Sotheby’s Blue Diamond goes to an international diamond merchant in further support of the colored diamond market, according to Bloomberg:
Moussaieff Jewellers Ltd.’s founder Alisa Moussaieff paid HK$49.9 million ($6.4 million) for a 5.16-carat blue diamond at a Hong Kong auction, beating Asian rivals with a price she says is less than the gem’s real worth.
Moussaieff, 80, says the fancy-vivid, internally flawless gem has a market value of about $1.5 million per carat and that she would have raised her bid had her rival persisted. A blue diamond of that size and caliber is so rare that it’s worth about $2 million a carat and high-street stores like Moussaieff could ask for $3 million, said Donald May, a Hong Kong-based jeweler who was also at the sale. A carat is a fifth of a gram.
“It’s a bargain and I got it at this price because everyone was asleep,” Moussaieff said in an interview. Her London-based boutique will change the gem’s mounting and offer the stone “to discerning clients, possibly in Asia,” she said. […] The auction record for a blue diamond was set by Hong Kong property tycoon Joseph Lau in May with his purchase of a 7.03- carat gem in Geneva for 10.5 million Swiss francs ($9.8 million).
