I believe this ring was purchased anytime from 1950-1970 it was bought for my grandmother by my grandfather so I know its old He was in the Navy so this ring could be from anywhere The opal is genuine and the gold is 10k yellow It has been professionally cleaned and the prongs/tips rebuilt. it was just sized down to a 4 for me to wear but I changed my mind about keeping this ring 😔 Right now the ring is a size 4 but I'm willing to have it professionally sized again for an additional cost (I will have to know what size you need before updating the price) it really is a gorgeous ring but unfortunately I just can't bring myself to keep it, y'know how family is let me know if you have any questions offers and bundles encouraged :) I have lots of other jewelry for sale as well! *tagging catbird for exposure*
