Japanese jewellery brand Mikimoto has announced a collaboration with Japanese pop culture icon Hello Kitty to launch a new collection of jewellery exclusively at the Fine Jewellery Room in Harrods. The new range, launching 1 September, features signature Hello Kitty designs across pendants, earrings, necklaces and a bangle, as well as a concept designed tiara (pictured above). The tiara is a one-off piece (not for sale), portraying Hello Kitty in diamonds: an oval-cut diamond for the face, claws for the whiskers and a pair of trilliant-cut diamonds for the ears.
