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 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.
Topaz -Classic Imperial type
Antonio Pereira Mine, Ouro Preto
4.1 x 1.5 x 1 CM (miniature)
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.
Deep purple color Flourite cubes in a chain arrangement. From the recent find of stacked or stalactitic Fluorites which had originally formed over Stibnite crystals that no longer present. Some edges have an epitaxial coating of Barite that makes a nice contrast. In fine condition and very esthetic. This was a very small find and few had this intense color.
From the original Karlsbad, this is a perfect Carlsbad twin of Orthoclase. The twin is a complete floater 360 degrees without comtact. There is a second twin perched in the center of the specimen, making this a twin-twin to coin a phrase. This habit got its name from early finds at Karlsbad and this is a textbook perfect example from an old Czech collection.

Yaogangxian Mine, Yizhang County
8.8 x 4 x 3.2 CM (cabinet)
new june 17
A lustrous Bournonite is perched on one end of a doubly-terminated Quartz crystal from Yaogangxian. Remarkably, the entire specimen is fully crystallized and complete on all sides, it is a floater. A modern classic specimen- vintage 2004, the great era of Yaogangxian production. The Bournonite has well defined crystal faces on the front side, however the back side is less distinct, more complex, yet still perfect and undamaged.
