Calcite w. Marcasite
Brushy Creek Mine, Greely, Viburnum Trend District, Reynolds County
8.3 x 7 x 7.8 CM (cabinet)
A castle like structure of sculptural calcite crystals that have sharp phantom of Marcasite. Elegant form and in perfect condition, this is an old Brushy Creek specimen unlike anything seen in decades. Some areas of golden Marcasite are nestled in alcoves between crystals. The calcite spires are undulating in cross section with a vitreous luster and good translucence. A striking and unusual Calcite.
HOLD Dioptase on Quartz

A large slender Dioptase crystal stands a full 3.3 CM tall on a contrasting matrix. The matrix is small gemmy quartz crystals that are clear enough to see the color of the host rock below, likely a Cuprite rich matrix. The Dioptase is brilliant in color, with glass-like luster. One side has a jagged contact that shows some micro crystals overgrowing on it. This has esthetics that stand out and there is no chipping or damage even with 20X magnification.
A sharp, translucent and well formed Ladywash mine Fluorite is nicely decorated with multi-hued Chalcopyrite crystals outside and inside the zoned crystals. In fine condition and with delicate hues this has no matrix at all. The Fluorites when backlit show many Chalcopyrite crystals inside forming distinct phantoms. Choice.
