A unique specimen of white hexagonal columnar calcite with black scalenohedron colour zoning from Fujian, China. It is a two generation growth calcite where the inner black scalenohedron formed first, then the white hexagonal calcite covered the black crystal.
The reverse matrix side appears to have druzy quartz covering. Specimen of this kind was first discovered in Nov 2017, it is a unique crystal habit for calcite only found in China, quite uncommon and the locals called it "panda calcite".
