Pliny the Elder named Calcite nearly 2,000 years ago. Calcite is from the Greek word "chalix", which means lime. Calcite gemstone beads come in a wide range of colors. This stone is rather soft, and should not be used for jewelry that will see rough wear.
Calcite is a calcium carbonate and found abundantly all over the world. Calcites are often found in limestone.
Calcite is said to be an amplifier for cleansing energies in metaphysical beliefs.
