This is a beautiful 4mm Titanium Ring with a brushed center and 18k gold plated edges. It is comfort fit and is a perfect ring for a man or woman. Titanium lives up to its reputation for being strong, while also lightweight and comfortable. Titanium does not tarnish, and although it may show signs of wear over time, it can be polished to look good as new. Unlike traditional rings, titanium is so strong that it maintains its circular shape over longer periods of time.
