Queen mother's Ginkgo coronet by Boucheron
Boucheron created this diamond Ginkgo coronet in 1901 for Mrs. Greville who was a close friend of both Queen Mary and Queen Elizabeth the Queen Mother.
In 1921 stones from this coronet were used in a tiara now known as the Boucheron Honeycomb Tiara, also known as the Greville Tiara. The Queen Mother left the tiara to the Queen who now loans it to the Duchess of Cornwall who wears it on state occasions.
