M302 South Dakota Calcite

M302 South Dakota Calcite


Here is something different for the mineral collector, an amazing piece of Calcite from South Dakota. It measures 4 3/4″ x 2 3/4″ x 7/8″ thick. It has a unique shape (looks like a Dolphin) and lots of character. It will even fluoresce under a UV light and has a “rainbow” under the UV light. Very cool!

Calcite is a Carbonate mineral that is most widely distributed on the Earth’s surface.  It is a common constituent of sedimentary rocks with Limestone in particular.  A Calcite formation can take on many different shapes and sizes which is dependent on the location, ground water occurrence and temperature.  Calcite is usually white or colorless but can be gray, red, yellow, green, blue, violet, brown or black.  The deeper the color is usually indicative of the definitive impurities from the earth or water.
