Sotheby’s has announced that one of the world’s most precious diamonds, The Pink Star, will return to auction in Hong Kong on April 4. The 59.60-carat gem is estimated to be worth over HK$468 million, and is the largest ever, internally flawless, coloured diamond.
“The extraordinary size of this 59.60-carat diamond, paired with its richness of colour, surpasses any known pink diamond recorded in history” says David Bennett, Worldwide Chairman of Sotheby’s Jewellery division. The oval-shaped, mixed cut diamond has received the highest colour and clarity grades from the Gemological Institute of America, and has been classified as a Type IIa diamond, a rare subgroup of chemically pure makeup and extraordinary optical transparency. It took over two years of meticulous carving and polishing to transform the 132.5-carat rough diamond into the stunning treasure it is today.
