This striking calcite and pyrite combination specimen from Chengzhou, China, features a massive, sharply defined calcite crystal formation with luminous clarity. These beautifully formed calcite crystals – including one huge main cubic crystal – are characteristic of this famous Chinese locale and accentuated by a fine dusting of sparkling pyrite that lines the crystal edges for a bold contrast between translucency and metallic brilliance.

Collected over a decade ago and no longer actively produced, this classic Chinese calcite represents both high aesthetic and collectible value. With its interplay of sharp cubic geometry and natural pyrite luster, it makes an exceptional display piece for collectors and museums alike.
