Gold Cermet is a dynamic material that provides a non corrosive, solid gold ceramic ring that features the hardness of ceramic and the durability of metal. This combination produces a strength that rivals other guides, while remaining lighter and thinner than any other ring material. Add Fuji's diamond polishing and the Gold Cermet ring boasts a finish that's smoother than the SiC ring.
