Today we know the Halo Tiara as the wedding tiara of the Duchess of Cambridge. But originally it was made for Queen Elizabeth (the Queen Mother) by Cartier in 1936.
The diamond tiara is in the shape of a “halo” and has 16 scrolls. It’s set with 739 brilliant cut diamonds and 149 baton (cut in a long, thin rectangular shape) diamonds. Each scroll is divided by one brilliant cut diamond. The largest diamond is reserved for the center of the tiara.
