One of our most popular 2nd generation tungsten rings. This ring is crafted with our 2nd generation black tungsten technology which guarantee the black portion of the ring will always be black, because it is not done by a black plating and it is black all the way through. The center part of the ring features gunmetal tungsten carbide, which a groove in the middle and random horizontal grooves on the two raised ridges. The entire ring is finished in high polish finish and the ring has a comfort fit design. The high contrast of the two materials offered by this wedding band is not offered by any of the traditional gold or platinum rings in additional to the durability of it.
