This beautiful ring is set with a heart shaped Shelby Simulated Red Diamond. It is .74 carat size. The ring is made from solid 14kt yellow gold. We can make it in white gold as well. We can cut any of our gems into a heart shape if you'd like a different type of gem in a ring like this. Our simulated colored diamonds are just as hard as our white ones. The red has quite a bit more "fire" than a ruby. Give us a call at 231 861-2165 or e-mail email@example.com and we'll be glad to help you with your desires.
