This is a pretty natural pink quartzite stone ring made in some silver metal. It was labeled as rhodium plated sterling silver, but it definitely is not sterling. It is slightly magnetic, so it is possible it is stainless steel, but there are no markings on the ring. The large 16mm x 12mm cushion-cut stone is genuine quartzite, however, and is a very pretty light pink stone. It is made in a size 9 (maybe just a little over). Its measurements are 0.80 by 0.60 inches on the top of the ring.
