Calcite

Colourless, transparent rhombic Calcite crystals stack to form a glassy rib hiding a base of opaque milky Calcite from Tsumeb.  Red staining, due to the presence of iron, taints the base and gives the inner core of the transparent crystals a delicate pink glow.  A beautiful miniature Calcite of lustrous Calcite crystals, many of which display attractive bevelled edges to the rhombohedral form.
