This beautiful ring is made of 925 sterling silver and has three special stones set in it. The first stone is the Herkimer diamond. The second stone is Moldavite, which is a rare green crystal that came from a meteorite and adds a unique, space-like quality to the ring. The third stone is Shungite, a shiny black stone known for making people feel clean and safe. These stones are held in place by simple silver prongs that let you see their rough, natural shapes. This ring is perfect for someone who loves jewelry that is different and full of meaning.
