CALCITE ~ ROUGH ROCK ~ 500 GRAMS OR 1 KILO ~ LAPIDARY ~ STONES ~ TUMBLING

Calcite (yellow) rough rock. Because of the relative softness of calcite as compared to other semi precious rocks, care should be taken if tumbling-polishing calcite. The tumbling cycle should be reduced /finer grits used.

• Average piece size: 3cm - 5cm
