• Key items of Queen Elizabeth II’s jewellery including the Diamond Diadem and the Delhi Durbar necklace go on display in Buckingham Palace’s State Rooms from tomorrow as part of the palace’s Summer Opening. Created for the coronation of King George IV in 1821, the Diamond Diadem is set with 1,333 brilliant-cut diamonds, some of which are set in the form of a rose, a thistle and two shamrocks, the national emblems of England, Scotland and Ireland. The diadem, which was inherited by Queen Victoria in 1837 and passed down to the current Queen, will be displayed alongside the official portraits of the Queen taken by photographer Dorothy Wilding just weeks after the Accession (the portraits were later were used as the basis of the Queen’s image on postage stamps from 1953 until 1971, as well as providing the official portrait of Her Majesty sent to every British embassy throughout the world). The Delhi Durbar necklace, meanwhile, incorporates nine emeralds originally owned by Queen Mary’s grandmother, the Duchess of Cambridge, as well as an 8.8 carat diamond pendant cut from the Cullinan diamond – the largest diamond ever found. It was made for Queen Mary as part of a suite of jewellery created for the Delhi Durbar in 1911. The Queen inherited the necklace in 1953 and wore it in a portrait sitting for Dorothy Wilding in 1956 – thought to have been their last sitting together before Wilding’s retirement in 1958. The jewellery, a special display to mark the Platinum Jubilee, can be seen at the Summer Opening of the State Rooms at Buckingham Palace, the first time the palace has been open to the public in three years, until 2nd October. Admission charge applies. For more, see www.rct.uk.

• An exhibition exploring how design can enhance our experience of ageing has opened at the Design Museum. The Future of Aging includes a selection of prototypes, sketches and research from projects that are being developed by Design Age Institute and its partners. They include a self-balancing, two-wheeled personal electric vehicle known as ‘The Centaur’, a hands-free cargo-carrying robot called Gita, and a digital ‘audioscape’ app that uses the sound of birdsong to engage visitors with their hearing health. The free display also includes a long-term participatory project that explores opportunities for an intergenerational garden at the museum and two new film commissions which showcase stories and experiences of later life. Runs until 25th September. For more, see https://designmuseum.org/exhibitions/the-future-of-ageing.
