Brooch that showed off her very playful sense of style

LOOKING particularly stylish at an America’s Cup Ball at the Grosvenor House Hotel in 1986, Diana, by then hitting her fashion stride, decided to pin a diamond brooch to a velvet choker and wear it as a necklace.

Little is known about the brooch, an arrow shape featuring diamonds and sapphires. Yet the remainder of her look was certainly eye-catching.

Her flamenco- style dress was by Murray Arbeid, her earrings were faux onyx stones from her favourite costume jeweller, Butler and Wilson, and she wore mismatched gloves (one black and another red), setting the tone for her most fashion-forward years.
