Garnet Dual Stone Ring This gorgeous, unique ring features two 4mm garnets. The open face allows this ring to be slightly adjustable. I handcrafted this ring out of Argentium silver, which is like sterling silver but formulated to be tarnish resistant (It is still marked at .925 Silver), and two small delicate bezels for the stones. Don't see the birthstones or gemstone you want? Send a quick message to seller and I'll get you a quote and availability! These stones make great stacking rings, get them in several colors! Rings are made to order in whole and half sizes 4-16, the band of the ring is 1.6mm thick.
