Necklaces & Jewelry Of The British Royal Family
It was originally set with 10 of the Cambridge emeralds, acquired by Queen Mary in 1910 and first owned by her grandmother, the Duchess of Cambridge. In 1912, the tiara was altered to take one or both of the Cullinan III and IV diamonds; the pear-shaped diamond was held at the top, and the cushion-shaped stone hung in the oval aperture underneath. Mary lent the tiara to Queen Elizabeth (later the Queen Mother) for the 1947 royal tour of South Africa, and it remained with her until she died in 2002, when it passed to Queen Elizabeth II. In 2005, the Queen lent the tiara to her daughter-in-law, the Duchess of Cornwall.
