Cast Fingerprint Ring. Available is sterling silver, oxidized silver, gold fill, 14K yellow and 14K white gold. You can add a diamond on the 14K options. I love this ring! I wasn’t going to make one but a friend encouraged me to and I am glad I did. It is sculptural and comfortable to wear. The ring has a great tactile quality to it. It is an everyday ring or a cool cocktail ring all depending on the metal you choose.
