Description

Amethyst is a purple variety of Quartz often used as an ornament.  Upon exposure to heat, Amethyst generally becomes yellow, which some refer to as Citrine or “burnt” Amethyst.  It occurs in color from a light, slightly pinkish violet to a deep grape purple.  It is widely distributed as a mineral.

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.
