Garnet is a group of silicate minerals that can form in a wide variety of colors, including red, orange, yellow, green, purple, brown, black, and even some rare bright green varieties. The reddish varieties of garnet are among the most common and well-known, but the greener types like tsavorite and demantoid are rarer and highly prized as gemstones. The name "garnet" is derived from the Latin word "granatus," meaning "grain" or "seed," likely referring to the small grain-like crystals and red color of some garnets resembling pomegranate seeds.
