1.3 CM (miniature)
price: $150


Laguna Agates are unique in their colors and distinctive patterns. These are highly prized and often very expensive in larger sizes. This smaller sized specimen is from an older find several decades ago, and has vivid intense color contrast. Such perfect form (with intact edges and rind) showing such a color pallet in a larger cabinet size would be a solid 4 figure specimen. A great value for a reasonably priced but perfectly beautiful nodule.
Agate (Laguna) Polished Nodule
stock #18.1-598
Ojo Laguna, Estacion Ojo Laguna, Municipio de Ahumada
Chihuahua, Mexico
5.2 x 4 x 1.3 CM (miniature)
price: $210


Laguna Agates are unique in their colors and distinctive patterns. These are highly prized and usually very expensive in larger sizes. This smaller sized specimen is from an older find several decades ago, and has vivid intense color contrast. Such perfect form and color pallet in a larger cabinet size would be many times this price. A great value for a reasonably priced but perfectly beautiful nodule.
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


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.
