A stunning platinum ring featuring a 5.02 carat blue diamond is set to headline Christie’s Hong Kong auction later this month, with an estimated value of up to US $10.3 million (HKD 80 million).
The centerpiece is an internally flawless, fancy deep blue marquise brilliant-cut diamond, graded by the Gemological Institute of America (GIA).
Dating back to 1923, the ring is listed in the auction catalog as “property of a lady,” though further details about the owner remain undisclosed.
This exquisite piece will lead the highly anticipated 124-lot Magnificent Jewels live sale on October 29, alongside a pair of diamond “Oriental Sunrise” earrings.
These earrings showcase two fancy vivid orange yellow diamonds (12.20 carats and 11.96 carats) and share the same US $10.3 million (HKD 80 million) high estimate.
Petra Diamonds sold fewer carats but achieved higher prices earlier this month at its fifth tender of FY 2024, boosted by the sale of an $8.2m blue diamond.
The UK-based miner achieved an average $136 per carat on sales of 362,000 carats for $49m.
Like-for-like figures for its fourth tender, in February, were $112 per carat on sales of 429,000 carats for $48m.
Sales for the year to date are, however, lagging behind FY 2023, at $285m, down 10 per cent down on $316m.
The 14.76ct exceptional color and clarity blue diamond recovered from Cullinan, South Africa, sold for $8.2m, although it was not classified as an “exceptional stone” (over $15m).
Total revenue for Q3 FY 2024 was $66m, down 27 per cent on the previous quarter, due to the lower production and the timing of receipts from the fifth tender.
“Production for the quarter is consistent with the preceding quarter and in-line with expectations.,” said CEO Richard Duffy.
Production guidance for FY 2024 is 2.75m to 2.85m carats.
Earlier this month Petra announced the sale of its loss-making Koffiefontein mine, in South Africa, to Dubai-based Stargems for a nominal sum.
Christie’s has auctioned one of the rarest blue diamonds in the world for a staggering $44 million.
On Tuesday, the stone called the “Bleu Royal” went under the hammer as one of the highlights of the auction house’s Luxury Week sale in Geneva, far outstripping the presale estimate. It is the first time the stone has been sold at auction, having been in private hands for the past half century.
Set into a ring, the 17.61 carat, pear shaped diamond is considered the largest internally flawless vivid blue diamond to have ever come to auction, and had a presale estimate of $35 million. At the sale, it eventually realised $43.8 million, making it the most expensive jewel sold at auction this year.
4.83 ct Fancy Blue Diamond Sells for $8.8 million USD
A 4.83 carat fancy vivid blue diamond ring sold for $8.8m at Christie’s Hong Kong as the Magnificent Jewels sale brought in a total of almost $60m.
The brilliant cut IF Type IIb gem (pictured) was surrounded by fancy-cut diamonds, in a gold setting. It sold between the low and high estimates of $7m to $10.2m.
The blue diamond led the sale, followed by two items which both sold for above their high estimates.
An octagonal step-cut 21.38 carat sapphire in a platinum ring set with tapered baguette cut diamonds sold for $4.5m (high estimate $2.3m).
And an 8.92 carats fancy vivid yellow orange pear modified brilliant cut diamond, in a platinum and gold ring, with pear brilliant-cut diamonds of 1.12 and 1.11 carat, sold for $4m (high estimate $3.8m).
A rare,11.16-carat fancy vivid blue diamond named the “Bulgari Laguna Blu” has fetched slightly more than $25 million at a Sotheby’s Magnificent Jewels sale in Geneva.
The auction house brought the clock back to pre-pandemic times by achieving the best performance since May 2018, with total proceeds of over 76 million Swiss francs (about $85m).
Sotheby’s noted the exceptional blue diamond was put up for auction last and after a four-minute bidding battle between three telephone bidders and one bidder in the room, it eventually found a buyer on the phone.
The sale made of the Bulgari Laguna Blu the most expensive jewel ever sold in Geneva. It is also the largest blue diamond in a Bulgari jewel and the brand’s most valuable gem to ever be put up for sale.
The Bulgari Laguna Blu is a rarity three times over, as it is a blue diamond, a jewel signed by Bulgari, and an unseen and unmodified gemstone.
Bulgari’s global Ambassador, actress Priyanka Chopra, wore the Bulgari Laguna Blu this year’s Met Gala in New York.
The Italian jewelry maker set the oceanic-blue sparkler in a bespoke diamond necklace for actress Priyanka Chopra Jonas, and the stone then was removed and remounted onto a ring—similar to the house’s original 1970s design.
The diamond was initially mounted as a ring by Bulgari for a special commission by the original owner. It was sold in 1970 and it’s now part of a necklace.
A rare 11.16 carats fancy vivid blue diamond could fetch between 22 to 25 million Swiss francs ($24 to $28 million) when it goes under Sotheby’s hammer next week in Geneva.
Named the Bulgari Laguna Blu, the pear-shape cut diamond boasts a rich blue hue that the auction house qualifies as “extraordinary” and “mesmerizing”.
It is the highest grade blue diamond ever graded by the Gemological Institute of America (GIA) and the third-largest pear-shaped fancy vivid blue diamond to ever go for sale on an auction, according to Olivier Wagner, head of jewellery at Sotheby’s Geneva.
The gem, first exhibited at the famous Met Gala fashion show in New York on Monday, is expected to attract the interest from global collectors.
Sotheby’s will sell a group of eight fancy-blue diamonds from De Beers across its global Magnificent Jewels auctions, expecting the set to bring in more than $70 million.
The stones are cut in various shapes and range from 1.22 to 11.29 carats, with a total weight of 32.09 carats, Sotheby’s said last week. The polished originates from five rough blues that De Beers and Switzerland-based manufacturer Diacore purchased jointly from Petra Diamonds in November 2020. Diacore cut and polished those stones into eight diamonds over the past two years.
Sotheby’s will offer three stones from the eight-piece group, called The De Beers Exceptional Blue Collection, this year. The first, a cushion brilliant-cut, 5.53-carat, fancy-vivid blue diamond will go under the hammer at the Magnificent Jewels and Noble Jewels sale in Geneva on November 9, with a high estimate of $15 million. Meanwhile, the December 7 Magnificent Jewels sale in New York will feature a cushion brilliant-cut, 3.24-carat, fancy-vivid blue, internally flawless diamond estimated at up to $8 million. That jewel will be joined by a cushion-cut, 2.08-carat, fancy-intense-blue diamond with an upper price tag of $1.5 million.
“I have remained in awe of the De Beers Exceptional Blue Collection since the first moments I set eyes on it,” said Olivier Wagner, head of Sotheby’s Magnificent Jewels auctions in Geneva. “The market for colored diamonds and precious gemstones has never been stronger. [The diamonds] will, I am sure, captivate all collectors of exceptional gemstones.”
Sotheby’s will sell the remaining five diamonds at its spring 2023 Magnificent Jewels auctions. Those include a step-cut, 11.29-carat, fancy-vivid-blue estimated at up to $50 million; a step-cut, 4.13-carat, fancy-intense-blue expected to go for up to $3.5 million; and a cushion brilliant-cut, 3.10-carat, fancy-vivid-blue diamond with a high price of $5 million.
In April, Sotheby’s sold another De Beers blue diamond: a step-cut, 15.10-carat, fancy-vivid-blue, internally flawless stone that went for $57.5 million in Hong Kong.
