To replenish her collection, she bought a large diamond sapphire Kokoshnik-style tiara from her cousin, Grand Duke Kirill Vladimirovich of Russia.

When she saw the Cartier sapphire sautoir, she felt it was perfect to go with her new tiara, so her husband, King Ferdinand I, purchased the piece in 1921 on an installment plan, paying around 1,375,000 francs in total.

[3] Princess Anne of Bourbon-Parma wore the sautoir without the sapphire pendant at her 1948 wedding to Queen Marie's grandson, King Michael, in Athens.

Queen Frederica notably wore the sapphire on a visit to the United States in 1964 and the wedding of her son the same year.

[citation needed] The sapphire was sold at Christie's as "the property of a noble family" on 18 November 2003 for CHF 1,916,000.
