Margaret's jewels make almost £10m
Jewellery once owned by the Queen's sister, Princess Margaret has raised almost £10 million at an ongoing two-day auction.
So far, £9,597,680 has been raised, which will go towards paying Inheritance Tax on the late Princess's estate and will also go to charities, including the Princess Margaret Fund at the Stroke Association.
Items that have already gone under the hammer include her wedding tiara which sold for £926,400. Margaret's silver, furniture and works of art will be auctioned off later.
Helen Molesworth, a specialist at Christie's jewellery department who researched the history of the Princess's jewellery, described the auction as a "sale of a lifetime".
She said: "This is a one-off for my career, this is a sale of a lifetime. For me this is the epitome of the personal side of the Royal Family.
"We have the combination of Royal provenance and glamour which have a wonderful appeal to the British public."
Some of the pieces sold for 100 times their estimated value as jewellery collectors and fans of British royalty battled in the sale room to own one of her cherished jewellery items.
At the height of the sale around 1,000 buyers were packed into five sales rooms. Before the event started, 1,000 people left bids - and there were 500 collectors making bids by phone.
Star lots included a delicate Fabergé clock, a gift from Margaret's grandmother Queen Mary, which fetched £1,240,000, the highest price of the night, and a ring designed by the Princess featuring three rubies surrounded by diamonds, which made £299,200 despite an estimated price of up to £20,000.
The collection included pieces that were inherited, given or personally acquired by the Princess, who died in 2002, and reflected her celebrated style and elegance.
But the highlight of the night was Margaret's head jewellery the Poltimore tiara, which was originally created by Garrards in 1870 for Lady Poltimore, the wife of the second Baron Poltimore.
The Princess wore it on several occasions, including at her wedding to Lord Snowdon and, in its alternative form, as a diamond fringed necklace and scroll brooches prior to their marriage.
Bidding for this unique item was brisk starting at £200,000 and soon reaching £600,000 before one persistent buyer finally saw the hammer fall on her price.
Christie's said a private Asian buyer bought the Poltimore tiara while the Faberge clock went to an anonymous buyer.
