This 8. 0mm-wide etched wedding band is fashioned in tungsten carbide. The inside of the ring's shank is rounded for comfort. 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.
