For the bold man, a bold ring. Fashioned in durable black tungsten, this 7. 0mm wide wedding band features a single shimmering bezel-set black diamond accent at the center. The inside of the band is rounded for a comfortable fit. This ring is available in size 10 only. Tungsten rings cannot be resized after purchase. Tungsten is a true innovation in jewelry. Tungsten is virtually impossible to scratch and is much heavier and denser than gold. Designed for a modern man on the go, styles in the triton collection are created from high-performance metals that are durable, comfortable and fashionable.
