Dioptase on Calcite
stock #15.1-438
Tsumeb
Otjikoto Region, Namibia
5.5 x 2.6 x 3.8 CM (cabinet)
price: $480
May 2015

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)
stock #14.1-430
Cavradi, Tavetsch, Grissons
Grischun (Grisons), Switzerland
6.5 x 5.9 x 6.8 CM (cabinet)
price: $400
May 2015

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.
Vuagnatite and McGuinnessite (type locality)
stock #ALEC-10-938
Red Mountain, Mendocino County
California, United States
9.8 x 6.2 x 3.1 CM (cabinet)
price: $330
May 2015

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.
Barite w. Fluorite & Pyrite
stock #ALEC-10-846
Niobec Mine, St Honore
Quebec, Canada
8.1 x 2.4 x 1.6 CM (cabinet)
price: $250
May 2015

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.
