new june 17
A single Imperial Topaz crystal with traditional color and far above average clarity. In fine condition and mostly gem grade. The color is yellow-orange with a slight hint of red zoning. From the Antonio Pereira area of Ouro Preto, this locality has almost two centuries of history for Topaz finds. This has the most classic and distinctive look for the area but is considerably better than typical quality, form and color.
A very fine plate of Cerussite crystals with minimal matrix from the great Daoping mine, which is world famed for great Pyromorphites. These crystals are in excellent undamaged condition and many are untwinned or are stacked vertically in parallel arrangements with is quite rare. Ex Shield Flynn collection obtained from Bert Ottens, during the period when this area was producing. No more have been available for a few years now Cerussite are up to 2 CM long, translucent yellow and lustrous.
A Cornish Chalcopyrite that is well crystallized and with good luster. Sharp trigons to 1.7 CM across are scattered on a thin plate with stained Quartz crystals between each. Ex Huber collection (Austria), in good condition there is some Quartz or Calcite overgrowths on some Chalcopyrites, and Pyrite is present in the matrix.

A very clear gem Topaz with a slight sherry color perched on a Clevelandite matrix. The Topaz crystal has a number of internal bubbles and negative crystals, it is in excellent condition. Nice esthetics and form, this is all natural color, there has been no irradiation for enhancement. The high clarity lets you see the matrix clearly through the Topaz.
Wulfenite on Calcite
Jianshan mine (stone crack), Ruoqiang County, Bayin gholin prefecture
9.2 x 4.3 x 1.3 CM (cabinet)

A thin plate of matrix hosts dozens of brilliant orange-red Wulfenites with a particularly bright luster. The contrast with the white matrix is excellent and the condition overall is very good, a few chipped crystals at the edges have to be mentioned, but the main central area is quite damage free. From the remarkable finds near Urumqi in Xinjiang. This specimen has not been damaged by cleaning in strong acids so the color and luster are well above average. A good value for such an esthetic piece.

A free-form sculpture of velvety Rosasite from Ojuela. This seems to have formed over a gossan matrix most of which has been etched away leaving this botryoidal mass of Rosasite. Fine color, this is nearly all Rosasite not just a thin coating. From a find in 2012 that was one of the best pockets of Rosasite seen in decades, this is a very attractive piece in great condition.
A fine and very unusual type of of Smithsonite specimen from Tsumeb. Ex John Schneider collection, this has light pink to violet transparent crystals of Smithsonite densely covering 3 parallel fingers or stalactites of Galena. In excellent condition with wonderful esthetics, this is a really weird but choice Tsumeb specimen.
A profusion of Tourmalines with minimal matrix making a complex but esthetic array. The Elbaite crystals are a clear light blue grading to pink and red colors. The main crystals are all perfectly terminated but some of the smaller ones have damaged parts that are not easily noticed. The crystals reach 3.7 CM and are quite three dimensional. An older Pederneira specimen with a form and color palate that is not like more recent material. Choice.
