We have just received our newest Tungsten wedding bands. Tungsten Carbide is one the hardest metals to scratch on earth. There are just a few manufacturers with the license to make tungsten wedding bands. The patent calls for a very stringent process of very high purity tungsten. We have new bands with black tungsten as well as the new white tungsten. The white tungsten is much whiter in color than your average tungsten band, which is usually gray. They added cobalt to make the band white. We also have a selection now with bezel set diamonds in the tungsten as well as one with a black diamond.
