VINTAGE Labradorite Sterling Silver Ring, 5

Vintage sterling silver ring with a gorgeous fiery blue-green polished labradorite stone Approximate size 5?— I’m guessing because it is too big for my size 4 ring finger and too small for my size 6 index and middle fingers. Marked 925 Weighty and beautiful, with a high domed cabochon and scalloped edge details around the bezel setting. I’d like to keep this but I never had it sized and thus haven’t worn it. PRICE IS FIRM
