If you're looking for men's wedding bands and you're in the market for tungsten rings, you know that tungsten wedding bands are the new industry standard for quality. Tungsten wedding rings have been referred to as the "Permanently Polished Ring," but not all tungsten bands are created equal. Our tungsten carbide wedding bands are not cheap wedding bands in quality. EVERY SINGLE ONE of the tungsten rings at Wedding Rings Forever upholds quality standards most companies choose to ignore in their wedding bands. Our mens wedding bands are cobalt free. This is VERY important! Most people are fooled by cheap rings which contain cobalt and take away the qualities of true tungsten carbide. The cobalt must be substituted by nickel to retain its hardness and hypo non-allergenic traits. One might ask, why don't you use pure tungsten? Tungsten carbide has been proven to be harder and more scratch proof than just the metal alone! Our tungsten bands are 10 times harder than 18K Gold, 5 times harder than tool steel, and 4 times harder than titanium. Tungsten measures between 8 and 9 on the Mohs hardness scale. (Diamonds are a 10 - the highest.) Our tungsten rings will not bend, scratch, or warp in any way. They are the toughest rings on the planet and will truly last FOREVER. In a medical emergency, our tungsten carbide rings can be easily removed by a medical professional or experienced jeweler. We test each of our hand-made and hand-polished high quality rings.
