The twinned habit of the Calcite crystals on this specimen is known as "Poker Chip" because of the disc shapes reminiscent of poker chips. The color of this specimen is an off white with the top surfaces whiter than the sides. On some of the larger crystals, layers can be seen. The largest crystal is 3 cm across at its widest point. The specimen is in very good condition with just some very minor bruising on a couple of the corners.
