Kransberg, Usinggen, Taunus Mountains
6.8 x 4.9 x 5 CM (cabinet)
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.
Barite on Stibnite
Dahegou Mine, Lushi County, Sanmenxia Prefecture
10.9 x 1.4 x 1.4 CM (cabinet)
Unusual and neat association. A Stibnite crystal with some bends and a hackly termination has two white transparent Barite crystals on the middle section. The Barites have some milky faces and others that are very clear so the underlying Stibnite can be seen through the crystals. From finds in 2005 we have not seen more of this type since that era.
Veszelyite on Hemimorphite
Gejiu Ore Field, Gejiou ounty, Honghe Prefecture
10.2 x 7 x 5.7 CM (cabinet)
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.
Copper with Quartz
Onganja Mine, Windhoek District
5.1 x 2.8 x 1.7 CM (miniature)
A crystallized sculpture of Copper from the famed Onganja mine that has several crystallized Quartz clusters perched. In fine condition, the Quartz seems to have formed on a Calcite core. A rare association, the tiny Quartz crystals are very clear, adding a sparkling accent. The Copper is in branching crystals with some showing crude spinel twinning and flattened, stretched octahedrons. Quartz is not a common association in these coppers.
Barite with Calcite
Meikle Mine, Bootstrap district, Carlin Trend, Elko County
4.7 x 4.4 x 2.3 CM (miniature)
A large, clear golden Barite crystal sits on a few smaller Barites and minor Calcite. The main crystal is well presented, doubly terminated, tabular habit, lustrous and pristine. There are crystal contacts in a few areas but no damage. A modern American classic locale, the Meikle mine has produced many great Barites at one time. This specimen was collected well over a decade ago in the hight of production. better in person too.
The rare deep indigo blue Plumbogummite from the earliest finds at Daoping that is very different from the later powder-blue replacement crystals. This botryoidal mass covers a bright yellow to greenish zone of unaltered Pyromorphite. Sawn on the base and with some bruises mostly at the outer edges, so this is not for a perfectionist but is still choice and very attractive for one of these. For centuries the worlds best Plumbogummites were the British specimens that were priceless treasures in top collections. This Chinese specimen even though modest is richer and esthetically superior to most of those. Collected before 2004 from a zone that was mined away soon after.
Fluorite on Muscovite and Quartz
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
4.2 x 4.1 x 3.2 CM (miniature)
Glassy transparent and sharp cubes with areas of deep purple color zoning. The matrix is visible through the Fluorites. No damage. This sort of Fluorite once came out in large amounts from Yaoganxian, though undamaged pieces were much less common. A modern classic location, the supply of nice pieces is drying up but some are still relatively affordable.
A single terminated Elbaite crystal 3.1 CM long is nicely set on Clevelandite blades from the famed Stak Nala pegmatites. A few crystals of the Clevelandite have grown into the Tourmaline but most of it is well exposed and fully visible. In good condition, the three color Elbaites are much less common at Stak Nala. A cute miniature that is quite affordable for one of these.
