The sophistication of the brushed satin finish may first attract you to this white tungsten wedding band, but it's the materials that may sway your final buying decision. While most tungsten carbide rings use cobalt as a binder, this ring uses a nickel binder. Nickel is superior to cobalt because it doesn't irritate the skin or oxidize over time. Since tungsten is one of the strongest metals available in the jewelry industry today, you're left with a hypoallergenic wedding band that will stand the test of time. Add the stunning shine of high polished edges, side bevels and a rounded interior for comfort, and you see why this is an engravable 8mm wedding ring for men or women.
