Birthstone: Garnet is the birthstone for the month of January. It is often given as a gift for birthdays and other special occasions. Geological Formation: Garnets are found in various geological settings, including metamorphic rocks, igneous rocks, and alluvial deposits. They are often associated with minerals like mica and schist. Jewelry Use: Garnets have been used in jewelry for centuries and are popular in rings, necklaces, earrings, and bracelets. They are often used as both faceted gemstones and cabochons. Color-Change Garnets: Some garnet varieties exhibit a unique property called color change, where the gemstone appears to change color under different lighting conditions.
