This great looking filigree ring is set with .64 carat size Shelby simulated emerald. The ring is made from solid 14kt yellow gold. 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.. they all come with our best in the business guarantee. We can set another type of our gems in this ring at your request. Give us a call at 231 861-2165 or e-mail firstname.lastname@example.org and we'll be glad to help you with your desires.
