Vintage Ring 18k Gold Emerald Diamond Estate JewelryA massive oval faceted emerald round brilliant cut diamond ring made of 18k yellow gold. It's an impressive Mid century piece that carries a lot of character. Two rows of diamonds surrounding the emerald are set one above another. The four prong setting of each diamond is circled with the braided gold frames. That creates a fluffy, almost foamy effect and makes the emerald look even bigger.
