Princess Margaret might have referred to herself as "the spare" for much of her life but when it came to royal wedding bling, there was no way the Queen's little sister was going to be outshone. For her marriage to Antony Armstrong-Jones, at Westminster Abbey on May 6, 1960, Margaret wore the stunning Poltimore tiara. Never mind something borrowed, it seems this was the ultimate wedding day gift to herself.
Margaret acquired the tiara in 1959 when it came up for auction. No one is quite sure who handed over the cash but it has long been rumoured that the princess purchased herself. It was made in the 1870s for Florence, Lady Poltimore and in 1911, her daughter-in-law wore it at the coronation of King George V.
This tiara is actually a closed circlet of diamonds and it can also be broken down into a necklace and brooches, just to keep things practical. It dazzled everyone when Margaret debuted it on her wedding day and It was sold at auction for almost £1 million after her death.
