Wedding present from Napoleon to his second wife, empress Marie-Louise. The empress left the parure to archduchess Elisabeth. It was sold in 1953 by her descendants to Van Cleef and Arpels who removed dramatically the emeralds from the tiara to create new jewels and replaced them by turquoises. The tiara was bought later by Marjorie Merryweather Post for the Smithsonian Institution of Washington where it's now on display. The necklace and earrings have been acquired by the Louvre, no idea of the whereabouts of the belt buckle
