Calcite balls with Quartz and Actinolite
stock #16.1-177
Huanggang Mine, Chifeng Prefecture, Hexigten Banner, Ulanhead League
Inner Mongolia Region, China
7.2 x 5.5 x 3 CM (cabinet)
price: $190
Dec 2018

A remarkable and strange Calcite formed of spherical clusters of flat crystals. The balls are connected in a chain and these are covered with bright sparkling Quartz in tiny doubly terminated clear crystals much like Herkimer Diamonds. A scattering of Hairlike Actinolite crystals are seen with magnification impaling both the Quartz and Calcite. Choice and in excellent condition, the esthetics are impressive. Another of the mineral wonders from the incredible deposits at Huangang.
Cerussite on Azurite
stock #AX-27-086
Poteryaevskoe Mine, Rubtsovskoe Cu-Zn-Pb deposit, Rudnyl Altai
Altaiskii Krai, Russia
5.2 x 3.3 x 2.5 CM (cabinet)
price: $725
Dec 2018

The fantastic finds of Cuprites at Rubtsovskoe was huge news a few years ago, and made the region famous. Recently some very attractive Azurites have turned up but only a few associated with Cerussite. This example has a reticulated cluster well placed on contrasting crystallized Azurite. Excellent color and form, a fine addition to any copper suite and will fit well with the Cuprites and coppers that are so well known from here.
Cobaltoan Calcite and Malachite
stock #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
Dec 2018

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 #9.AE-1077
Nandan, Hechi Prefecture
Guangxi Autonomous Region, China
6.5 x 4.3 x 2.4 CM (cabinet)
price: $260
Dec 2018

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.
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
Dec 2018

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
Dec 2018

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
Dec 2018

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 #AX-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.
