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.

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.
