Turquoise – Cabochon, Blue
In 1810, Napoleon gave his second wife, the Empress Marie Louise, this diadem. Originally, diamonds and emeralds were set in this stunning silver and gold crown. In the 1950s, the emeralds were removed and sold individually. They were later replaced with 79 Persian turquoises. The Marie Louise Diadem, on display at the Smithsonian Institution, photo by Cliff.
