Rhodochrosite on Fluorite with Goethite
stock #A-19-074
Uchucchacua Mine, Oyon Province
Lima Department, Peru
6.3 x 3.6 x 3.7 CM (cabinet)
price: $375
Winter 2016-17

A choice small Rhodo specimen with nice color and in fine condition. The matrix is a dark Goethite that is covered with tiny colorless Fluorite crystals that look black due to the matrix showing through. The Rhodos are mostly scalenohedral with truncated tips some of them showing some "wheat sheaf" habit. Good coverage as well makes this a nice display piece.
Azurite -bladed crystals altering to Malachite
stock #16.1-091
Khanong open pit, Sepon Mine, Vilabouly District
Savannakhet Province, Laos
4.2 x 3.1 x 2.8 CM (miniature)
price: $420
Winter 2016-17

A great new locality the Sepon mine in Laos has been producing a few unusual and very fine Azurites. This is a very distinctive specimen with electric blue bladed crystals standing free of the matrix. In perfect condition, some of the Azurites are zoned with a slight alteration to Malachite. Very lustrous and sharp, the matrix is a mix of malachite balls and spheres of slightly irridescent Goethite. An excellent, esthetic miniature.
Scapolite (purple gem crystal)
stock #16.1-525
Sar-e-Sang District, Koksha Valley
Badakshan, Afghanistan
2.6 x 2.4 x 2 CM (small miniature/ large thumbnail (toenail))
price: $600
Winter 2016-17

A deep, intense purple, very lustrous Scapolite crystal from Badakhshan Afghanistan. Tranparent to translucent and in very good condition this is a particularly choice small gem crystal. Classic habit for these rare crystals from Badakhshan, which are world class for the specie.
Cassiterite with Arsenopyrite and Muscovite -unusual locale
stock #Alec-12-135
Yaogangxian Tungsten Mine, Yizhang County
Hunan, China
3.6 x 3.5 x 2 CM (miniature)
price: $100
Winter 2016-17

A rare example of a Yaoganxian Cassiterite that is well crystallized. One of the most prolific mineral mines on Earth, Yaoganxian has produced many fine specimens of many species, but almost no Cassiterite. This small specimen is the best example we have seen. There are a few small Arsenopyrite crystals as well and this has some well defined twins. Compared with the world class Cassiterites from the famed Pingwu and Ximeng mines this is a modest piece, but for a Yaoganxian suite this is a killer.
Wulfenite on Mimetite
stock #15.1-970-(SM4923)
Ahumada Mine, Los Lamentos
Chihuahua, Mexico
9.8 x 7 x 4 CM (cabinet)
price: $590
Winter 2016-17

A very fine, attractive Bipyrimidal Wulfenite from Los Lamentos. This famed mine is best known for the tabular habit Wulfenites, but rarely this pointed habit was found, often on a dark green druze of tiny Mimetite crystals. Similar but noticably different from bipyrimidal Wulfs from Mina Ojuella. This specimen is esthetic, large, very colorful and in fine condition. A choice older Mexican classic Wulfenite.
Titanite with Adularia, Byssolite, Apatite etc.
stock #15.1-1054-(SM2740)
Grischun (Grisons)
Graubunden, Switzerland
10.5 x 6.5 x 3.9 CM (cabinet)
price: $600
Winter 2016-17

An old Swiss classic Alpine specimen. Complexly structured matrix hosts several minerals in layers with gemmy green Titanites on the top. Beds of Bysollite needles have well crystallized Adularia protruding and micro sprays of Apatite throughout. This displays the complex nature of mineralization in Alpine clefts very well. The Titanites crystals are up to 1 CM though most are smaller. Ex Charles M. Noll and Jim Dufoe collections.
Agate Ps after Aragonite
stock #15.1-1058- (SM598)
Rancho Coyamito, Sierra del Gallego, Mun. de Ahumada
Chihuahua, Mexico
10.1 x 7.6 x 5 CM (cabinet)
price: $380
Winter 2016-17

A really fine Pseudomorph with a purplish Agate (chalcedony) that has completely replaced a cluster of Aragonite crystals. The hexagonal form of the Aragonite is perfectly preserved. Esthetic, in fine condition damagewise and a a small bonus this is also a natural rattle since a hollow crystal has some trapped material inside. Great form and nice color too.
Dioptase (well crystallized for type locality)
stock #15.1-945- (SM1939)
Altyn-Tyube, Kirghiz Steppes
Karagandy Province, Kazakhstan
6.8 x 4.5 x 4.6 CM (cabinet)
price: $690
Winter 2016-17

A bright, striking Dioptase with sizable, perfect emerald green crystals on a etched matrix. From Altyn-Tyube, this is of exceptional quality for that location, and in fact is a choice specimen from anyplace else too. Sharp perfect crystals to 1.3 CM long are clustered in a sizable mass, a few micro tufts of Malachite are also note. Most Altyn-Tyube pieces have much less visual impact.
