The bling dynasty! Joan Collins makes £200k for charity by selling her treasured diamond jewellery 

Diamonds are forever – but Dame Joan Collins owns so many she put a generous number of sparklers up for auction to raise money for charity.

The Dynasty actress, 87, parted with five pieces from her extensive jewellery collection for yesterday’s sale – and made more than £200,000.

A Van Cleef & Arpels diamond brooch dating from about 1930 fetched £122,000 – £100,000 more than its estimate.

The delicate piece, fashioned in a corkscrew to resemble a ribbon, had been estimated by Bonhams in London to make between £15,000 and £20,000.

It outsold a 60.5-carat diamond necklace that Dame Joan bought in 1985 when she was starring in Dynasty as Alexis Carrington Colby. 

It was predicted to be the biggest seller, but eventually sold for £69,000.

A pair of pendant earrings was expected to fetch between £2,000 to £3,000 but sold for five times that at £15,000, a collar went for £10,000 – nearly double its estimated value – and a pair of ruby and diamond pendant earrings sold for £7,000.

A portion of the proceeds will go to the Shooting Star Children’s Hospices, of which Dame Joan is a patron. 

‘The fabulous thing about jewellery is how extraordinary it makes you feel,’ she said. 

‘These pieces of jewellery have brought me so much joy over the years and I felt it was time for others to experience this.

‘I am also delighted to support The Shooting Star Children’s Hospices – the charity is vitally important.’
