75-Carat Briolette Diamond On A Necklace May Fetch $12.5 Million



Christie’s Hong Kong Magnificent Jewels sale on May 28 will feature the biggest briolette diamond that has ever appeared at auction, according to the auction house. The 75.36-carat diamond is part of a pendant necklace that includes a marquise-cut purplish pink diamond suspended above the briolette.

The briolette has been graded as D color and type IIa, indicating its internally flawless clarity, excellent polish, highest level of chemical purity and exceptional optical transparency. The two diamonds are joined to a briolette diamond neck chain mounted in 18k rose and white gold. The necklace is estimated to fetch $8.5 to $12.5 million.

The sale at the Hong Kong Convention and Exhibition Centre also includes two other standout pieces



* An emerald and diamond necklace mounted by Boucheron in the 1950s. Its eight emeralds of Colombian origin are set with a line of graduate old European and cushion-shaped diamonds each weighing 10 carats or above alternating with baguette-cut diamonds, according to the auction house. The center stone shows no indication of clarity modification and the other emeralds are all in well saturated green color, which further elevates the necklace’s value, according to the auction house. The estimate for this piece is $3 to $5 million.

* A ruby and diamond ring by James W. Currens for Faidee. Its centerpiece is a natural oval-shaped ruby of 8.88 carats with a richly saturated and homogenous color and a high degree of transparency, is joined by pear and marquise-cut diamonds, according to the auction house. The ruby is of Burma (Myanmar) origin, with no indications of heating and this color appearance is described in the trade as “pigeon blood,” the most desirable red color for rubies. Its estimate is $2.3 to $3.5 million.

In total, more than 290 jewels will be offered. It is estimated to realize in excess of $74 million. It includes signed pieces from world-class jewelry houses and fine jewels with distinctive shapes, structures and color combinations.
