These adorable necklaces are a wonderful way to be one with nature and keep these wonderful gemstones close to your heart. Each of these pendants are tiny glass vials filled with moss and gemstones and attached to an 18″ sterling silver plated chain. The only chain that is not 18″ is the quartz variation, measuring at 23″. You have a choice of gemstones. Glass vials are as shown in the photos.
