Our moissanite tension engagement rings are made with a secret precious metal alloy mixture that causes the metal to pull towards itself under extreme heat. This tension secures the moissanite center stone in place with 12,000 PSI of pressure. Your tension engagement ring will hold your choice of Charles and Colvard Moissanite or NEO Moissanite center stone more securely than a typical 6 prong head. Looking for a matching wedding band? All of our moissanite tension engagement rings can be paired with an exquisite custom fit wedding band for the perfect match!
