Two towering floral tiaras are matched up in this contest!

This naturalistic diamond floral spray tiara originally belonged to Sonia Keppel Cubitt, grandmother of the Duchess of Cornwall. The tiara is now worn often by the Duchess for gala occasions, and in 2006, it was worn by her daughter, Laura, as a bridal tiara.

This intricate, balanced diamond floral tiara originally belonged to a French princess, Anne d’Orleans, who married into the Italian royal family. The piece was inherited by Anne’s daughter, Princess Margherita of Savoy, who passed it along to her eldest son, Prince Lorenz. He became a Prince of Belgium through his marriage to Princess Astrid, who is now the primary wearer of the tiara. You’ll often spot Astrid wearing this one at state banquets and royal weddings.
