Garnet is a group of silicate minerals known for their vibrant colors and crystal forms. Commonly found in metamorphic rocks, garnets are often used as gemstones in jewelry. They can be red, green, yellow, or even colorless, depending on their chemical composition. The most well-known type is almandine, which is typically deep red. In addition to their aesthetic appeal, garnets have practical uses. They are often used as abrasives in sandpaper and industrial applications due to their hardness. Some varieties, like pyrope and spessartine, are also sought after for their unique colors and are popular among collectors.
