The Delhi Durbar necklace and the Vladimir tiara with Cambridge emeralds
The Vladimir tiara was smuggled out of Russia after the revolution and bought by Queen Mary. She was also in possession of the Cambridge emeralds which had been won by her grandmother, and so she had several of the stones set so they could hang in the Vladimir. The necklace was created for Mary for the Delhi Durbar — the ceremony to commemorate the start of her husband George V's reign in India.
