Acanthite and Polybasite on Quartz
stock #18.1-190
San Juan de Rayas Mine, Municipio de Guanajuato
Guanajuato, Mexico
5.7 x 4.4 x 2.3 CM (cabinet)
price: $440
Spring update

A melted look sculpture of Acanthite crystals on Quartz also holds a few small Polybasite crystals in sharp hexagons. Choice older piece from the San Juan de Reyas mine in Guanajuato. In excellent condition as seen and with a nice dark metallic patina. Under 20 X magnification I can see glints of blood red color that indicates at least a tiny bit of Ruby Silver (Pyrargryite) is also present but very small.

Realgar crystals on Calcite
stock #6.2-833
Shimen (Jiepiayu) Mine, Shimen County, Changde Prefecture
Hunan Province, China
4.6 x 3.9 x 2.7 CM (miniature)
price: $390
Spring update

Brilliant, transparent red Realgar crystals perched on a translucent single Calcite scalenohedron. Older Shimen mine specimen that has been kept in dark storage so the color is fresh and lustrous. Like many Chinese minerals from this era, these were the best examples of their specie and are no longer being mined. A few crystals have slight edge wear but overall this is in pristine condition. Choice.

Grossular with Diopside
stock #18.1-191
VAG Mine, Lowell & Eden
Vermont, United States
6.3 x 4.6 x 3.7 CM (cabinet)
price: $380
Spring update

An old and very unusual Vermont Grossular. From the now classic Mt Belvidere (Eden Mills) locale, these Garnets are a rare light orange hue on pale translucent Diopsides. Most Diopside at this location is a deep green and the Garnets are typically more dark red. Collected over 80 years ago this likely came from a quarry area that simply no longer exists. Ex Warren Johannson collection collected in 1937. At this time the locality was not well known and the major finds were many years in the future. Some chips on a few edges but most of the specimen is intact with many perfect crystals. This habit and style is almost never available except in old collections.

Wurtzite with Quartz
stock #AX-15-323-(C093)
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
8 x 6.7 x 5.8 CM (cabinet)
price: $2600
Spring update

A superb, major specimen of well crystallized Wurtzite perhaps the best example from the great Yaoganxian Mine. By far this is the best and biggest specimen I have seen from this prolific locality, and was on exhibit in the Tucson TGMS special exhibit of Chinese minerals a decade ago. Ex Shields Flynn collection obtained from Bert Ottens who originally discovered Wurtzite at Yaoganxian. Nearly pure Wurtzite, there are hundreds of sharp crystals to 6 MM on all sides with just a few Quartz crystals as contrast. In fine condition and although a "dark ugly" it is oddly attractive. Several have considered this the very best Wurtzite from China, it is obviously important for the locale and the specie.

Elbaite/ Schorl with Fluorite, Quartz etc
stock #18.1-189
Stak Nala, Haramoush Mountains
Skardu District, Baltistan, Pakistan
3.8 x 2.8 1.8 CM (small miniature)
price: $330
Spring update

Dark Tourmalines (deep green- brown to black) that are translucent and very lustrous with a green Fluorite crystal. Small Quartz crystals and Albite are also present. In excellent condition as seen the terminations are sharp and complete. It is likly that this Tourmaline is a mixture of both Elbaite and Schorl in zoned growth. The Fluorite is a modified octahedron and the combination is very attractive. A choice small miniature from the amazing pegmatites of Stak Nala.

Wulfenite -with Descloizite coating
stock #AX-10-167
Ahumada Mine, Los Lamentos
Chihuahua, Mexico
8.3 x 7.8 x 3.9 CM (cabinet)
price: $425
Spring update

A sparkling coating of Descloizite on tabular habit Wulfenites that make up a large part of the matrix here. Very distinctive form and well exposed crystals make this a unique and remarkable specimen. In fine condition overall, this is from the 1960 era, and clearly not like most Los Lamentos pieces. The coating is on all sides except at the small point of attachment at the "bottom", in a few zones some of the orange color of the Wulfenites can be seen.

stock #0636-JM-1597
Kransberg, Usinggen, Taunus Mountains
Hesse, Germany
6.8 x 4.9 x 5 CM (cabinet)
price: $525
Spring update

An old Kransberg German Pyromorphite from the Collection of John Marshall. Johns Pyromorphite suite was an ambitions attempt to gather the best examples possible from every confirmed Pyromorphite location in the world. He obtained many obscure and exotic examples in 60 plus years of effort. This was obtained by him in 1989. The 6.3 x 4.5 CM display surface is covered with mix of Pyro and Quartz with crystals to 5mm., most in good condition. Although no mine was attributed on older labels it looks a good match for the Jennette mine in Kransberg.

HOLD Veszelyite on Hemimorphite
stock #HOLD AX-15-226
Gejiu Ore Field, Gejiou ounty, Honghe Prefecture
Yunnan Province, China
10.2 x 7 x 5.7 CM (cabinet)
price: $720
Spring update

A large blue Hemimorphite in botryoidal form hosts dozens of brilliant blue Veszelyite crystals. Ex Shileds Flynn collection, a very esthetic presentation for this rare mineral. This comes from an important find in Yunnan province that made big news in 2006. The specimen has been sawn on the back/ underside but the display faces are natural in form. The Hemimorphite has a very three dimensional form, and this also has a range of blue hues that add to the relief.
