New Metal, BioBlu, Unveiled

A new metal for jewelry, BioBlu 27, was introduced by designer Scott Kay recently.

Kay said the metal is bright, white, and more durable than tungsten carbide. It’s an alloy of 65 percent cobalt, 29 percent chromium, and 6 percent molybdenum and can be cast and milled as well as inlaid with precious metals. The name refers to the biocompatibility of the material, which is used in medical applications such as prosthetics. Blu refers to the cobalt in the material, and 27 is the number for cobalt on the periodic table.

Within the next year, developer Carpenter Technology promises to have a material suitable for stone setting. Kay has created the Brute Cobalt collection for Helzberg Diamonds and his own SK Cobalt line, both of which will be in stores in two weeks, he told JCK. Suggested retail prices start at $125 for one of Kay’s slimmest bands.

The new metal was introduced by Kay; Edward Rosenberg, president of Spectore Corp., Deerfield Beach, Fla.; and Carpenter Technology, Wyomissing, Pa., a maker of metal alloys.
