This tungsten carbide ring features high polish beveled edges with a center of black carbon fiber covering the circumference of the ring. This is a gorgeous ring and the photo doesn't do it justice. This would make an excellent choice for a wedding ring as it is the most wear resistant ring on the planet. It will hold its shape and shine for a lifetime as it is virtually unscratchable. Tungsten carbide is the hardest metal used in the fabrication of men's jewelry. Please note that Tungsten rings cannot be resized.
