The famous reclusive heiress Huguette Clark owned a big cushion brilliant-cut fancy vivid pink diamond. Introduced as the highlight of her jewels, it remained unsold at auction in 2012 on a lower estimate of $ 6M.
Ancient diamonds have a potential for improvement. For example, Graff removed 4 carats from his Blaue Wittelsbacher to improve its clarity.
In her estate, the Clark diamond weighed 9.00 carats with a SI1 clarity that was indeed not exciting.
It is now offered by Sotheby's on May 12 in Geneva. It has been reduced to 8.72 carats to improve its clarity to VS2, guaranteed by GIA. Mounted on a ring between two small D color diamonds, this gem is estimated 13,65M CHF corresponding to US $ 14M, lot 460.
Its provenance was also researched and it received the name of Historic pink. This diamond had been bought by Dreicer at the auction of the estate of Mathilde Bonaparte in Paris in June 1904.
