This size 6, 7, 8, or 9 sterling silver white fresh water pearl ring marcasite design on the sides is really nice. The top of the ring is about 15mm wide and the faux pearl is about 10mm in diameter. The band at the back is about 3mm thick. It weighs about 5 grams. As with all fresh water pearls, each one is slightly different with possible tiny imperfections. These are very nice though.
