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.
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.
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.
Malone Quarries, Hastings Co.
3.5 x 2.9 x 3.3 CM (miniature)
Sharp. clean prismatic Epidote crystals from a less known locality. Crystals are well terminated and reach 2.5 CM in length. The only noticable damage is on the outside edges where this was removed, otherwise this is in quite good condition.
Jeremejevite gem crystal
Erongo Mountain, Karibib
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.
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.
Copper and Gold on Quartz
3.6 x 2.3 x 2.1 CM (miniature)
An exceptionally rare combination of well crystallized Gold on well crystallized Copper. This is a nice Copper specimen with elongated spinel twin crystals in esthetic curving "horns" and some distinct texahexahedral crystals. What makes it special is the addition of several areas of well crystallized native Gold. The gold is best seen with a loupe but some is eye visible with well developed branching sprays and bright yellow metallic color tucked in several areas on the specimen. This little known mine is one of the few locales that ever produced Gold on Copper, and by far the most attractive. There were not many pieces in the find, these are are now almost impossible to find. This one is the best I have seen.
A sparkling bright purple matrix is the host for lustrous white Scheelites to 1.5 CM in size. An unusual combination (to me at least) from Yaoganxian, this is in fine condition. A few Dolomite crystals are sprinkled on the Scheelites and on the back of the matrix. Several options for display angle, the color is a little more vivid in person.
