VINTAGE GOLD & ROUGH CUT DIAMOND RING

I Found this ring at an estate jewelry auction. The ring was tested by the auction house and tested positive for gold and diamonds, however, the ring is not marked. The ring is a size 5 and features eight prong set rough cut diamonds.The diamonds are set flush to the prongs so that they do not snag. I do not know the age of this ring, it appears to be vintage since some of the details of the ring show wear. Please note: I offer a complete refund for any reason with-in three days of receipt of item.
