Sparkly and absolutely stunning, I bought this ring for myself but the seller had the size wrong and I couldn’t return it. It’s a (presumably) synthetic opal with gorgeous pinks and greens that put on a show in the light. It’s nestled in a wavy little 14k gold setting on a textured sterling silver cigar band. Very organic shapes! Roughly size 8.5–see photo and use your best judgement, considering the width of this band.
