Calcite Crystal

A substantial formation with a thick lining of large white quartz crystals that contrast beautifully with the two honey coloured calcites to the side.

This striking and unique crystal formation features a hefty double terminated Calcite crystal with another double terminated Calcite growing through the bottom at a 90 degree angle.

The red color of the calcite crystals is caused by microscopic hematite inclusions.

The pink color of the calcite crystals is caused by the cobalt impurities.
