(IDEX Online) - An exceedingly rare fancy pink diamond weighing 5.03 carats will headline Bonhams London Fine Jewellery sale on September 26.
The square-cut fancy pink diamond, VS1 clarity, is estimated to sell for at ?600,000- ?800,000 ($780,000-$1,000,000).
Emily Barber, Director of Jewellery at Bonhams UK, said: "This pink diamond, offered at auction for the first time, possesses an exceptional combination of characteristics.
"It is extremely unusual to find a pure pink diamond, of even saturation, with no secondary component colors, weighing over 5.00 carats. This diamond's significant size and elegant, unmodified square cut, coupled with its high clarity grade distinguishes it further. It is of extraordinary beauty."
Bonhams will also be offering a fancy-colored diamond three-stone ring, circa 1910, for sale. The central old brilliant-cut fancy blue diamond, weighing 0.95 carat, is set between fancy yellow-orange marquise-cut diamonds, weighing 0.51 and 0.56 carats, and is estimated at ?80,000-120,000.
A selection of bracelets, necklaces, brooches and rings from some of the biggest names in jewelry including Cartier, Van Cleef & Arpels, Bulgari and Chopard will also go under the hammer in the sale.
