Set of 6 transparent orange Villiaumite crystal from the open pit phonolite quarries in Aris, Namibia. These quarries, along with the Kola peninsula in Russia, are the source of the world's best Villiaumite. Although larger, the Kola specimens are a darker purple red and are typically just cleavages rather than crystals. These bright orange, transparent crystals are far more aesthetic for my taste. These crystals have etched outer surfaces and are internally transparent (faceted gemstones are known from this occurrence). The crystals in this set reach 1.2cm wide.

Single octahedral Spinel crystal from Tanzania. A complete, translucent red crystal with minor edge chipping.

Single twinned Spinel crystal from Tanzania. A complete spinel-twinned crystal, translucent purple with minor edge chipping.

Seven crystals of Chambersite. All are complete tetrahedrons, some with modified terminations, and two that are clusters of crystals. Largest is 4mm on edge. The crystals are translucent purple in color. A rarity that are also quite beautiful with an amethyst-like color. Collected by Fred Pough in 1970. Ex. Chuck Trantham collection.

Sprays of blue Caledonite crystals with Leadhillite crystals to 3mm. Ex. Tim Sherburn collection.

Glassy, transparent single smokey Quartz crystal from the Pack Rat Mine. A complete crystal with some Albite grown into the backside and some like colored inclusions that appear to be mica.  Ex. Cal Graeber Quartz collection number Q-347.

Copper crystals on green Prehnite lining a vug in basalt. The largest Copper crystal is 1.1cm tall. This is possibly from Osceola Mine, but comes with an old label stating the Michigan Mine.

Spherical cluster of yellow Brucite on matrix from Pakistan. The Brucite is highly translucent to transparent, about as translucent as it gets.  There is alot of Brucite available now, but not of this quality. 

Transparent, deep green cubic Fluorite crystals from the Rogerley Mine. Daylight reactive with blue highlights. From an old stash of crystals highgraded from Cal Graeber.
