This very rare pink diamond, all 5 carats of it, will be set for auction at Christie’s by jeweller, Graff. The ring is currently displayed in New York and will be auctioned off in Hong Kong on the 1st of December there. The site was chosen because Christie notes that the dollar market is more improved there.
The diamond, mined from South Africa, is expected to fetch around $1M per carat.
