Style: Retro (more info on styles) Style specifics: Retro Style is a recent designation for the period in the forties when large scale, stylized geometric forms, drapes, bows or ribbons were all the rage. Pink Gold, set with colored stones, sometimes in floral forms was common. Period: ca. 1945 (events and facts in 1945) Material: 18K red gold and platinum, although most of this jewel is in red gold, the diamonds are set in platinum.
