This is a beautiful white and yellow gold London Blue natural topaz ring. It's made out of 14k solid gold. It's a ring size 7.5. It weighs a total of 4 grams. The ring features a breathtaking filigree design. The topaz measures a bit over 1/4" tall and a bit over 3/8" across. The ring is very flattering when worn. Let me know if you have any questions, I'm more than happy to answer them. Thanks for stopping by!
