Bismuth Dimensions: 3" x 4" x 1"
Peru is one of the world's major sources for this native element. Natural crystals of bismuth are extremely rare. This particular piece was grown in a laboratory in Germany. This mineral is actually classified as a semi-precious, semi-metal. Scarce as silver and heavier than lead, one cubic foot of bismuth would weigh over 600 lbs. It is used in both medicine and cosmetics as well as inks, paints and free-machining steels.
