Calcite
_____________________________________________________________________________________

Calcite is the crystallized form of calcium carbonate.

Calcite is found in several colors with colorless calcite being the most abundant form. Honey colored and orange calcite are relatively abundant forms. Green and red calcite are the rarest.

Hardness of calcite on Mohs scale is 3 that makes it prone to scratches very easily.

Calcite takes excellent polish and its luster is very vitreous and attractive. The luster of calcite is so glassy that it might exhibit a wet look.

Gem grade colored calcite of excellent color and clarity is a rare finding.

Calcite is rarely used in jewelry because of very low degree of hardness.
