Our MERCUTIO white carbon fiber tungsten carbide ring is so popular we've made it available in just about every possible width ranging from 4mm up to 12mm. And we don't blame our customers either! The MERCUTIO ring features a dazzling white carbon fiber inlay that looks as lustrous as it is refined when paired with modern age tungsten carbide alloy. Carbon fiber is usually black in color, but our white carbon fiber inlay adds a stylish sophistication appropriate perfectly suited for wedding band wear or just a trendy ring for your jewelry collection. The tungsten metal is polished to a reflective shine and will resist scratching, oxidizing, and fading for the lifetime of the ring. A trendy black carbon fiber version is available as the MACBETH ring.
