For the man you love, this 8. 0mm handsome tungsten wedding band features a fascinating carbon fiber inlay accenting the design. Tungsten carbide is a true innovation in jewelry. Tungsten is virtually impossible to scratch and is much heavier and denser than gold. Metal gram weight varies based on the ring size selected. The inside of the band's shank is rounded for comfort. Tungsten rings cannot be resized after purchase. This ring is only available in size 10. Due to the nature of pre-owned jewellery, the ring you choose may have been previously sized. Ring styles from our pre-owned jewelry 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.
