Apatite- Ca rich Fluorapatite, classic casts after Anhydite
stock #15.1-339
Geevor Mine, Levant sect. Botallack-Pendeen Area
Cornwall, England
8.3 x 5.2 x 5.2 CM (cabinet)
price: $600
Spring update

A fine old Cornish classic, a cast composed entirely of Apatite crystals have formed casts after Anhydites. The specimen is crystallized on all sides with just a few spots of contact. Lustrous and sparkling and very three dimensional, the shapes of the Anhydrite crystals are sharply preserved. The Apatite crystals are very sharp, glassy, translucent brown color in hexagons with flat pinacoids. Choice, Ex KP hammond collection, these were at one time called Francolite which is now discredited but is a varietal name still in use.
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.
Wurtzite with Quartz
stock #18-AX-15-323 (CO93)
Yaogangxian Mine, Yizhang County
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.
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.
