The world’s largest flawless briolette diamond will hit the auction block at Christie’s Hong Kong Magnificent Jewels sale on May 28. Estimated to fetch between $8.5 million and $12.5 million, the fabulous 75.36-carat, D-color wonder is part of a pendant necklace that includes a marquise-cut purplish-pink diamond suspended above the briolette. Stations of smaller briolettes adorn the 18-karat white and rose gold neckchain, which is adjustable.
The briolette diamond is so perfect that it earned the top quality grade of Type IIa from the Gemological Institute of America. The grade reflects its flawless clarity, excellent polish, chemical purity and exceptional transparency. Other famous Type IIa diamonds include the 530.2-carat Cullinan and the 105.6-carat Koh-i-noor.
Legendary diamond cutter William Goldberg started with a 160.5-carat rough diamond and lost more than half the stone’s weight as he shaped it into the world’s largest and most perfect briolette — an symmetrical shape that resembles a water drop.
Christie’s jewelry specialist Chiang Shiu-Fung told the press that the headliner of the May 28 auction is exceptionally rare. Over the past six years, he has seen only one similar item at a Christie’s auction and that briolette was “only 30-something carats.”
Comprising more than 290 lots, the May 28 Christie’s auction is expected to generate more than $74 million in sales.
