Chemical Composition Of Coral Gemstone: CaCO3

Coral is invertebrate animals or a group of fascinating animals and colorful animals. These animals are called Cnidaria. Cnidaria is exhibited in a variety of colors, sizes, and shapes. An individual red coral animal is known as a polyp.

When each polyp grows copies of itself then that whole process is called budding. The colony is formed by budding process.

Coral gem’s chemical composition is also important for the formation of these sea animals. The basic composition of this gem is calcium carbonate (CaCO3). The specific gravity is 2.65 and the refractive index ranges between 1.486 and 1.658. Its hardness on the Mohs scale is 3.5 to 4. It is a semi-translucent to opaque material.

Wide range of colors: Coral is found in a wide range of colors from warm red to reddish-pink or pale pink to deep red. Coral stones are also found in white pink,  blue and black color. The color variation between these precious gems is because of mixing other minerals during their chemical composition.

Chemical composition of Red Coral Gemstone (Moonga Stone)

Red Coral is made of CALCIUM CARBONATE and its chemical composition is CaCO3 i.e calcium carbonate

Following factors are also important about coral stone

Specific gravity or coral: 2.60 – 2.70

Optical character: Uni axial

Dispersion: None

Fluorescence : Dull

Origins: Italy, Japan, India, Spain, Sardinia, Sicily, Tunisian, France and others countries. The best quality of Coral stone is found in Italy or you can say Italian coral are the best.

Red Coral is a hot gem. It is used to improve Mars. It is responsible for accidents, cuts, wounds, and operations. If one’s Mars is weak or attenuated than that person will be short-tempered, rough in nature and will brute. He will put himself in malpractices. Coral gemstones are known to have many healing powers.
