Fluorite - water clear classic
stock #Alec-34-079
Walworth Quarry - Walworth, Wayne County
New York, United States
2.1 x 1.3 x .8 CM (thumbnail)
price: $400
Winter 2016-17

An ultra clear, very sharp pale blue Walworth NY Fluorite thumbnail. In fine condition and far better in person, these gemmy Fluorites are coveted US classics. This example is well above average and despite the small size has a lot of display impact. A small amount of Dolomite matrix is seen perfectly through the Fluorite and looking like inclusions. Collected over a decade ago, a few are found each year in this working quarry, but most are never seen on the market.
Scapolite (purple gem crystal)
stock #16.1-525
Sar-e-Sang District, Koksha Valley
Badakshan, Afganistan
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.
SOLD Anatase - Classic habit and locale
stock #SOLD 16.1-171
Geiteryggen, Ullensvang, Hardangervidda
Hordaland, Norway
3 x 2.3 x 1.5 CM (thumbnail)
price: $0
Winter 2016-17

A perfect Anatase crystal neatly perched on a contrasting crystallized Adularia matrix. Sharp and lustrous, the Anatase is 1.3 CM long and well exposed. This is classic material
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.
