As the piece’s name suggests, this brooch was given by Emperor Francis Joseph of Austria to Queen Mary’s mother, the Duchess of Teck, in 1870. The diamond and pearl brooch was a gift to mark the christening of Prince Francis of Teck, for whom the emperor served as a godfather. Prince Francis inherited the brooch from his mother, and when he died suddenly in 1910, the brooch (and the Cambridge emeralds) were famously inherited by his mistress, Lady Kilmorey. Hugh Roberts tactfully notes that the brooch was “retrieved” by Mary from Lady Kilmorey, and it was one of the many pieces that she bequeathed to the Queen in 1953.

This diamond and sapphire brooch was Queen Mary’s wedding gift from her new husband’s aunt, Empress Marie Feodorovna of Russia, in 1893. She bequeathed it to the present Queen in 1953, and HM has worn it fairly frequently in the decades since. She often pairs the brooch, with its distinctive sugarloaf sapphire, with outfits in vibrant shades of blue.

This Victorian brooch was a wedding gift from King Edward VII and Queen Alexandra to Queen Mary in 1893. The diamond and turquoise brooch was later inherited by the present Queen, though she only began wearing it frequently in recent years. She most famously wore it for a public broadcast to the nation in the spring of 2020.

This petite cluster brooch features a vivid pink gemstone (often described as a pink sapphire) set in a beautiful diamond frame. The brooch originally belonged to the Queen’s grandmother, Queen Mary. In recent years, it has become one of the Queen’s favorite brooches, appearing at palace audiences, Royal Ascot, and even one outing on Christmas Day!

The third tiara that Mary bequeathed to her granddaughter was her lover’s knot tiara, made in 1913 to resemble one once owned by Mary’s grandmother, Princess Augusta, Duchess of Cambridge. The Queen wore this fairly frequently in the early years of her reign, and then later loaned it to Diana, Princess of Wales and to the Duchess of Cambridge.

This grand tiara was made for Grand Duchess Maria Pavlovna of Russia, wife of Grand Duke Vladimir, around 1870, and then smuggled out of Russia by a British diplomat during the revolution. Queen Mary bought it from Maria Pavlovna’s daughter, Princess Nicholas of Greece and Denmark, in 1921. The tiara was originally hung with pearl drops; Mary had it converted so it could also be worn with drops from the Cambridge emerald collection. The tiara has remained one of the Queen’s most-worn pieces in the decades since she inherited it in 1953.

Elizabeth II inherited this magnificent diamond and emerald negligee necklace, worn by Queen Mary at the 1911 Delhi Durbar, in 1953. The emeralds in the necklace came from the Cambridge emeralds, which had been won by Mary’s great-grandmother, in a German state-sponsored charity lottery in 1818. The marquise diamond pendant is one of the Cullinan diamonds (Cullinan VII, to be precise). Since Elizabeth did not inherit the Delhi Durbar Tiara from Mary—that piece remained with the Queen Mother until 2002—she has generally paired this necklace with the Vladimir Tiara in its Cambridge emerald setting.

In 1905, the largest diamond ever discovered was found in the Cullinan mine in South Africa. Two years later, the enormous diamond was presented to King Edward VII. Over the next year, the 3100 carat stone was cut and polished into nine major stones. In 1910, the new king, George V, ordered that the largest two stones should be set in the Imperial State Crown and the scepter. The next two biggest diamonds, Cullinan III and IV, were made into a brooch. Queen Mary bequeathed the brooch to the Queen in 1953; she has jokingly referred to the enormous diamond brooch as “Granny’s Chips.” Fittingly, the Queen chose to wear this brooch during the celebrations for her Diamond Jubilee in 2012.

The Cullinan V stone is a heart-shaped diamond; Queen Mary had it placed in a lovely brooch setting by Garrard in 1911. (She also sometimes wore it with her honeysuckle tiara, which now belongs to the Gloucesters.) The Queen inherited the brooch in 1953, and she has worn it consistently throughout her reign. It continues to be one of her most-worn brooches today.

The Cullinan VI stone belonged to Queen Alexandra privately; she bequeathed it to Queen Mary in 1925. Mary generally wore it linked together with the Cullinan VIII stone, and it was bequeathed in that configuration to the Queen in 1953.
