Nilesh Rakholia, Director at ABELINI Jewellery, told Express.co.uk: “Now as a tiara, its strong art deco influences are clear through the prominent arches and fans.

“Since its creation, it has been worn by the ever-glamorous Princess Margaret and the Duchess of Cambridge.”

The tiara was also worn at a royal wedding in the 1990s.

Serena Stanhope wore the creation in 1993 for her wedding to Viscount Linley, Princess Margaret’s son and the future Earl of Snowdon.
