925 Sterling Silver Opal (synthetic) Ring

Slight tarnishing (should come off easily with proper cleaner or toothpaste) I got this years ago and just don’t wear it because it is a little too big for me. Got it originally from this cute little store called Wander when I was on vacation in Osoyoos, B.C. Sizing guess: 6-6.5 in ring sizing Measurements: 18mm inner diameter
