You've asked for rings in 7mm width and we've delivered with this 7.3mm Dura Tungsten Band with Black Ceramic Tri-Grooved Inlay. The center groove runs the whole ring around and vertical grooves intersect to give a great tungsten and ceramic ring blend. Our lightweight hi-tech ceramic is perfect for wedding bands for many reasons. It is highly scratch resistant, and hypo-allergenic. I've yet to meet someone who can't wear a ceramic band. This ceramic ring comes in black and tungsten in sizes from 7-13 including 1/2 sizes. This ceramic and tungsten wedding ring is 8.3mm in width and has a high polish finish. Comes with comfort fit, made as a special order custom ring in the exact size you need.
