Wonderful Vintage 10K yellow gold double fiery opal ring. Ring is a size 6 (easily re-sized) and weighs 2.9 grams. The ring has two prong set approximately 5mm fiery opals that sit 7mm above the finger. Hallmarked on the inside of the band "10K", the ring is in excellent Vintage condition. There is a tiny chip on the outside, almost underside of one stone. The only way I found it was by running my finger around the stone. Not really noticeable to the naked eye.
