The 16 gauge 3/8" cz butterfly hinged segment ring is made from high polish grade 23 titanium (Ti 6Al-4V ELI ASTM F136). These look just like a regular segment ring, but so much easier to use (no ring openers are required). These cannot be returned or exchanged if you select a custom anodized color. Only the high polish (plain silver) is eligible for our return policy. Choose the color of your marquise cut gem below.
