Amethyst deep dark richest purple color with rare lustrous calcite crystal from Uruguay
Amethyst is the purple variety of quartz. The name comes from Greek and means protection against intoxication. The largest amethyst deposit in the world is shared between Brazil and Uruguay. It is said to be good for business and to be a healing stone.
 
Calcite is one of the most diverse and collectible minerals. Its natural colour is clear or white but small impurities can create many other shades. Some believe that calcite helps remove negative energy from a space.
