Kate wears Princess Margaret’s ‘signature’ tiara in most unusual way – and for first time

The piece is one of the smaller diadems in the royal collection, with its elegant design and its diamond-encrusted lotus motifs.

Miranda continued: “It is customary for the royals to have pieces of jewellery refashioned into something new, it’s a bit like a royal form of upcycling.”

Princess Margaret received the tiara in 1959 and it became one of the “signature pieces” in her collection.

“Following her death, there was much speculation as to what had happened to the piece until we saw Kate looking beautiful wearing it in 2013.
