3.81-Ct. Blue Diamond Kicks Off Fall for Bonhams London
The oval-cut fancy intense blue diamond could sell for as much as $2.4 million at the auction house’s upcoming Fine Jewellery sale.
This 3.81-carat oval-cut fancy intense blue diamond is expected to be the top lot at Bonhams’ Sept. 20 Fine Jewellery sale in London.
London--When Bonhams London kicks off its autumn auction season next month, it will do so with a number of high quality blue stones.
Leading the Fine Jewellery sale, which is scheduled for Sept. 20, will be an oval-cut 3.81-carat fancy intense blue diamond. Coming from a private British collection, the stone is expected to sell for $1.7 million to $2.4 million.
Bonhams currently holds the price-per-carat world auction records for both a fancy deep blue diamond ($1.77 million per carat) and a fancy grayish-blue diamond ($730,000 per carat).
Also topping the London sale is a pair of earrings featuring cushion-shaped Kashmir sapphires weighing just under 9 carats surrounded by old brilliant-cut diamonds. The earrings are expected to garner as much as $790,000.
An 11-carat marquise-cut diamond set in a six-claw ring and a 13.77-carat brilliant-cut diamond ring from J. Roca both have a pre-sale high of $330,000.
Other lots expected to top the sale include a pair of sapphire and old brilliant-cut diamond earrings ($200,000 to $260,000) and a necklace and earrings suite featuring cabochon rubies and diamonds. It could garner between approximately $130,000 and $200,000.
This ring from J. Roca features a 13.77-carat brilliant-cut diamond of I color and VVS2 clarity between shoulders set with trios of graduated baguette-cut diamonds. It is estimated to sell in the range of $240,000 to $330,000.
A marquise-cut 11-carat diamond set in a six-claw 18-karat gold setting could go for as much as $330,000.
The necklace in this suite features an articulated geometric chain of diamonds alternating with oval cabochon rubies, suspending a large scrolling cartouche pendant set with oval cabochon rubies and diamonds. The earrings are created in a similar style. All pieces are convertible--the necklace detaches to form bracelets, a pendant and a brooch, while the earrings convert to single pair of ear or dress clips. The set is predicted to garner in between $130,000 and $200,000.
This pair of earrings features two cushion-shaped Kashmir sapphires weighing 8.97 carats and 8.93 carats, each surrounded with old brilliant-cut diamonds and an old brilliant-cut diamond surmount. They’re expected to garner between $530,000 and $790,000.
A pair of earrings, each set with a cushion-shaped sapphire weighing 4.16 and 5.01 carats and a border of old brilliant-cut diamonds, could sell in the range of $200,000 to $260,000.
Additional highlights include an 18.77-carat oval-cut Sri Lanka sapphire ring with a brilliant-cut diamond border and pave-set diamond shoulders, estimated to garner as much as approximately $110,000.
A 12.50-carat Colombian emerald and diamond cluster ring circa 1960 also will go up on the block at the auction house’s New Bond Street salesroom next month, with a pre-sale estimate high of $53,000, as will diamond pendent earrings circa 1830 weighing 3.02 and 3.25 carats, E and F in color and Type IIa clarity. They have a pre-sale range of $40,000 to $53,000.
