An oval diamond of over 88 carats sold by Sotheby’s for 13.8 million dollars in Hong Kong ♦ ︎
Big diamonds are forever, at least in auctions. The spectacular new confirmation comes from Hong Kong, where a spectacular oval brilliant diamond of 88.22 carats, D Color, Flawless, Type IIa, perfect according to every critical criterion, was sold at the Magnificent Jewels auction for 13,8 millions dollars, or 12.3 million euros. The diamond was one of only three oval diamonds of over 50 carats auctioned, and the largest for over five years. It was bought by a private Japanese collector, who admired it when the stone was on display in Japan, in the usual road show that precedes sales of this type.
After paying a similar sum, the collector took the satisfaction of baptizing the diamond, now called Manami Star. Manami is the name of the eldest daughter.
The diamond was contested by three bidders and started with a valuation between 11.2 and 12.7 million dollars, which it exceeded. The price per carat is $ 156,150.
We were thrilled to handle a diamond of such rarity, which now takes its place in the roster of top white diamonds to have come to the market here at Sotheby’s Asia. Three clients from the region competed for the stone – testament to the strong demand for diamonds of this quality in this part of the world. At 88.22 carats, this lucky stone now carries the name of the fortunate child whose father has chosen to give it her name. A happy moment in the journey of one of the earth’s greatest, oldest treasures.

Perfect according to each critical criterion, the diamond has reached the highest rankings based on each of the standards with which the quality of a stone (the four Cs) is judged. The diamond is the color D (the highest grade for a white diamond); of exceptional clarity (it is completely flawless, both internally and externally), and has an excellent gloss and symmetry. As with the Koh-i-noor diamond (also oval) and the Cullinan I, which are part of the British Crown Jewels, the stone belongs to the rare sub-group which includes less than 2% of all gemmed diamonds, known as Type IIa . The diamonds of this group are the most chemically pure type of diamond and often have an exceptional optical transparency.
Finding a rough diamond that allows those who cut it to shape a stone over 80 carats is very rare. The 242-carat rough stone that produced the diamond was discovered in Botswana in the Jwaneng mine, a mine owned by De Beers and the Botswana government, known for the production of high quality raw materials. After its discovery, the rough diamond was cut and polished for months. Given the elongated shape of the rough stone, the oval shape was chosen to preserve the greatest amount of weight. A great skill and precision was needed to cut a stone of this importance: a level of experience and mastery possessed by only a small handful of cutters from all over the world.
In the same auction, a ring with sapphire and diamonds was sold for 2.4 million dollars, another ring with pear-cut diamond and pink diamonds was sold for 1.7 million, while a necklace of diamonds and emeralds by Van Cleef & Arpels found a buyer for $ 1.1 million. Also noteworthy is a pair of diamond and sapphire earrings, also worth over a million US dollars, as well as an emerald and diamond ring. Federico Graglia
