This pretty pendant is set with a 1.52 carat size heart shaped Shelby simulated red diamond. This pendant is made from solid 14kt yellow gold. This pendant is priced without a chain. You can add a matching 10kt or 14kt solid gold chain from the options down below. 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 firstname.lastname@example.org and we'll be glad to help you with your desires.
