Red Coral (Moonga)

The Red coral or Moonga, is composed of magnesium calcium carbonate and is a naturally occurring gemstone just like a pearl stone. This amazing gemstone is obtained from deep sea water and grows on underwater plants known as reefs. This red coral gemstone is quite fragile in nature with a hardness or rigidness of around 3.5 on the Mohs scale. Unfortunately, due to the increasing population and global warming, the reefs of red coral are dying which may result in complete depletion of this stone in the future.
