Undamaged cluster of yellow Smithsonite crystals on matrix. Crystals reach 2cm in size. A good example of Tsumeb Smithsonite, considered teh world's best, and no longer being found.

Divergent sprays of Azurite crystals on a bit of white matrix. These are the uncommon GEM Azurites from Tsumeb that show great color and transparency when backlit.  Good pointed termination on most crystals.  A few crystals have ragged, unterminated ends but these are natural and not damaged. A rare old treasure.

Highly aesthetic Tsumeb Dioptase, decidedly more colorful than most due to the presence of the baby blue Plancheite spheres. The Dioptase occurs as both small drusy crystals coating Calcite rhombs and larger, highly lustrous crystals to 1.8cm.

Dioptase crystals to 1cm with larger, translucent Calcite crytals to 1.5cm Some damage present but in overall good condition. Typical Tsumeb Dioptase/Calcite specimens have white, rhombic Calcite. This one is a little different with translucent to transparent scalenohedral Calcite crystals.

Bright and transparent Quartz crystal with inclusions of Brookite crystals. This is an excellent example with long Brookite crystals, some of which are fully included in the Quartz and others that partially extend out of the Quartz. The central Brookite extends from the base of the Quartz right up the middle to the very tip of the Quartz! The Quartz is also mostly recrystallized on the base. Great crystal!!

Faceted Spessartine gemstone. A 5mm round weighing 0.75 carats. Good orange color.

Large Carlsbad-twinned Sanidine crystal from France. A species of Feldspar, this crystal out of an old collection and is complete all around and undamaged.

White Carlsbad-twinned Sanidine crystal from France. A species of Feldspar, this crystal out of an old collection and is complete all around and undamaged.

Good coverage of golden Orpiment crystals. The Twin Creeks Mine is a large open pit Gold mine in central Nevada. The Orpiment was found during Gold mining operations in the 1990s. In excellent condition.
