Kate Moss, Scarlett Johansson and Christian Louboutin have all contributed [1] a charm for this year's limited edition necklace in aid of Cancer Research UK [2]. Each charm reflects the personal experience and character of its creator. Kate's (far right) is a pretty turquoise and silver swallow; Scarlett's (second from left) a white, yellow and orange lily; Christian's (center) is what else but a small golden shoe with his signature red sole.

The necklace, about $51, can be purchased starting September at Wallis [3]. Twenty dollars from each necklace will go towards Cancer Research UK's work.
