Vintage amethyst and clear crystal 10K Yellow Gold Filled. There's some wear on the bottom of the band. Please see the pictures. Many of the jewelry items listed are antique, vintage, and/or pre-owned. Items have had a life before found. Items may show evidence of that previous life; signs of wear, dents, scratches, oxidation, broken stones, etc. I strive to be accurate and transparent in the descriptions of these pieces. I'm not a gemologists. I choose pieces based on their overall aesthetic and how well they accessorize. I try my best to accurately describe the stones in my jewelry items but cannot absolutely guarantee them. I want the true age of the piece to be represented, so I do not perform any type of cleaning or polishing. If the item is oxidized when I acquire it, that is precisely how you will receive it.
