This design features a mandarin garnet semi-precious gemstone in a gold plated setting with post; the stone is hand faceted for maximum beauty (FYI- "Semi-precious gemstone" means this is a real gemstone --not acrylic or plastic or resin-- that is found naturally occurring in nature. In the jewelry industry the terms "precious" or "semi-precious" are use to categorize gemstones; precious gemstones mainly include diamonds, emeralds, sapphires, and rubies, and semi-precious gemstones include anything below those 4 that are still within the gemstone classification.)
