This unique diamond band for him features a durable tungsten and ceramic setting and three black diamonds totalling 0.09 ct. Tungsten is a true innovation in jewellery. It 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.
