Moissanite is an extraordinary marble which was revealed by Henri Moissan. This was discovered by Henri Moissan, a noble prize winning chemist, so named as Moissanite. Firstly, it was identified as crystals as diamond, but later it was identified as silicon carbide. This stone is formed by the covalent bonding similar to the diamond, so it can withstand even high pressure of 52.7 gigapascals. Diamonds are too expensive to be used in the large ornaments, so Moissanite is used in place of diamonds to give beautiful appearance to the ornaments. It has the same optical properties as diamond.Natural occurring Moissanite is extremely rare and is found only in microscopic crystal. Natural source of silicon carbide is also very rare and only specific atomic arrangement is used for the making of jewelry.
