Who doesn't love a mood ring? Choose a unicorn, a shamrock or a more traditional band shape. These have proved very popular in my shop. Seems like everyone enjoys seeing the changing colours. Each ring comes with a sheet suggesting which mood matches with which colour but I should warn you- it's terrible!! No idea who designed it but it probably shouldn't contain romance or despair..... however that really takes none of the fun out of seeing the different colours as the ring changes.
