Tiffany & Co. channels the beauty of aquatic life in its latest Blue Book collection, which pays homage to the late jewellery designer Jean Schlumberger. The Frenchman, who began working with the house of Tiffany back in the 1950s, translated his passion for the underwater world into wildly imaginative pieces. The new high jewellery collection titled Out of the Blue is the first for Nathalie Verdeille, chief artistic officer of jewellery and high jewellery for Tiffany & Co., who dove deep into the archives for this oceanic Blue Book collection. Each necklace, earring, brooch, and bracelet in the 70-piece collection is one of one.
