Though this piece was once said to date from the 18th century, it actually seems to be a combination of pieces of varying ages. The center element was a wedding gift from Lady Sarah Spencer to Cynthia, Viscountess Althorp (Diana’s grandmother), in 1919. Garrard was asked to create four matching pieces in 1937 to add on. The oldest bits are at the ends; these are said to have come from a tiara once belonging to Frances, Viscountess Montagu and left to Lady Sarah Spencer in 1875. The full current appearance apparently dates from around 1935.
Diana’s wedding to Charles, the Prince of Wales in 1981.
As the Princess of Wales, Diana continued to wear her family’s tiara. The Queen had given her the Cambridge Lover’s Knot Tiara to use, but the Spencer was lighter and easier to wear. Plus, you can’t argue with wanting a second option, or wanting to show your pride for your own family.
The design of this one makes it easy to love. It’s feminine - girlish, really - and whimsical, as though it might once have been a doodle around the edges of a fairy tale page. And it made a wonderful match for Diana’s image as a young princess in her poufy evening gowns. I think it did her a bit of a disservice as she matured, though; it almost seems ironic to wear such a dreamlike design in a life that was quickly and publicly losing its dreamy sheen.
