This is a wonderful ring. It would work well as a cocktail, dinner, every day, anniversary or even an engagement ring. There is a marquise shaped genuine natural tanzanite flanked on each side by 4 round brilliant cut tanzanites going down the sides of the ring. All of the stones are a lovely deep shade of purple and have excellent color and clarity. The setting is a V shaped design. It is really a lovely eye catching piece. This ring is genuine 10 K yellow gold polished to a mirror shine. It has that warm glow and luster that only real gold has. The band is marked 10 K and the piece weighs about 3.2 g.
