• THE RING – This particular ring boasts a contemporary flat band, slight comfort fit and a matte finish. The matte finish is extremely durable and scratch resistant.

The process allows for an extremely strong, lightweight, comfortable, and truly unique ring. • HANDCRAFTED IN THE UNITED STATES – Each ring is professionally and individually handcrafted on the Space Coast of Florida. • SATISFACTION GUARANTEE – We want you to be completely satisfied with your new ring.
