The chalcedony I used in this ring have a beautiful luster & seem to glow from within. The top one measures 8mm x 7mm and the bottom teardrop measures 13mm x 9mm. Both are bezel set in shiny 14kt gold fill to my hammered Nu Gold brass adjustable swirl band. I added a patina to the metal to bring out the texture and really make the gems "Pop". Metal has been sealed to protect finish. Front design is just over 1 1/4" long. Size is 7, but is adjustable up or down about 1 size. If you'd like me to adjust the size for you just let me know. Thanks for looking!
