japan-based design firm torafu architects has developed 'gold wedding ring'. the jewelry piece gradually transforms as the thin exterior coat of silver plating rubs away to reveal a gold band underneath.
This luminous opal and diamond cluster ring comes from the end of the Edwardian era. The platinum face measures 3/8" and is composed of a square opal cabochon and twelve .05ct single cut diamonds. The shoulders are platinum-topped and the beautiful basket and hoop are 18k yellow gold.
