Emerald and Diamond Wreath Tiara

 Sources suggest that this piece, which is worn both as a tiara and a necklace by Archduchess Francesca von Habsburg, the wife of Archduke Karl (the current head of the House of Habsburg), was originally owned by the Hanoverian royal family but sold at auction. The piece is composed of diamond wreath elements interspersed with large emeralds.
