Solid cluster of nothing but Dioptase crystals, with the focus on a central, large upright crystal. Main crystal is 1.5cm in diameter, rises up 1.5cm higher than the others, and is undamaged.

Flattened, lustrous Azurite crystals on matrix. One edge of the small, uppermost crystal is contacted on edge where it grew against matrix and another small crystal has damage and irregular growth. Nevertheless, the damage does not distract much and it's a very showy piece, and price reflects the damage.

Single large, thick Azurite crystal with a tiny amount of matrix attached to one side. Slight chipping present but overall very clean and complete all around.

Bright, bright silvery Arsenopyrite cluster with aesthetic form. Lustrous and complete all around with some small Apaties on the backside.

Yellow Mimetite crystals on a Duftite covered matrix with a single Cerussite. There are hundreds of Mimetite crystals present in a wide size range from barely visible to 1.5cm long.

A 3cm Brookite crystal on matrix with Quartz crystals.

Cluster of large Paravauxite crystals from the famous Siglo XX (Twentieth Century) Mine in Bolivia. These are very large crystals for the species (the main crystal is 2.1cm!!) - most Paravauxite crystals are under 1cm in size.  The Siglo Veinte mine is the Type locality for this uncommon phosphate species.  Small amounts of blue Vauxite adds color contrast. Big crystals!
