This is a wonderful ring. It would work well as a cocktail, dinner, every day, anniversary or even an engagement ring. There is a large 17 X 12 mm very clean black onyx oval stone. The setting is wide and has oriental designs on the side, they may even be words but I do not know. It is really a lovely ring. This ring is genuine 14 K yellow gold polished to a high mirror shine. It has that warm glow and luster that only real gold has. The band is marked 14 K and the piece weighs about 4.5 g.
