One of the most exciting new finds this year are these very colorful Pseudomorphs from the Congo. This specimen is especially well formed with big (up to 6.2 CM) sharp crystals showing Azurite form. The crystals are now hollow casts with a small amount of residual Malachite seen inside with magnification. The entire specimen is covered with tiny, sharply terminated crystals of deep blue Chrysocolla. In fine condition esthetic and eyecatching.
A complete 2.9 CM crystal of Rhodonite is perched above a smaller 2.3 CM crystal resting on Calcite matrix. Nicely exposed, the Calcite has not been acid "melted" so this is fully natural. An affordable classic specimen with good color, form and in nice condition, these are getting quite
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.
Dioptase on Quartz
Democratic Republic of Congo (Zaire)
3.8 x 2 x 1 CM (miniature)
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.
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.
An exceptional orange-red Sphalerite from a one time find made over 40 years ago. Ex John Marshall collection, in fine condition and according to John's notes this was the best piece offered in Tucson at that time. The individual crystals reach 1.5 CM, are quite translucent and stand out from the matrix very well. Complex twinning and overgrowths in the individual crystals adds some color zoning as well. Impressive as is (this has never been professionally prepped) and impossible to find on the market in any quality.
Titanite v. Sphene
5.6 x 5.5 x 5.1 CM (cabinet)
A sharp and "monumental" looking cluster of Titanite in crystals to 3.1 CM. Transparent and with a good green color, some faces are smooth and glass clear and others have micro steps and a more etched look. Unknown inclusions add a little red zoning in a few spots. In very good condition for the specie, esthetic.
Jeremejevite gem crystal
Erongo mountain, Usakos and Omaruru districts
2.6 x .5 x .4 CM (small miniature/ large thumbnail (toenail))
A fine gem clear Jeremejevite that is much larger than average and with clean, sharp form. Ex Bill Pinch collection, distinct color zoning ranges from deep sky blue to clear. Sharp termination and glassy sides make this a very pretty example of this rare mineral. Found prior to 2002, this quality is now very hard to find.
