5-Ct. Pink Goes For $2.94M At Bonhams London Auction, Sets Record

The 5.03-carat fancy pink diamond

A 5.03-carat, VS1 clarity fancy pink diamond sold for £2.23 million ($2.94 million) at Bonhams London Fine Jewellery on September 26. The sale set an auction world record price with a $583,551 per carat price, overtaking the previous fancy pink per-carat record of $528,021 set at the Sotheby’s Geneva auction in May 2016.

Bonhams UK Director of Jewellery Emily Barber noted, “This was due to a number of factors — its size (it’s exceptionally rare to see a pink over five carats on the market today), its even colour saturation and its extraordinarily elegant cut.”

The overall sale total was £6.94 million ($9.06 million), with 89 per cent lots sold by value.

A fancy-coloured diamond three-stone ring circa 1910, also sold at the auction for £168,750 ($220,526) against its pre-sale estimate of £80,000-£120,000 ($104,546-$156,838).  This featured an old brilliant-cut fancy blue 0.95-carat diamond set between fancy yellow-orange marquise-cut diamonds, weighing 0.51 and 0.56 carats.
