De Beers Reduces Rough
Prices – Too Little?

De Beers apparently heard its clients and reduced the prices and quantities of rough diamonds it offered at the 4-8 May sight. The price cut was an average of 3%, concentrated mainly in the better qualities, while the cost of goods destined for the U.S. mass market remained relatively unchanged.

The May sight totalled about $450 million (£289 million), according to reports – way down from the $690 million (£443 million) of the March sight (there was no April sight) when clients walked away from an estimated 30-40% of their allocations because they were not profitable to cut and financing was expensive and difficult to come by. The refusal rate of the May sight, the first of the new 30-month term, was reportedly below 10%.

Diamond manufacturers had mixed views on the sight. Some believe the adjustment from De Beers was inadequate, noting that polished prices had declined by much more than 3% since the beginning of the year. The squeeze remains because polished prices have slipped much more than that since January. Others point out that lowering rough prices too much will compromise the value of existing rough inventories, further reducing sightholders’ available credit.

Alrosa will reportedly lower prices by a similar amount at its next sale in late May.

Diamond Treatments Keep Evolving

In 1999 GIA embarked on a crash research programme to detect natural diamonds that had been treated with the high pressure, high temperature (HPHT) process to improve their colour after they were introduced into the marketplace. On 12 May, GIA informed the trade that approximately 500 colourless to near-colourless diamonds submitted to its Ramat Gan grading laboratory had potentially been subjected to an undisclosed temporary treatment. The Institute notified the appropriate trade bodies, terminated client agreements with the several diamond firms that had submitted the stones in question and posted the report numbers of the potentially treated stones.

The World Federation of Diamond Bourses and other trade organisations can impose sanctions, including fines and expulsion from member diamond bourses, on dealers who intentionally attempt to sell treated or synthetic diamonds without disclosure.

More Diamond News

Blue Nile, the leading online diamond seller, reported that its first quarter diamond sales fell short of its goal, coming in at just 2.6% higher than the comparable period last year. The company had been reporting double-digit growth for much of its 15-year existence. A sharp decline in high ticket sales, especially those over $50,000 (£32,000), was responsible for the sales shortfall, the company said. Blue Nile reported that its engagement ring business − its mainstay − remained flat for the quarter, but that fashion jewellery and international sales had seen an upturn.

Auctions

More price records were exceeded again with Sotheby’s 12 May Geneva Magnificent Jewellery auction, where sales totalled more than $160.9 million (£103.3 million), the highest total ever achieved for a jewellery sale. The highlight was the 25.59 carat (ct.) “Sunrise Ruby” by Cartier, which drew a winning bid of $30.38 million (£19.5 million) – nearly $1.2 million (£770,000) per carat and nearly twice its pre-sale estimate. The Burmese ruby was unheated and commanded the highest price for a ruby ever achieved at auction.

Other notable sales at the 12 May Sotheby’s auction included:

  • An 8.72 ct. GIA-graded Fancy Vivid pink diamond believed to have belonged to Princess Mathilde, the niece of Napoleon Bonaparte, which sold for just over $16 million (£10 million); about $1.8 million (£1.15 million) per carat.
  • A natural pearl strand containing 78 pearls and a 4.39 ct. marquise shape diamond that went for just under $7 million (£4.5 million).
  • A 30.23 ct. Kashmir sapphire set by Cartier with 42.35 carats of diamonds, which drew a top bid of $6.1 million (£3.9 million).
The following day, also in Geneva, Christies’ sale realised $97 million (£62 million). The top lot was a 5.18 ct. GIA-graded Fancy Vivid pink diamond that sold for $10.7 million (£6.9 milion), or just over $2 million (£1.28 million) per carat. In addition, a 35.09 ct. cushion shape Kashmir sapphire sold for $7.35 million (£5.10 million), or $209,689 (£145,554) per carat, a record price for a gem from that region.

An Asian buyer purchased a 55.52 ct. GIA-graded D IF pear shape diamond for $9 million (£6.25 million), $162,000 (£112,000) per carat, while a single strand of 19th century natural pearl necklace sold to a dealer for $3.9 million (£2.7 million). The pearls ranged from 7.8 mm to 11 mm.

The highlight of Sotheby’s 21 April auction in New York the sale of a 100.2 ct. GIA-graded Type IIa D IF cut-cornered rectangular shape diamond that sold for $22 million/£15 million ($220,000/£158,000 per carat), right in the middle of its pre-sale estimate. This was a strong price in light of the pressures on top gems and other luxury items this year. In addition, a Type IIa 22.3 ct. marquise shape D IF diamond sold for $3.3 million/£2.3 million (about $150,000/£104,000 per carat).
