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

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

Diamond Prices Slide Amid Economic Uncertainty

 

Las Vegas… Diamond market sentiment received a boost from the Las Vegas shows, which demonstrated robust US demand. However, polished prices declined amid a weak global economic outlook and a rise in inventory levels.

The RapNet Diamond Index (RAPI™) for 1-carat diamonds slid 1.8% in June but increased 7.4% between the beginning of the year and July 1.

RapNet Diamond Index (RAPI™)
	June	1H 2022	Year on year July 1, 2021, to July 1 2022
RAPI 0.30 ct.	-1.0%	0.2%	-1.6%
RAPI 0.50 ct.	-1.6%	4.1%	5.0%
RAPI 1 ct.	-1.8%	7.4%	16.8%
RAPI 3 ct.	-0.8%	9.7%	22.2%

Trading in Las Vegas reflected jewelers’ strong liquidity after a profitable 2021. Activity slowed once the fairs ended and dealers headed for vacations at the beginning of July.

There were also renewed fears of a recession; the US economy shrank 1.6% in the first quarter, and the latest data showed inflation at 8.5% in May. Consumer confidence dropped 4.5 points in June to its lowest level since February 2021, according to The Conference Board.

Chinese demand was low as well following Covid-19 lockdowns in April and May. The lack of buyers meant local jewelers had sufficient inventory for the short term.

Polished inventory in the midstream grew in June. The number of diamonds listed on RapNet rose 4.3% during the month to 1.87 million as of July 1. The high volume came despite the Russian sanctions that limited Alrosa’s rough sales and took an estimated 30% of global production off the market. Russian rough shortages are expected to impact polished supply in the coming months; manufacturers have so far been working with goods from before Russia’s invasion of Ukraine.

Other miners are capitalizing on the new rough-market dynamic. De Beers’ June sales rose 36% year on year to $650 million after a price hike of 8% to 10% on smaller rough — a category Alrosa usually dominates.

We predict that traceable, ethical diamonds will sell at a premium to Russian diamonds as Alrosa goods reenter the market. While US jewelers are upbeat after the shows, there are political and economic headwinds that will likely disrupt the industry in the second half.

Study yields new insight in hunt for rare, valuable yellow diamonds

A new study by University of Alberta scientists could help guide the search for rare, high-value yellow diamonds in the Canadian North.

The researchers, led by PhD student Mei Yan Lai, examined the chemical makeup of stones recovered from the Chidliak and Ekati mines in Northern Canada to get a better understanding of how they formed.

“Without this research, we wouldn’t know that two separate formation events occurred, and that the second, more recent event is responsible for the yellow colour,” explained U of A diamond geologist Thomas Stachel.

“The more we know about the origin of these potentially high-value diamonds, the better results for diamond exploration and value creation in Northern Canada.”

Lai said they wanted to understand the origin of the yellow colour in the diamonds from the two deposits.

“Canadian yellow diamonds have never been studied spectroscopically in detail. Our results suggest that the cause is the preservation of unstable single nitrogen atoms preserved inside the diamonds,” explained Lai, who conducted this research as part of her master’s studies in the Diamond Exploration Research Training School under the supervision of Stachel.

The research team determined that some yellow diamonds contain colourless cores, meaning that the yellow outer layers crystallized on top of clearer centres. Lai determined that the yellow diamonds crystallized no more than 30,000 years before the kimberlite eruptions that brought them up to Earth’s surface.

“Our analysis shows that the colourless cores in these yellow diamonds are about one billion years older,” Lai said. “In fact, the carbon isotope compositions and nitrogen concentrations of the colourless cores and yellow outer layers are significantly different, suggesting that they formed in at least two distinct events and involved different diamond-forming fluids.”

The researchers said discovering a potential new source of yellow diamonds in the Canadian North is economically significant, as the previous main source of high-quality yellow diamonds, the Ellendale Mine in Western Australia, was recently shut down.

The discovery of colourless cores in some of the yellow diamonds may also be of interest to the jewelry trade, said Lai.

“Occasionally, rough yellow diamonds lose their vibrant yellow colour after being cut and polished—probably because this kind of diamond has a thin layer of yellow overgrowth on top of the geologically older colourless core,” she said.

The project is a collaboration with Dominion Diamond Mines and Peregrine Diamonds Ltd. Part of the analyses were done at the Gemological Institute of America.

The research is supported by a bursary through DERTS, funded by the Natural Sciences and Engineering Research Council of Canada’s Collaborative Research and Training Experience program.

The study, “Yellow Diamonds With Colourless Cores—Evidence for Episodic Diamond Growth Beneath Chidliak and the Ekati Mine, Canada,” was published in Mineralogy and Petrology.

Super-rich are investing in diamonds

Amid economic uncertainty, the super-rich are looking to ultra-rare precious gemstones as a ‘safe’ store for their wealth

Fine jewellery sales are seeming to weather the coronavirus crisis, thanks to lockdown proposals and demand for precious pieces to mark birthdays and anniversaries. Some jewellers report that people are spending more on gifts than usual, in lieu of ‘proper’ face-to-face celebrations.

And at the high end of the market, collectors are still investing in rare gemstones – sometimes seeing them as a safer store for their money than the volatile stock market or property.

Surat Diamond Manufacturing Shuts Down

The entire polishing industry in Surat has shut until March 31 after Indian authorities introduced tight restrictions to slow the spread of the coronavirus.

Activities stopped on Tuesday in line with a lockdown enforced by the Gujarat state government. The Bharat Diamond Bourse in Mumbai also closed from Friday until the end of the month following similar measures in Maharashtra state.

“In this panic situation, all are requested to stay at home, [stay] healthy, and spend time with family,” the Surat Diamond Association and the Gem & Jewellery Export Promotion Council (GJEPC) said in a joint letter to the Surat trade on Saturday. The organizations urged companies to shut their offices and manufacturing units in the city, the world’s largest center for polishing. Safe-deposit vaults will remain open for two hours each day, they noted.

The GJEPC said it had closed its head office in Mumbai until March 31, with all employees working from home.

Angola’s Rough-Diamond Revenue Rises in 2019

Revenue from Angola’s national diamond-trading company, Sodiam, rose 6% in 2019 as the company sold a higher volume of rough goods.

Proceeds for the year came to $1.3 billion from the sale of 9 million carats of rough diamonds, compared with 8.4 million carats in 2018, the government said in a Facebook post last week.  That offset a 10% drop in the average price to $137 per carat for the year. 

The increase came despite weakness in the rough-diamond market in 2019, with many miners, including De Beers and Alrosa, reporting a decrease in sales.

Angola implemented a new, more competitive diamond-trading policy that allows miners to offer 60% of their production to clients of their choice rather than selling through the state trading company.

In the fourth quarter, Sodiam sold 3 million carats of rough for $409 million, at an average price of $136 per carat.

De Beers Cuts Prices of Cheaper Rough

De Beers significantly reduced prices of lower-quality rough diamonds at this week’s sight in response to a slowdown in the Indian manufacturing sector, dealers reported.

Prices fell by high-single-digit percentages versus the previous sale, sightholders told Rapaport News Tuesday. The drops were for rough costing $100 per carat or less, including both small and large stones that produce polished with low color and clarity.

Those segments of the Indian manufacturing market have suffered most from the depreciation of the rupee and tighter bank lending to the trade in recent months. De Beers’ move also reflects the seasonal weakness due to the Diwali festival, when many companies close their factories for two weeks or longer.

“There were a few corrections to align prices with the markets,” a broker said. “It was nothing earth-shattering — what [De Beers] did was sensible given the time of year.” The miner scheduled the drop to ensure manufacturers returned from Diwali to a market with lower rough prices and therefore stronger profit margins, the broker added.
De Beers mostly maintained prices for higher-value rough as demand has been strong for polished that comes from those categories, a sightholder said. Even so, manufacturing profits are tight, he noted.

“Generally things are good, but it’s challenging to make a profit,” the sightholder added. “Because of rough prices this year, it’s been tough to make good money. It’s not about losing money, but there’s less money to be made.”
De Beers is scheduled to release the value of its ninth sales cycle next week. The miner declined to comment Tuesday.

Historic 910 carat, The Fifth Largest Diamond Recovered

Gem Diamonds has recovered a 910 carat rough diamond at its Letšeng mine in Lesotho, the fifth largest rough ever found.

The D colour  type IIa diamond is the largest to be unearthed at Letšeng, outranking the 603 carat Lesotho Promise recovered in 2006.

That stone was sold for $12.4 million, to Graff Diamonds, which owns a 15% stake in Gem Diamonds.

Last year, Graff bought the 1,109 carat Lesedi la Rona, the second largest rough diamond in history, for $53 million, or $47,790 per carat.

The discovery follows a recent revival of exceptionally large stones recovered at Letšeng, which is known for its high value production.
