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.
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.
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.
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.
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.
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.
Adularia - Classic alpine Manebach twin w. iridescence
stock #15.1-933-(SM2772)
St Gotthard, Central St. Gotthard Massif, Leventina
Ticino, Switzerland
8.3 x 5.1 x 3.8 CM (cabinet)
price: $385
Winter 2016-17

A large and fine old Swiss Orthoclase crystal that is a well formed Manebach twin with fine edge striations. Several older labels included date this back to the 19th century. This Adularia is very large, translucent to transparent and with textbook perfect form. From just the right angle the fine striations make an interesting display of diffraction colors and shows a rich iridescence. Classic and impressive.
Beryl V. Aquamarine with Quartz and Schorl
stock #16.1-321
Erongo mountain, Usakos and Omaruru districts
Erongo region, Namibia
5.2 x 5 x 3.4 CM (cabinet)
price: $360
Winter 2016-17

Nicely composed specimen presenting a sharp 4.2 CM Aquamarine. No damage, the Aqua has a almost colorless gem clear tip and a deep blue lower section. A small shiny Schorl crystal is protruding from the Beryl. The Erongo area still produces many specimens so the prices of these pieces tend to be relatively lower than from other locales. This one is much better than typical material, in perfect condition, a good value.
