This ring is made from solid 14kt white gold. We can make it in solid 14kt yellow gold too. It is set with a beautiful Shelby simulated emerald. Our simulated emeralds are in most ways better than natural emeralds. Ours are much much harder and more sparkly. Not to mention, they don't have the cracks and inclusions often found in natural emeralds. AND... ,like all of our gems,.. they come with our best in the business guarantee.
