The MACBETH ring is a customer favorite black carbon fiber tungsten wedding band available in a wide range of widths from 4mm to 12mm to accomodate any finger size and desire. The stately black carbon fiber pairs exquisitely with the polished beveled edges, giving the band a smart look. Carbon fiber is an expensive, light weight, ultra-strong modern day material--a perfect complement to the high-tech tungsten carbide material. Tungsten rings are harder than other type of ring, look sharp, and affordable. The MACBETH ring is shaped in a comfort fit band. A unique white carbon fiber version is available as the MERCUTIO ring.
