Starstone is a rare and precious gemstone that is associated with the heavens and the celestial world. It is also known as Star Sapphire, Nila stone, and Asterism. These synonyms are used interchangeably, with each name referring to the same gemstone. Star Sapphire is named after the Greek word "sappheiros," which means blue. Nila stone comes from the Sanskrit word for blue, while asterism refers to the characteristic star-shaped pattern that appears on the surface of the gemstone. Starstones are valued for their beauty, rarity, and spiritual significance, and have been used in jewelry and religious ceremonies for thousands of years.
