Gemstone chains are available in various lengths. You can buy it as either a bracelet, anklet, or necklace. All chains come with a 2-inch extender chain added as well. The chain is 18K gold-plated copper. Please note that each stone on the chain is unique and will vary in shape, color, and size. Stone options include tourmaline, aventurine, garnet, herkimer diamond, smoky quartz, citrine, strawberry quartz, and clear quartz. We recommend measuring an existing bracelet/necklace to choose the right length.
