India to Lead Demand for Natural Diamonds

India will lead demand for natural diamonds in 2024, says David Kellie, CEO of Natural Diamond Council (NDC), as US buyers increasingly switch to lab grown.

“The Indian market remains the strongest growth market in the world because of its strong financial position and changing demographics,” he told The Economic Times, in India.

“Indian women are now financially stronger, and they are driving the demand. The key economic indicators in the US are not yet favourable for a demand recovery in diamond purchase.”

Kellie (pictured) predicts a polarization between the natural and lab grown markets, with a price difference currently at 80 per cent to 90 per cent.

Natural diamonds will become increasingly rare, he said, with no new mines in prospect, and with miners digging deeper, and spending more, to reach remaining deposits.

De Beers Cuts Rough Prices by Average of 10% to 15%

De Beers reduced rough-diamond prices by an average of 10% to 15% at this week’s sight, aiming to stimulate sales and bring its rates more in line with the rest of the market, sources told Rapaport News.

The miner lowered prices by 5% to 10% for rough under 0.75 carats, with thinner or no reductions for the smallest items that produce melee, sightholders and other market insiders said Monday on condition of anonymity.

Rough weighing 0.75 to 2 carats saw reductions of approximately 10% to 15% on average, while prices of 2-carat and larger goods dropped about 15%, the sources added.

Select makeables — the 2- to 4-carat rough stones that produce SI2 to I2 diamonds — fell more sharply, with estimates ranging from 20% to 25%. This reflects the impact of lab-grown competition on mid-market US demand in the past year, sightholders explained. De Beers does not comment on pricing.

De Beers tends to sell less volume during a downturn and reduce prices only once the polished market has improved. The RapNet Diamond Index (RAPI™) for 1-carat diamonds slid 21% in 2023, the worst year on record for the category, but sightholders reported a moderate uptick in US demand since the holiday shopping season began, though Chinese orders remain weak.

The global market also stabilized as a result of India’s two-month voluntary freeze on rough imports, which ended December 15.

“[In the past, De Beers] didn’t want to change prices because they didn’t know [what the state of the] polished [market] was,” one of the sources commented. “They have an idea where polished is now, and have adjusted rough to polished.”

However, several sightholders said the drops did not go far enough, with De Beers’ prices still above those of outside tenders and auctions and also too high for many manufacturers to make a profit.

Even with the price reduction, the sources expected demand at the sight to be limited, with sales of around $300 million. The trading session, De Beers’ first of the year, began Monday and runs through Friday in Gaborone, Botswana.

De Beers approves $1 billion spending at Botswana mine

Global diamond giant De Beers said it will go ahead with a planned $1 billion investment to extend the life of its flagship Jwaneng mine in Botswana, even as last year’s downturn in gem demand persists.

The Anglo American (AAL.L) unit and the Botswana government, which jointly own Debswana Diamond Company, have approved the spending that will convert the Jwaneng pit into an underground operation.

Debswana said in 2018 it planned an investment to extend the lifespan of the mine by 11 years from 2024. De Beers said the spending is necessary as long-term supply of rough gems is expected to tighten.

Angola last year started mining at its new Luele project, the biggest in the country and one of the world’s largest by estimated resources, despite depressed diamond demand.

“The global supply of natural diamonds is falling, so moving forward with the Jwaneng underground project creates new value for investors,” De Beers CEO Al Cook said.

Demand for rough diamonds has been weak in recent months with India – cutter and polisher of 90% of the world’s rough diamonds – asking global miners to stop selling it gemstones to manage accumulated stocks.

“This investment is aligned with our strategy to prioritise investments in the highest quality projects,” Cook said.

De Beers last year agreed a new diamond sales pact, which will see the government’s share of diamonds from the Debswana joint venture gradually increase to 50% over the next decade.

Gem Diamonds and Lucara find first big stones of 2024

Africa-focused miners Gem Diamonds and Lucara Diamond have recovered big, high-quality Type IIa diamonds at their respective operations.

Gem Diamonds said on Thursday it had unearthed a 295-carat rough stone at its Letšeng mine in Lesotho, adding to a long list of diamonds over 100 carats found at the operation over the past two years.

The prolific mine is one of the world’s ten largest diamond operations by revenue. At 3,100 metres (10,000 feet) above sea level, Letšeng is also one of the world’s most elevated diamond mines.

Canada’s Lucara recovered a 166-carat rough in the Coarse X-Ray Transmission unit at its Karowe diamond mine in Botswana. The company said the precious stone was sourced from direct milling of ore from the South lobe of the mine.

Lucara’s latest find is the 328th diamond over 100 carats found at Karowe since it began operations in 2012. Chief executive William Lamb said  the recovery further supported the economic rationale for investing in the underground expansion project to extend the mine’s life to at least 2040.

The recoveries bring some positive news into a market affected by ongoing weak conditions, with prices for wholesale polished diamonds dropping 20% last year, which also dragged down rough diamond prices.

IGI Detects 6-Carat Lab-Grown Diamond With Fake Inscription

The International Gemological Institute’s laboratory in Tel Aviv recently detected a 6-carat lab-grown diamond that someone apparently was hoping to pass off as a natural stone.

The 6.01-carat, pear-shaped synthetic diamond was fraudulently inscribed with the Gemological Institute of America report number for a G-color natural diamond of the same size and shape, but with a few key differences, IGI said in a news release issued Tuesday.

First, the lab said, photoluminescence (PL) spectroscopy, which is now widely used by grading labs to separate natural diamonds from lab-grown stones and to identify diamond treatments, shows a wavelength peak of 737 nanometers in the diamond (see chart below).

This is an indicator that the diamond was grown in a factory using the chemical vapor deposition process.

Second, when examined under a microscope, IGI graders saw a carbon inclusion where the feather was indicated on the clarity plotting diagram in the GIA report.

They also noticed a cloud inclusion, resulting in IGI giving the lab-grown diamond a lower clarity grade than VVS1, the clarity grade of the natural diamond.

Lastly, there was a discrepancy between the depth of the diamond IGI examined and the depth noted on the GIA report.

“Everyone in our industry must be vigilant,” said IGI CEO Tehmasp Printer, who took over as head of the lab in October after Roland Lorie retired.

“As attempted fraud increases, the need for ongoing verification is a necessary step to protect consumers from purchasing misrepresented gems and jewelry.”

Sarine, GCAL Launch Surat Grading Lab Following Merger

Sarine Technologies and Gem Certification & Assurance Lab (GCAL) will open a new grading lab in Surat, India, following their business combination last year.

The new location will operate under the GCAL by Sarine banner, benefiting from Sarine’s technological and local expertise as well as GCAL’s grading brand, Sarine said Monday. The merged entity — formed when Sarine acquired 70% of GCAL for $5.65 million in May — already has a grading lab in New York.

“We are delighted to expand our activities into India, and we believe the timing is opportune,” said GCAL president Angelo Palmieri.

Certification and other grading services in both the New York and Surat locations will follow the merged group’s quality standards, Sarine said. The certificates will carry GCAL’s guarantee — a distinctive feature of its grading reports.

“We are dedicated to leading the way into a new era of diamond certification — one that relies increasingly on technology,” said Sarine CEO David Block. “This approach ensures the highest level of grading while introducing unprecedented efficiency. I have full confidence in our partnership and our ability together to take the certification market to new levels of quality and service.”

Bruce Cleaver Steps Down from De Beers Boards

Bruce Cleaver will leave his role as cochair of De Beers’ board of directors and will also relinquish his position on the board of the miner’s lab-grown diamond-manufacturing company, Element Six.

The move follows Cleaver’s exit as CEO in early 2023 after six years in the position. Cleaver’s appointment to the boards was to enable a smooth transition of leadership to his replacement, Al Cook, a De Beers spokesperson told Rapaport News.

Additionally, while on the board, “Bruce also supported the finalization of the commercial negotiations with the government of the Republic of Botswana,” the spokesperson said. “With the leadership transition complete, and with De Beers and Botswana having signed heads of terms for the new agreements, Bruce has delivered on those objectives, and so has stepped down from the board of directors.”

Cleaver will remain with De Beers in an advisory capacity, the spokesperson added. Duncan Wanblad, CEO of De Beers parent company Anglo American, will now be sole chair of the miner’s board of directors.
