This weekend, as Queen Elizabeth II celebrates her platinum jubilee, marking a remarkable 70 years of public service, Sotheby’s London will join the festivities with a series of talks and exhibitions culminating in an auction of British art featuring some of Her Majesty’s favorite artists.

On view as part of the events will be an exhibition of stunning tiaras including the Spencer Tiara worn by Princess Diana on the occasion of her wedding to Prince Charles and at several other Royal events.

With a “central heart-shaped motif set with diamonds flanked by continuous running scrolls,” according to the auction house, the headpiece is instantly recognizable.

Nearly 50 pieces, including an emerald tiara that belonged to Queen Victoria alongside examples from throughout history, will also be on view.

“The Queen’s Jubilee celebrations have given us the perfect opportunity to put on public display an outstanding selection of tiaras from noble and royal provenance, many of which haven’t been exhibited in decades,” Kristian Spofforth, Sotheby’s head of Jewelry in London, said in a statement.

“The sourcing of these jewels has been a labor of love, resulting in an exhibition that showcases the best iterations within the tiara style register, through some of its most famous incarnations, including the much-loved and photographed Spencer Tiara,” Spofforth added.

Other events in the program include a talk with Joanna Lumley and writer Robert Hardman exploring the Queen’s legacy and a series of performances, together titled “Escaping the Canvas,” produced in collaboration with the Royal Academy of Dramatic Arts.

A discussion about Oluwole Omofemi’s new portrait of the Queen between the artist and the Tatler‘s art editor, Helen Rosslyn, is also on the schedule, as is a conversation between artist Magdalene Odundo and Tristram Hunt, the director of the V&A.

Events run through June 10 and booking is required.
