A 8mm wide, highly polished band with the most durable black plating will make this ring last a life time. What an Exquisite and timeless piece of art! It features comfort fit design. Tungsten is one of the hardest metals on the planet. It's durability is absolutely unmatched in the jewelry industry. Tungsten is 10 times harder than 18K gold, 5 times harder than tool steel and 4 times harder than titanium. It measures between an 8 and 9 on the Mohs scale, with diamonds being the highest at a 10. Tungsten has been used for decades in industrial applications where only the strongest and hardest metal will suffice. The incredible strength and timeless beauty of our tungsten rings will have you cherishing them for a lifetime. All of our rings are manufactured with tungsten carbide using nickel as a binding agent. Many companies choose to use cobalt as a binder because it is slightly cheaper. While either element will work just fine, cobalt has a higher tendency to have adverse reactions with some people's skin. This is why we use nickel. Although in some extremely rare cases a customer will discover he or she has an allergy to nickel, our rings are generally considered to be hypo-allergenic.
