Beautiful, unique, outrageous vintage18K multi stone ring. There is no karat stamp, but has been tested as 18K. It weighs 14.8 grams, and is set with the following approximate weights of stones: .30 ctw genuine emeralds, .59 ctw genuine sapphires, and .70 ctw genuine rubies. It is between a size 7 1/2 and 8. It has "bumps" inside the ring which leave a small gap, when measuring it in a mandrel. There is one flaw in the ring. There is a missing emerald, due to a broken prong. I have this area shown on the main picture for this listing. However, I did not have this repaired. Many stones would have to be removed, and the stones reset. The emeralds can break during resetting. So, I think a better option is to "shave" off the one setting, and repolish that area. This would be much less damaging to the ring. If I were to keep this fabulous ring, that's what I would do. Either option leaves you with 2 emeralds. It really isn't that noticeable, unless you are really looking it over. (Which I was). Overall, this is an extraordinary piece, a genuine work of art. Convo me if you have any questions! Thanks for looking.
