Scott Kay Gentlemans' cobalt wedding ring, measuring 7 mm wide

Like New With the price of gold, platinum and even palladium and silver breaking records daily, jewelry designers and manufacturers have been looking for low-cost alternative metals. For jewelry designer Scott Kay, an answer for men's wedding bands is Cobalt. More specifically the answer is BioBlu 27, a metal alloy made of 65 percent cobalt, 29 percent chromium, and 6 percent molybdenum. According to Dan Scott, Scott Kay chief marketing officer, this non-magnetic, naturally white metal alloy has high strength, corrosion resistance, and wear resistance. "This metal is as white as platinum. It doesn't tarnish, chip or fracture," Scott said. "And it isn't plated. It's white, through and through."
