Made completely of tungsten carbide, the 8. 0mm men's ring from the triton collection is durable and lustrous. For a contrasting style, a thick satin-finished stripe stretches across the center. The inside of the band is rounded for comfort. Tungsten carbide is a true innovation in jewellery. 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. Due to the nature of pre-owned jewellery, the ring you choose may have been previously sized. Ring styles from our pre-owned jewellery inventory are sold at their current size and cannot be resized at purchase. As this inventory constantly changes, we are unable to state or guarantee the size of any pre-owned ring.
