Teryl Williams of My Passio is on a mission: "To bring bold and unique colors into everyday life one piece of jewelry at a time." If only we could claim to be as ambitious. "Each piece is fired at a minimum of 1450 degrees and placed in the kiln 5 to 7 times to achieve the layers of color combinations over hand cut copper." Some pretty nice work (and some pretty nice photography of jewelry) is at http://www.etsy.com/shop/mypassio.
