Calcite

Undamaged grouping of tan colored calcite crystals projecting prominently from a matrix which is covered with a first generation of smaller white calcite crystals. The top crystal is twinned. An unusual locality for me in that it comes from Gralex Quarry, Mont-sur-Marchienne, Charleroi, Hainaut Province, Belgium.

A large tanzanite crystal measuring 6.5cm in length and 3.8 cm in width! The color ranges from a deep translucent blue in the center/bottom of the crystal to a combination blue and white around the balance of the crystal. A clear 1.2 cm quartz crystal sitting on the front edge of the tanzanite crystal provides added aesthetics. This specimen is from Merelani Hills, Lelatema Mts., Simanjro District, Manyara Region, Tanzania.

Two penetrating cubes of Galena, with the largest crystal face being 3.3cm in length, perched on a small bed of matrix. The crystals have great luster. The specimen is from the Sweetwater Mine, Reynolds Co., Missouri.

Two intersecting crystals with good luster. Both crystals are terminated on each end. This specimen is from Mimosos do Sul mine, Mimosos do Sul, ES, Brazil.

This is an unusual thumbnail size specimen. A grouping of copper crystals up to 0.5 cm sitting on a sheet of copper. The specimen is from the Central Mine, Keweenaw County, Michigan.
