Beautifully shiny gold. I’m in love!
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.

Neat and Square
Color: Black, Size: Square
This turned out to be durable and looks good on my valet table. The difference in the way it snaps to the sides, keeps the corners square and looks better than the other models that force the corners to extend outward.
