Calcite, Pyrite – Dachang, Guangxi Zhuang, China
 A hand-sized, lustrous, and transparent calcite with pyrite. The fine pyrite crystals have grown only along the edges and on one surface, creating a magnificent graphic aesthetic. The 11 cm crystal is crystallized all around and displays a beautiful recrystallized surface structure on the back.
 An impressive collector's piece of wonderful quality from China. Rare calcite with golden shimmering edges from pyrite, a unique find.
