Is It Calcite or Dolomite? | Rock & Gem Magazine

Calcite, a calcium carbonate, is the most common of the carbonates. We admire its lovely crystal forms—all 600 of them. We also use it in huge quantities in its massive form, limestone. Dolomite, a calcium, magnesium carbonate, is not as common as calcite. It also forms in lovely crystals, but not in as wide a variety as calcite.
