Garnet is a group of silicate minerals. Commonly recognised garnet colours include red, brown, green, yellow, and orange. The colour depends on the chemical composition, which varies among the different types of garnet, like almandine, pyrope, spessartine, and grossular. Garnets are found in various geological settings, including igneous, metamorphic, and sedimentary rocks. Primary sources are spread across the globe, including the United States, China, Madagascar and India.
