This tiara has been worn by the Queen Mother when she was still the Duchess of York, Princess Margaret and Serena Stanhope on her wedding to Viscount Linley.



From the Official Royal Wedding Site:

The veil is made of layers of soft, ivory silk tulle with a trim of hand-embroidered flowers, which was embroidered by the Royal School of Needlework.  The veil is held in place by a Cartier ‘halo’ tiara, lent to Miss Middleton by The Queen.  The ‘halo’ tiara was made by Cartier in 1936 and was purchased by The Duke of York (later King George VI) for his Duchess (later Queen Elizabeth The Queen Mother) three weeks before he succeeded his brother as King.  The tiara was presented to Princess Elizabeth (now The Queen) by her mother on the occasion of her 18th birthday.
