Long, dark green but transparent single Tourmaline crystal from recent production at the famous St. Anne's mine in Zimbabwe. Tourmaline has been very rare from this mine historically, which has primarily targeted blue Topaz. Though dark, it is transparent facet grade throughout with a more greenish brown at the tip and a bright pure green over the rest of the crystal. The crystal has a natural 'bend' near the base caused by natural fracturing and rehealing processes during the crytal's growth. Complete and undamaged and weighs 8.52 grams.

Elongated black Cassiterite crystals to 1.7cm associated with Quartz crystals. This elongated form is uncommon for Cassiterite and these are perfect undamaged crystals. Ex. Erich Laskowski collection.

Blocky, gemmy crystal of Montebrasite with attached Albite. A beautiful well formed crystal of this rare species that has good color and is complete all around. There is a bit a roughness on the left edge where some Albite grew, otherwise it has smooth flat faces all around. A really nice gem crystal. Ex. Erich Laskowski collection.

Doubly terminated single crystal of Lorenzenite in matrix. The crystal is 2.3cm and undamaged. Lorenzenite is a rare sodium titanium silicate mineral. Ex. Erich Laskowski collection from the Fersman Mineralogical Museum.

Shallow Calcite lined vug loaded with bright Diioptase crystals. Ex. Erich Laskowski collection.
