Dioptase on Calcite
5.5 x 2.6 x 3.8 CM (cabinet)
The classic Tsumeb combination of emerald green Dioptase with snow white Calcite in an esthetic composition. The Dioptase is bright and glassy reaching 1.7 CM in size. There is some contact/damage on the backside but the display face is in fine condition. No other Dioptase from anywhere has the same look as these old Tsumeb specimens.
Smoky Quartz (Alpine)
Cavradi, Tavetsch, Grissons
6.5 x 5.9 x 6.8 CM (cabinet)
Good Alpine Swiss Quartz has a look that is unlike any other. This has a main crystal 6 CM in size that has a warm brownish hue and is gem clear. The main crystal faces are glasslike and lustrous in close to perfect condition- only a very tiny nick as seen in the photos. The matrix is all quartz and has a few partial and complete crystals that offset the main prism nicely.
Celestite on Sulphur
Machow Mine, Tarnobrzeg
9.3 x 6.6 x 4.9 CM (cabinet)
Post Tucson 2015
Bright and gemmy Celestite (Celestine) crystals are in radial sprays on vivid Sulphur crystals. In fine condition, the matrix is an open pocket that has protected the delicate crystals inside. Similar to old specimens from Sicily, the luster and sparkle of this specimen is equal to those.
Pyromorphite elongated xls

Perfect 360 degree "floater" compound crystal of fine green Pyromorphite from the famed and prolific Daoping Mine. Outstanding hoppered form with distinct striations on all faces. No eye visible damage, micro chips under .1 mm can be found with 20X magnification. This is far better than most of these large crystals and it displays well.
From a little known Chinese locality, These Corundum crystals are well formed and similar but noticeably distinct from the better known Madagascar specimens. Individual crystals reach 1.6 CM and are a blueish hue in daylight but have a more purple-red look in some artificial lights. The color change is subtle but clear. In very good condition, the crystals are well exposed and have a small amount of translucency at the edges.
A sizable matrix densely covered with white to colorless Vuagnatite crystals and contrasting McGuinnessite in green spheres. Vuagnatite is a rare mineral discovered in 1975, and McGuinnessite is very rare, discovered in 1981. This is from the type locale for Mcguinnessite, and is a very good specimen of both species. This could easily yield several fine thumbnails if trimmed out. Very good color and bright sparkling luster make this an unusually attractive rarity.
A single chisel tip Barite crystal partly jacketed in Fluorite (uncommon on these), Calcite and Pyrite crystals. Translucent, with some color zoning and a rosy core, this is a sharp example from this famed find. The Fluorites are not often seen on the Niobec Barites, these are gemmy and colorless but the pyrite adds a yellow hue to some. Nearly all of these have broken terminations as they grew on the roof of the pocket and fell off long ago. This one is nearly perfect, a slight cleave is noted on the tip as the only issue.

Twinned "drill bit" habit Cinnabar crystals on Quartz matrix with some Dolomite. A Chinese classic, for over a century Cinnabar was the only Chinese mineral seen in the western world. These were prized specimens in top collections and were the worlds best examples of the specie. Things have changed and these are no longer priceless but they are still quite fine and this habit is the most desired. Crystals to 1.8 CM most of which are fully perfect however a small one has a backside cleave not seen on display. The dark color and habit are typical of older material that is not like any of the recent finds.
