Star Garnet Cabochon from India

Description

Star garnets are a unique and captivating variety of the garnet gemstone known for their stunning optical phenomenon called asterism, which produces a star-like pattern on the surface of the gem. These remarkable gems are not only prized for their beauty but also hold geological and historical significance.

Star garnets are a subtype of the garnet family, which is a group of closely related minerals known for their rich colors and gemstone quality. What sets star garnets apart is their distinct appearance – when properly cut and polished, they exhibit a luminous, four or six-rayed star on their surface, resembling a celestial phenomenon. This optical effect is called asterism and is caused by the presence of needle-like inclusions of minerals like rutile or hematite within the garnet crystal.
