Diamonds are so last century. This ring can carry a plant, and it was made with 3D printing, which pretty much means it was made in the future, for the future. If you wear this ring, you'll be the flashiest girl at the party while showing off your love of nature and technology. This ring is a US size 9 with an Interior diameter of .746" (18.95mm). Since the ring band is wide and it is made of a fibrous nylon material, we recommend sizing up one US ring size.
