Calcite on Quartz Calcite on Quartz Calcite on Quartz Calcite on Quartz Calcite on Quartz

Amazingly aesthetic specimen with a translucent 'fan' of pink mangano Calcite on Quartz crystals. There are two light smokey Quartz crystals sticking out in the same direction. The narrow base of the Calcite fan sits right at the tip of the lower Quartz, with the uppder Quartz seemingly propping up the Calcite fan from behind. Undamaged. Just an incredibly beautiful piece, one of those you can't stop looking at.
