Rhodochrosite - large triangonal habit crystal
stock #24.1-185
Wutong Mine, Liubao, Cangwu Co. Wuzoh Pref.
Guangxi Province, China
6.7 x 5.4 x .7 CM (cabinet)
price: $990

Very sharp, complete with a rich color. a triangular form crystal that is in fine condition. This form of Rhodochrosite is quite uncommon and was best known in far smaller crystals from the famed Mont Saint-Hilaire. This is however a huge crystal from the 2005-6 finds in China from a limited zone that produced some large flat crystals. Unlike most in the find, this one is complete and undamaged on all the edges and seems to be a floater. Complex small steps and faces are noted on the flat sides and edges, probably the result of dissolution and re-crystallization cycles. Several localities worldwide do have flat habit Rhodochrosites which are very different from the scalenohedral and rhomb crystals that are more typical. However those specimens from most localities are not very distinct as to crystal form, they are rounded much like flat nearly circular disks. This is a very fine exception to the rule, a full sharp triangle.

Hemimorphite -exceptional bright blue botryoidal
stock #24.1-145
MFouati Mine, Bouenza Department
Bouenza Department, Republic of Congo (Brazzaville)
4.1 x 2.8 x 2.3 CM (miniature)
price: $350

Intense deep blue and with a wet-look luster, this is a very fine Hemimorphite from a recent find at the Mfouati Mine. This locality in the Republic of Congo has in the past 2 years offered a few fine surprises to the mineral world. We understand that nothing new is possible now as the ownership and management have changed there. That said this is a fine Hemimorphite from anyplace and as fine as any we have seen in this size.

Elbaite - conjoined dichroic gem crystals
stock #18.AX-019
Coronel Murta, Jequitinhonha Valley
Minas Gerais, Brazil
3.2 x 2.6 x 1. CM (thumbnail)
price: $250

A pair of terminated transparent Tourmalines from vintage 1980 finds at Coronel Murta (Minas Gerais, Brazil). This Elbaite is also quite dichroic and best appreciated when rotated in front of a polarized light like a computer screen. The color ranges from almost colorless blue hue to a very dark green. In very good condition overall, this is nearly all facet grade clear and has fine well-developed striations. 17.5 grams and quite different from more recent Brazilian Tourmalines. This will fit at an angle in a perky box but not a 1 inch cube.

Scheelite on Muscovite with Albite - Chinese classic
stock #6.2-481
Mt. Xuebaoding, Pingwu Co., Mianyang Pref.
Sichuan Province, China
6 x 5.7 x 2.7 CM x (cabinet)
price: $390

A fine, sharp and partly gemmy crystal of Scheelite perched and well-exposed on matrix. Bright luster and fine undamaged condition. The crystal is 3 CM across and the color ranges from orange to a straw yellow. From early finds on Mt Xuebaoding, a fine display quality specimen that is of a quality and style not seen in more recent finds.

Leucite - clustered twin crystals
stock #AX-35-101
Roccamonfina, Caserta Province
Campania, Italy
4.3 x 4.1 x 3.2 CM (miniature)
price: $80

Leucite is a mineral oddity in that it is classified as both a Feldspathoid and is listed in the Zeolite family as well. It has a crystal form very similar to Analcime. This cluster is in the typical habit and from a well-known Italian locality. Complete all around no damage.

Nagyagite - Gold Telluride with Rhodochrosite, historic
stock #21.1-202
Sacaramb, Deva
Hunedoara, Romania
7.3 x 4.8 x 5.1 CM (cabinet)
price: $1100

A large and rich specimen of Nagyagite with one face sawn and polished to show the structure. From the type locality this is a heavy mass of Gold Telluride in a mixed specie piece. Sizable masses of metallic Nagyagite are well-exposed on all sides, this specimen comes from the collection of the mineral museum at Pribram in the Czech Republic. This rare specie was named for the locality (Nagyag is the Hungarian name for this location in Romania). Although this is mostly a massive specimen there are some small crude crystals in vugs and crevices best seen with magnification. At 218 grams, there is certainly a lot of Gold in this piece it is remarkable that such rich ore was not smelted.

Lazurite crystal on Marble
stock #24.1-191
Sar-e Sang, Kuran wa Munjan District
Badakshan, Afghanistan
3.3 x 2.7 x 2.6 CM (thumbnail)
price: $110

A well-exposed and sharp crystal of Lazurite on contrasting white Marble matrix. It is hard to find such a good thumbnail of Lazurite, the crystals tend to be much too large. In fine condition, a choice classic specimen.

Hubnerite with Fluorite and Quartz
stock #22.1-607-(YL)
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
5.6 x 5.3 x 2.8 CM (cabinet)
price: $440

Very lustrous sharp Hubnerite crystals with good red highlights set on Quartz with purple Fluorites. A choice multi-specie specimen from the great Yaogangxian Mine. Hubnerite is much more rare from here than the similar Ferberite, and this is a well above average example of the specie. In excellent condition as seen, the crystals are nicely offset by the purple Fluorites, milky Quartz and with a dusting of Pyrite. Displays well, an excellent addition to a Yaogangxian suite or for a Chinese collection.
