Very Nice Mid Century Modern 18 K White Gold 5 Diamond Sz 5 Swoosh Dinner Ring This is a wonderful and unusual ring. It would work well as a cocktail, dinner, every day, anniversary or even an engagement ring. There are 5 genuine natural round brilliant cut diamonds. They are mounted inside of a sort of swoosh design. All of the stones have excellent color and clarity. It has a retro feel but still works very well as a modern ring. This ring is genuine 18 k white gold polished to a high mirror shine except for the textured areas. It has that warm glow and luster that only real gold has. The inside of the band is marked 18 K and the piece weighs about 3.9 g.
