World renowned for his eighteen karat blue gold, purple gold, gold mokume gane, and other magical precious metals, he captured mysterious yet fundamental forces of nature and transformed them into timeless works of art. Steven’s signature Tension-Set™ jewelry and magnetic Polarium™ platinum jewelry have revolutionized fine jewelry design.

During his career, Steven had received numerous awards for his continual success in extending the boundaries of fine jewelry design. He had also been granted a number of patents for precious metal product inventions and alloys, including multicolored layered golds, tension settings, and Polarium™, a permanently magnetic platinum alloy developed for a line of fine jewelry that exhibits amazing behaviors, including levitation.

Steven Kretchmer’s continual development and use of unique precious metals, displayed in ageless designs with diamonds and gems, added new dimensions to the fine art of jewelry.
