10K Gold Opal Diamonds Ring Size 7.5

Beautiful vintage 10 karat yellow gold ring with an opal and two little diamonds. Unusually pretty swirling openwork setting, very delicate and unusual. The opal has a very subtle fire and ring is marked "10k". Just gorgeous and overall in good vintage condition, but the bottom of the band is crinkled and out of round. Approximate size is 7 1/2 as is, and the top of the ring measures about 3/8" wide, one gram on my scale.
