Marilyn Monroe may have popularised the phrase “diamonds are a girl’s best friend”, but it was the “Dancing” 5th Marquess of Anglesey, Henry Cyril Paget, who pioneered the lifestyle. The colourful if controversial British aristocrat—known as Toppy—squandered his inheritance on sparkling jewels, outlandish fashions and flamboyant theatre productions of his own making, running up debts equivalent to £60m before his death in 1905. His wardrobe and jewels were sold in 1904 to pay creditors, with the jewels alone realising £80,000. Yet this 100-carat diamond tiara, no doubt worn by Toppy in his theatre skits (and perchance the odd Tuesday afternoon, just for kicks), until recently remained in the family; Cecil Beaton photographed the 6th Marchioness of Anglesey, Lady Marjorie, wearing it at King George VI’s coronation in 1937. It is priced at £500,000 to £1m, from Hancocks London. The Anglesey Tiara (around 1890). For sale with Hancocks London
