RM705   Calcite with Fluorite and quartz

Jiepaiyu Mine (Shimen Mine), Shimen As-(Au)deposit, Shimen, Changde, Hunan, China

A perfectly balanced specimen. On the one hand we have a large scalenohedral crystal (5.2 x 2.3 cm.) showing perfectly defined the 180° twin between two scalenohedrons. This crystal is very defined and "doubly terminated" shows good transparency and brilliance. On the other hand we have a group of calcite crystals, also scalenohedral, interpenetrating each other, brilliant and translucent, with a slight yellowish tone. They are disposed on a matrix of tiny quartz crystals on which observe small aggregates of cubic violet fluorite, also interpenetrated. A specimen to be displayed.
