Calcite is a very common mineral found in most places on earth. Calcite comes in over 300 different shapes, this is more than any other mineral. Pure calcite is colourless or white, but due to impurities it may also be red, yellow, green, honey, pink, lavender, black, brown or blue. An interesting way of identifying calcite is the acid test.
