From the triton collection, this 7. 0mm-wide wedding band is crafted in black tungsten and features bevelled edges. The inside of the band's shank is rounded for comfort. Tungsten is a true innovation in jewelry. Tungsten is virtually impossible to scratch and is much heavier and denser than gold. This band is available in select sizes only. Tungsten rings cannot be resized after purchase. 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.
