M711 Calcite on Fluorite

M711 Calcite on Fluorite


Here’s a spectacular, very interesting specimen of Calcite on Fluorite from China.  It measures 6 1/4″ x 5″ x 4 1/8″, weighs nearly 5 1/2 pounds and is not polished.  It is loaded with various size and shaped Calcite crystals on a solid bed of green Fluorite. As an added feature both will fluoresce under a LW/UV light creating a whole new dimension.  A mineral like this does not come around that often so grab it quick!

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.

Fluorite, also known as fluor-spar, is a mineral composed of Calcium Fluoride. It is a widely occurring mineral and is often found with metallic minerals such as Galena and Sphalerite, but also with Barite, Quartz and Calcite. It may fluoresce strongly in ultraviolet light. Although green is the most common color, it can also be red, purple, blue, yellow and white.
