Its not new, I bought it in the late 1990's early 2000 from a reputable jewelry store & wore it mostly for special occasions. I've never had it appraised so I have no idea the size or weight of the stones or if the amethyst is genuine or lab-created but the diamonds do test positive with a gemstone tester & its stamped 14K. Its a size 5.75 and, although I think it can be sized, I can't say for sure as it may differ from jeweler to jeweler. Its a gorgeous ring & much prettier in person! Reasonable offers considered!
