Spring 2016 Auction Update: Big Cheques – Mega Diamonds
May 23, 2016
Big diamonds – really big ones– dominated the news in May. Christie’s sold the 14.62 carat (ct.) Oppenheimer Blue for the highest price ever paid for any gemstone at auction: $57.5 million (£39.9 million). Also, mining company Lucara Diamond Corp. auctioned one of its major finds − a 812.77 ct. rough − for over $63 million (£43.7 million) and will sell its 1,109 ct. rough diamond named Lesedi La Rona at the end of next month.
Lucara auctioned the 812.7 ct. diamond on 8 May, with the winning bid going to a Dubai-based firm, Nemesis International. It was a record price for a rough diamond and unlike most diamond tenders, which are outright sales, it was for a 90% share in the stone, with the remainder held by Lucara.
The record price will certainly buoy expectations for Sotheby’s 29 June auction of Lucara’s 1,109 ct. stone – the second largest rough diamond ever found. That auction will be very public, conducted at Sotheby’s in London. Lucara had said it expected it to sell for more than $70 million (£48 million), a safe assumption after the smaller of the two fetched 90% of that price.
As if the Lesedi La Rona’s 1,109 carats (originally reported at 1,111 cts.) were not enough, the company announced that a 374 ct. rough found the day before had once been part of it. The company said it did not know if the piece broke off naturally or during the mining process.
Both Lucara diamonds came from the Kerowe Mine in Botswana; Lucara, based in Vancouver, is the full owner. Lucara, which found these two large diamonds last autumn, said that Kerowe had yielded eight stones larger than 100 carats during the first quarter of this year. The mine produces about 100,000 carats yearly with an average price of $649 (£450) per carat, according to the company’s annual report.
The Dubai dealer, Nemesis, purchased a 404 ct. rough mined in Angola by Lucara Diamond Co. earlier this year for a reported $16 million (£11 million). The diamond will be sold through De Grisogono, a Swiss-based luxury jeweller headed by Fawaz Gruosi.
Another group of significant diamonds – smaller but more colourful – are set to post price records in the final round of spring auctions.
Christie’s sold the GIA-graded 14.62 ct. Fancy Vivid blue Oppenheimer Blue diamond in Geneva on 18 May – the largest Fancy Vivid blue ever to come up for sale. Not to be outdone, Sotheby’s Geneva sold the 15.38 ct. GIA-graded Fancy Vivid pink Unique Pink diamond, the largest diamond of that grade ever to go under the hammer. The $31.6 million (£21.9 million) price came in at the lower end of the pre-sale estimate for the diamond mined in the old Kimberley deposits in South Africa. A 5.09 ct. GIA-graded Fancy Vivid green diamond will provide the finale for the 2016 spring season. The diamond, tracked from rough to rectangle cut and mounted in a ring surrounded by Fancy pink melee, is expected to sell for $16 to $20 million (£11 to £14 million).
De Beers’ chairman Philippe Mellier has noted that the company is “adopting a prudent mindset” for its rough diamond sales through the middle of the year. The company sold $660 million (£460 million) at its April sight (now called cycle) on top of about $1.2 billion (£830 million) at its two previous cycles in 2016. The company, however, announced its production will be down by about 10% – 26 to 28 million carats – for the year.
De Beers remained profitable through a difficult 2015, earning $571 million/£396 million (half of its 2014 profits, however), but its parent company Anglo American continues to struggle with high debts incurred by other projects that commenced when Chinese demand for resources seemed insatiable. Anglo is hoping to realise some $150 million (£104 million) from the sale of De Beer’s long-time Charterhouse Street headquarters.
Alrosa, the world’s largest producer by volume, estimated its yearly production will be 37 to 39 million carats, equal, to or slightly lower than 2015 levels. The company withheld 22 millions carats from the market last year as demand collapsed in the second half. The company stated that it wants to sell down the stocks it accumulated last year, while also selling new production, but keeping prices stable.
