Frederick Goldman patents new coatings
The manufacturer is applying the coating to its Triton, its line of silver and alternative metal jewelry for men.

New York--Frederick Goldman Inc. has patented three coatings that provide durability, scratch resistance and hardness to the surface of its Triton line of men’s jewelry, the manufacturer said.
Granted by the U.S. Patent and Trademark Office, the patents are for a high-tech coating that utilizes nanotechnology and helps jewelry to sustain vibrant colors through scratch resistance and durability.
The coating will be used on pieces in Triton, Frederick Goldman’s line of men’s jewelry in silver and alternative metals: tungsten carbide TC.850, titanium, stainless steel and cobalt.
Specifically, Frederick Goldman’s multi-layer patents are US 8,932,437 B2 and US 8,927,107 B2. Its single-layer patent is US 8,956,510.
“This high-tech coating with nanotechnology used in the three patents is cutting-edge, and we are looking forward to conducting further studies to expand upon our growing portfolio of patents,” said Andrew Derrig, vice president of technical innovation at Frederick Goldman. “Through leadership in advanced research of new materials and technology, we will continue to manufacture the best quality products for our Triton consumers.”
Frederick Goldman is one of North America’s largest jewelry manufacturers. In addition to Triton, the company also makes ArtCarved, Keepsake, Goldman and Diana and recently acquired Scott Kay Inc.
