Some rings are about the material. These are about what's done to it.
The Signature Collection is tungsten carbide with the details turned up – grooved channels, two-tone seams in rose gold and black, a polished gold-tone finish that catches the light. Comfort-fit interior. Scratch-resistant. Lifetime warranty.
For the man who notices the stitching on a good jacket and the case-back on a good watch. The ring should keep up.
