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 #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


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.

SOLD Apatite (Fluorapatite in unusual form)
stock #SOLD 6.1-245
Golconda Pegmatite district, Govenador Valadares
Minas Gerais, Brazil
4.1 x 1.6 x 1.3 CM (miniature)
price: $0


A strange form for this unusual gemmy pink Apatite from Golconda. This is a complete floater with no matrix or points of attachment, and no damage either. The crystal is curved and tapered with twisting evident as well. Certainly odd and far from typical, there is also a fadden-like inclusion running the length of the crystal clearly seen with any backlighting.

Kobyashevite with Selenite on Calcite
stock #18.1-535
Mina Ojuela, Mapimi
Durango, Mexico
6.5 x 5.1 x 3.9 CM (cabinet)
price: $800


The rare coper mineral Kobyashevite was discovered and described in 2011. A close relative of Devilline this Copper Sulfate specie was an exciting find at Mina Ojuela this year, and in this deposit the specimens are impressively large and attractive, certainly the worlds best. It seems that these specimens are postmining redepositions and are always partly overgrown with small needles of clear Selenite. The best examples have a rich blue-green or Turquoise color and when this is deposited on calcite crystals these have a very esthetic presentation. This specimen is in excellent condition and is the most attractive I have seen from the find. A choice and colorful rarity.

Descloizite -stacked
stock #16.1-635
Berg Aukus, Grootfontein District
Otjozondjupa Region, Namibia
5.3 x 2.4 x 1.4 CM (small cabinet/ large miniature)
price: $440


A lustrous, flattened crystal tree or leaf-like structure of oriented Descloizite crystals in super condition. A textbook example of epitaxial arrangement or stacking. The individual crystals are a dark red color in strong light but in normal light they look black to metallic silvery. The crystals are undamaged, some are also transparent. Great form and sparkling luster, these fine Berg Aukus specimens have become rare in this quality. The Descloizites from this closed mine are regarded as the best ever found and are modern classics.

Fluorite -enclosing Shorl
stock #18.1-592
Erongo Mountain, Karibib
Erongo Region, Namibia
3.5 x 3.4 x 2.4 CM (small miniature/ large thumbnail (toenail))
price: $320


The Erongo Mountains sometimes produce some very exotic and amazing Fluorites. This is an excellent example with stacked "melted look" crystals completely enclosing crystals and sprays of Schorl. The Fluorites are all Spinel twinned, the highly etched surface gives an unusual look and the whole piece is simply bizarre. In fine condition a neat small miniature.

Dolomite cast with two generations
stock #16.1-305
Tsumeb
Otjikoto Region, Namibia
6.5 x 3.8 x 2.8 CM (cabinet)
price: $190


A delicate and fine Dolomite cast having two separate generations. The large scalenohedral shapes are hollow having just a thin skin of Dolomite that had covered what were likely Calcites, now long gone. The matrix is an earlier generation itself just a thin skin of tiny sparkling crystals. The Dolomite casts from Tsumeb were found in many exotic forms are are very collectable. This one is in perfect condition, esthetic and looks fine from all sides.

Fluorite -dark zoned
stock #14.1-415
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
4.1 x 3.3 x 2.5 CM (miniature)
price: $350


very sharp single cube perched on a shard of matrix, mostly Muscovite. The Fluorite has very deep purple zones and masses on the outer edges the center core is transparent and a light blue color. Very glassy luster as in all the better Yaoganxian Fluorites. The display side is perfect damage wise, there is contacting and cleaves on the back. Better in person, this is from mining in the 2004-5 season when a very rich area was worked. The locality no longer produces anything like this.
