Opal & Amethyst Sterling silver & Gold Marked STS statement runway ring

FINAL PRICE WAS $489 Absolutely stunning and unique!! Marked STS and 925 opal cluster sterling silver statement runway ring. With so much detail... like 3 rows of 3 prong set lavender amethyst stones up each side of the band and gold wash filigree work between. On the top sits 10 opals. I don't for sure know if they are man made. But I feel like most are man made in the last 10 years. Between each is another tiny amethyst. This is a size 9 and over 1 &1/2 inches long Excellent previous owned condition
