A well exposed and sizable (3.7 CM) sharp Franklinite octahedron on Calcite. Old specimen, this Franklinite is quite attractive (for a black mineral) with a good bit of luster on most faces. There are some contacts and bruises as seen on mostly back and sides but still much better than average for this brittle mineral. Good specimens of Franklinite have become very scare and are only available from older collections. This one, despite the rough spots is very fine for the specie.
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.
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.
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
stock #18-AX 19-163
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.
