Happy Birthday to Emma Thynn, the Marchioness of Bath, who turns 40 today! The glamourous Socialite and Model is the first mixed race Marchioness in British History, and has often worn this magnificent Diamond Tiara which is a spectacular heirloom of the illustrious Thynn Family!
Created in 1862 for the 4th Marquess and Marchioness of Bath, the Diamond Tiara is composed of ornate diamond festoons over a base of diamond hoops, which is made of diamonds taken from older family heirlooms.
One of the earliest images of the Tiara being worn was in the early 1910s, when it was worn by the 5th Marchioness of Bath for a portrait, which was rediscovered at Longleat House recently.
In 1938, the Tiara was worn by Daphne, then Viscountess Weymouth, when she and the Marquess joined Princess Marina, Duchess of Kent for a Ball at the newly restored Assembly Rooms in Bath. As the 5th Marchioness had passed away, she also likely wore the Tiara for the Coronation of King George VI in 1937.
The following year, Viscountess Weymouth wore the Tiara again for a Gala Performance at Covent Garden, held during the French State Visit in 1939, which appears to be her last prominent appearance, since the Marquess and Marchioness divorced right before the Coronation of Queen Elizabeth II in 1953, with the Marquess riding alone in the State Coach with footmen in yellow livery.
Lord Bath remarried the following month, but the Tiara does not seem to have been publicly worn by the next Marchioness of Bath nor by her successor, but it does seem that it was worn by their daughter, Lady Silvy Thynne, for her wedding to Iain McQuiston, the brother of the current Marchioness, in 1989.
The Tiara remained publicly unworn until 2013, when Emma McQuiston married the then Viscount Weymouth at Longleat amid disapproval from his family.
When she was Lady Weymouth, the Diamond Tiara was not confined to formal occasions but appeared for numerous parties held at Longleat House over the years, including for Lady Weymouth’s 30th Birthday in 2016.
After becoming the Marchioness of Bath in 2020, the Diamond Tiara was worn when Edward Enninful, the editor-in-chief of British Vogue, celebrated his Wedding at Longleat.
A few years ago, the Tiara, along with a Diamond Rivière, and the Marchioness’ Wedding Gown went on display at Longleat.
The Marchioness of Bath has continued to wear the Diamond Tiara There is no doubt we will continue to see this spectacular Family Heirloom for years to come!
