Qatari Royal Family in Court over Idol’s Eye Diamond

A legal battle over the Idol’s Eye, a 70.21 carat very light blue, eye shaped Golconda diamond, began on Monday (11 November) at the High Court, London.

Two branches of Qatar’s royal family are in dispute over the value of the gem – which could be anywhere between $10m and $27m.

The disagreement is between Qipco, a private investment company run by art collector Sheikh Hamad bin Abdullah al-Thani – a cousin of Qatar’s ruler Sheikh Tamim bin Hamad Al Thani – and Elanus Holdings, a company linked to the family of former culture minister Sheikh Saud bin Mohammed Al Thani.

Elanus loaned the diamond to Qipco in 2014 for 20 years, with an option to buy but the two sides disagree over the value of the stone. It is reported to be worth at least $10m, but according to a Reuter’s report, Elanus’s diamond expert has valued it at $27m.

Qipco says Elanus offered to sell the gem in February 2020, but then pulled out. Elanus disputes this.

Qipco is asking the High Court to force Elanus to go through with the sale.

The Idol’s Eye has a long and complex history. It was recovered in 1600 in the Kollur Mine, part of the Golconda Sultanate in southern India, was initially owned by Prince Rahab of Persia, and was auctioned by Christie’s London in 1865.

It has changed hands many times and has, at various stages, been owned by Harry Winston and Laurence Graff.

5 carat Blue Diamond with $10m US Estimate

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.

Blue and Pink Diamond Ring Fetches $3.7m

A “Toi et Moi” ring featuring blue and pink diamonds – both over 5.0-cts – sold for $3.7m (£3m) almost double its high estimate, at Bonhams London.

The ring was crafted and signed by Mouawad, the Geneva-based jeweler to royalty and high society, which was founded in 1890. It carried a pre-sale estimate of $1.3m to $1.9m (£1m to £1.5m).

The radiant-cut fancy intense blue diamond, weighing 5.03 carats, is obliquely-set with a radiant-cut fancy purple-pink diamond, weighing 5.13 carats. The gallery and shoulders are pave-set with brilliant-cut diamonds of pink and blue tint.

The 113-lot sale, on 13 June, made a total of £6,590,562, with 78 per cent sold by lot and 99 per cent sold by value.

IDEX Price Report for 1 May: Prices Show Signs of Stabilizing

A diamond held by dop is polished on rotating automatic cast iron lap

Prices showed signs of stabilizing during April, with an even mix of increases and decreases in many sizes, especially fancy cuts. Overall there were more clusters of price rises than we have seen of late.

It’s too early to positively identify a clear upward trend, but the “end of the lab grown boom” is arguably having an impact. Lab grown prices are now so low – in some case just 10 per cent of natural – that many jewelers are opting not to stock them in inventory and are only buying them on consignment.

In addition the G7 sanctions, in place since 1 March, are now starting to bite, and to slowly push up prices.

They have effectively restored the De Beers monopoly, although its rough production is down by almost a quarter so far this year (as is Rio Tinto’s) and rough sales remain sluggish (down 18 per cent on last year). Meanwhile polished exports from India fell by 27 per cent during March to $1.2bn

Petra’s Prices Boosted $8.2m Blue

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 sells rare blue diamond for over $40m USD

The 17.61 carat, pear-shaped Bleu Royal diamond, set in a ring, fetched $43.8 million, they said.

It is the “largest internally flawless fancy vivid blue gem” ever to appear for sale in auction history, Christie’s said.

Part of a private collection for 50 years, it was the first time the Bleu Royal was sold at an auction.

“This diamond is amongst the rarest to have been unearthed,” the auction house said in a statement.

Christie’s said only three fancy vivid blue diamonds over 10 carats had appeared for sale in its 250-year auction history, in 2010, 2014 and 2016.

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.

A Rare 17.61 Carat Blue Diamond Is Expected to Sell for Up to $50 Million

While colorless diamonds are the most popular center stones for engagement rings, colored stones are a unique choice that will set your sparkler apart. These gemstones are just as durable as regular diamonds, but they display high levels of brilliance and shine that you can’t find elsewhere. On November 7, 2023, Christie’s Geneva will be auctioning off a colored diamond as part of its “Magnificent Jewels” auction and the rock going on sale is incredibly valuable and one of the “rarest to have been unearthed,” according to Christie’s. The diamond, dubbed “Bleu Royal,” is 17.61 carats and is expected to sell for $35 million to $50 million, per the auction house. “‘Bleu Royal’ is the largest internally flawless fancy vivid blue gem ever to appear for sale in auction history,” Christie’s said in a press release.

The pear-shaped stone with a rich blue color has been part of a private collection for the last 50 years. This is the first time the gem will appear in an auction. “This is a true miracle of nature,” Christie’s International Head of Jewellry Rahul Kadakia said. “Over our 257 year long history, Christie’s has had the privilege of offering the world’s rarest gems at action, and ‘Bleu Royal’ continues this tradition. We are proud to offer collectors the opportunity to own a diamond fit for royalty.”

Ultra-rare Bulgari Laguna Blu diamond sells for $25 million

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.

Bulgari Laguna blue diamond could fetch $28m in auction

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.

De Beers Blue Diamond Fails to Sell at Sotheby’s

   

             5.53 carat De Beers blue diamond

A blue diamond weighing 5.53 carats failed to find a buyer at Sotheby’s Geneva on Wednesday despite being billed as the star of the auction.

The cushion brilliant-cut, fancy-vivid-blue diamond is part of an eight-piece group called the De Beers Exceptional Blue Collection, which Sotheby’s has spread between its various Magnificent Jewels sales. No bids matched the stone’s threshold price for sale, according to a post-auction report by the Fancy Color Research Foundation (FCRF). The piece carried a presale estimate of $11 million to $15 million.

“The blue is an exceptional stone in every sense,” Sotheby’s told Rapaport News Thursday. “It attracted significant interest prior to yesterday’s sale. While we didn’t get to see it sell in the room last night, we are confident it will find a new home very soon.”

Meanwhile, a number of items set records at the November 9 sale, including a 20.16-carat sapphire and diamond ring from Cartier. That piece, which fetched $2.8 million against a high estimate of $2 million, saw a record price per carat for any blue sapphire of Burmese origin ever sold at auction. A 20.58-carat, pink sapphire ring also broke the record for per-carat price, bringing in $1.9 million, or $91,690 per carat, well above its $808,368 upper price tag. A pink sapphire and diamond brooch weighing 92.01 carats by Jean Schlumberger sold for $1.8 million, outstripping its $505,278 high estimate and setting a record price for a piece of jewelry by the designer.

Another notable item at the sale was a pair of unmounted oval-cut, D-flawless diamonds weighing 20.03 and 20.19 carats. The duo fetched $4.2 million, within estimates. A step-cut, 33.13-carat, D-color, VVS1-clarity diamond ring by Cartier brought in $2.9 million, also within its expected range.

The entire Geneva Magnificent Jewels auction garnered $50 million. Sotheby’s will offer two more blue diamonds from the De Beers collection at its upcoming New York Magnificent Jewels sale on December 7.

Collection of Blue Diamonds to Fetch Over $70M

 

The eight De Beers blue diamonds.

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.

Sotheby’s Rakes In $57.5M for De Beers Blue

A record blue diamond co-owned by De Beers far outstripped its presale estimate in a stand-alone sale at Sotheby’s in Hong Kong, garnering HKD 450.9 million ($57.5 million), the auction house said Wednesday.

The 15.10-carat De Beers Cullinan Blue diamond

The step-cut, 15.10-carat, fancy-vivid-blue, internally flawless stone, called the De Beers Cullinan Blue, is the largest of its color to appear at auction. The stone, which sold to an unnamed buyer, had been expected to fetch up to $48 million.

Petra Diamonds discovered the 39.35-carat rough in April 2021 at its Cullinan mine in South Africa. In July, De Beers and Diacore bought the stone for $40.2 million, and Diacore manufactured the piece into the final polished.

To date, only five blue diamonds weighing more than 10 carats have come to auction, none of which has exceeded 15 carats, Sotheby’s explained. Similar blue diamonds have also fetched high prices, including the Blue Moon of Josephine, a cushion-shaped, 12.03-carat, fancy-vivid-blue, internally flawless diamond that sold for $48.5 million at Sotheby’s Geneva in 2015. Meanwhile, the Oppenheimer Blue, a step-cut, 14.62-carat, fancy-vivid-blue, VVS1-clarity stone, garnered $57.5 million at a Christie’s Geneva sale in 2016.

De Beers Cullinan Blue Diamond Could Bring $48M at Auction

De Beers Cullinan Blue Diamond

Sotheby’s will auction a stone described as “the largest vivid blue diamond ever to appear at auction” on April 27 in Hong Kong.

Sotheby’s estimates that it could bring $48 million.

Cullinan Blue Diamond

The 15.1 carat step-cut blue was cut from a rough stone discovered in April 2021. It is “the largest internally flawless step cut vivid blue diamond that the Gemological Institute of America (GIA) has ever graded,” according to a press statement.

“This diamond ranks as one of the best De Beers has ever seen,” said Bruce Cleaver, CEO of De Beers Group. “It is extremely rare and unique, and as the Home of Diamonds, De Beers is pleased to join together with Sotheby’s to bring this diamond to the world.”

Only five blue diamonds over 10 carats have ever come to auction, Sotheby’s notes. Until now, none has exceeded 15 carats.

“Blue diamonds of any kind are rare on the market, but this is the rarest of the rare; nothing of remotely similar calibre has appeared at auction in recent years,” says Patti Wong, chairwoman of Sotheby’s Asia. “Hundreds of millions of years in the making, this extraordinary blue diamond is surely one of nature’s finest creations.

The diamond comes from the Cullinan mine in South Africa.

20-Carat ‘Okavango Blue’ Diamond Goes on Display

The public can now feast their eyes on a big blue diamond thanks to New York’s American Museum of Natural History.  The museum opened an exhibition Tuesday showcasing the “Okavango Blue,” a 20.46-carat oval-cut fancy deep blue diamond on loan from Okavango Diamond Company, which is wholly owned by the government of Botswana. 

It has been given a VVS1 clarity grade from GIA.  The diamond came from Botswana’s Orapa mine and is the largest of its kind found in the country to date.  The Okavango Blue was named after Botswana’s Okavango Delta, a UNESCO World Heritage Site of global importance for biological conservation and diversity.  It’s the first time the diamond is on view to the public and sits at the center of a larger presentation about diamonds from Botswana, exploring industrial uses for diamonds and how Botswana runs its diamond industry as well as educating about the different characteristics of diamonds like size, shape, color, and quality.  Botswana is the second-largest producer of natural diamonds in the world, behind Russia.   Previous

Next “Our natural diamond resources are managed responsibly in a manner that puts the people of Botswana first,” said Okavango Diamond Company Managing Director Mmetla Masire. “There is a strong sense of local pride knowing that these diamonds are improving the lives of Batswana, with profits directly reinvested in education, infrastructure, and public health. “We are so pleased to share with the world the larger story of the diamond industry of Botswana. The Okavango Blue is not just an ordinary 3-billion-year-old polished carbon element, but rather a physical embodiment of the passing of time, a fragment of eternity. Our diamonds tell the rich history and unique journey of Botswana’s development.” The exhibition sits in the Melissa and Keith Meister Gallery in the museum’s new Allison and Roberto Mignone Halls of Gems and Minerals, which reopened in June after a major renovation.   The Okavango Blue and its corresponding Botswana diamonds exhibition will run for six months, AMNH confirmed.

Blue rough diamond fetches $40 million

                39.3 carat blue rough diamond

Petra Diamonds Ltd. sold a 39.3-carat blue gem for more than $40 million, making it one of the most expensive rough diamonds ever.

The small miner sold the exceptional Type IIb blue diamond to a joint venture between top producer De Beers and Diacore, a trading company owned by the billionaire Steinmetz family, it said Monday. The stone fetched just over $1 million per carat and is the most expensive gem Petra has ever sold.

Petra found the diamond at the Cullinan mine in South Africa in April. The mine, once owned by De Beers, is famous for both large and blue stones and was where world’s biggest diamond was found in 1905. Blue stones are among the most rare and valuable.

The sale is good news for Petra, which was forced to restructure its debt last year, when the Covid-19 crisis brought the industry to a standstill at a time when the company was already facing a mountain of debt and falling diamond prices. The shares, which were once worth more than $1.5 billion, closed up 1.1% on Monday.
