Color: Yellow Gold - 3.5 mm, Ring Size: 7, Color: Yellow Gold - 3.5 mm, Ring Size: 7
Yellow gold, 14k 35mm in size 7. Beautiful barrel design. Lightweight but solid. Polished & shiny. I am so happy with this ring! It’s just what I wanted. If you’re not sure what millimeter to get, for the 35mm. It’s worth it.
