Green CZ Cocktail Ring Our customers requested a Simulated Emerald cocktail ring, and here at Emitations we love to please! This Ring holds a magnificent 5 carat Emerald Cut center stone, flanked on either side by a clear, round cut Simulated diamond. The side stones are a quarter carat each, which gives the ring a TCW of 5.5. The prong settings are accented with swirls of sterling silver, which add the finishing details to this regal ring.
