The Oracle 6mm Carved Celtic Endless Knot Tungsten Wedding Ring features a carved knot pattern circling the ring. Forever Metals Warranties all Tungsten Rings.
The Metal that is used is a Nickel Binder that is higher in quality in comparison to cobalt. Cobalt is a inferior binding agent which may darken the color of the ring over time. Cobalt is most common in lower cost tungsten rings. This is due to the rings being mass produced in countries other than the United States.
Oracle can also be found slightly larger in 8mm Oracle carved endless knotwork celtic rings.
