Unlike most other gemstones which are of mineral origin, corals are organic and formed by living organisms. They are formed from branching, antler-like structures created from coral polyps in tropical and subtropical ocean waters. Most of the corals found in the ocean are generally white, but nature can create coral in several other colors, including the popular orange to red forms. Red coral, or precious coral, is the most used gemstone form of coral. Both white and red coral gemstones are widely used for their astonishing healing properties and numerous astrological benefits. Let's dive deeper to understand each gemstone and find out which one is the most beneficial for you.
