This sterling silver ring mounting features an open shank design with two basket mountings—one on each end of the shank. Each mounting holds one 10 x 8mm (approx.) faceted stone; one oval and one octagon. Mix or match stone types to create the perfect gemstone combination for that special customer. Basket settings feature open sides designed to allow more light to reach and move through the stone, enhancing its brightness and brilliance. Cut a seat in the prongs to accommodate your stone, then burnish the prongs over the stone to secure it in place.
