Katharina Schmid / The Great Frog

Animal ears: what would school plays, Hallowe'en and Hugh Hefner be without them? These silver ear outline rings are by Austria's Katharina Schmid, whose website is just as playful as her jewellery (hint: the navigation is hidden in the stars).

Bonus link: The Great Frog of London (yes, "frog," not "fog") has an extensive array of skull rings, including this "Michael Mouse" who sports perhaps the most famous animal ears of all.
