Fashioned in black tungsten, this 8. 0mm wide band features a brushed finish accented with polished beveled edges. The inside of the band's shank 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. 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.
