A 12-carat blue diamond proved there’s still demand for colored diamonds when it went for well above its pre-sale high estimate at auction Thursday July 9.

Christie’s Magnificent Jewels auction in Hong Kong marked one of its first live sales for the house since the onset of the pandemic.

The auction was led by a 12.11-carat internally flawless marquise-cut fancy intense blue diamond, which sold for $15.9 million, compared with its pre-sale estimate of between $8 million and $12 million, after 15 minutes of bidding, according to Christie’s.

Following behind the blue diamond at No. 2 in the auction results was a 19.53-carat Burmese star ruby pendant, with ruby and diamond accents, by Edmond Chin for Etcetera.

The piece garnered $2.7 million at auction Thursday July 9, falling within its pre-sale estimate range.

At No. 3 was a 17.95-carat cut-cornered rectangular step-cut diamond ring accented with tapered baguette-cut diamonds, which went for $1.6 million.

Tied at No. 4 was another blue diamond ring, this one a 2.08-carat fancy intense blue marquise brilliant-cut, and a necklace featuring two oval-cut sapphires weighing 12.81 carats and 6.50 carats.

Both of those pieces went for above their pre-sale estimate high when they sold for $1.5 million Thursday.
