Swarovski’s Crystal Christmas fairy tale invasion at Harrods is nothing short of dazzling.  An enchanting crystal forest overgrows, housing a selection of Harrods’ most exquisite designer collaborations and one-off pieces from renowned designers such as Ralph & Russo, Erdem and Marios Schwab. Four of the windows are dedicated to a Swarovski pop-up shop where tantalizing jewelry seductively dangles for passersby.
