Traditionally symbolic of unity and love, the Celtic knot is a striking cultural element that handsomely adorns this 8.0mm tungsten carbide wedding band. Let him know that your love is endless and intertwined. Unique bevelled edges complete the look. Tungsten carbide is a true innovation in jewellery. 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. This ring is only available in size 10. Tungsten rings cannot be resized after purchase.
