China backs Russia in opposing bid to redefine conflict diamonds

China has joined Russia in opposing an effort to redefine conflict diamonds to include those sold by individual nations, as a rift between Western and pro-Russia nations jeopardizes the process for certifying rough diamonds as conflict-free.

Ukraine, Australia, Britain, Canada, the European Union, the United States and civil society groups were pushing to place Russia on the agenda at this week’s Kimberley Process (KP) meeting in Botswana and to broaden the KP’s definition, under which only gems funding rebel movements are “conflict diamonds”.

Russia, the world’s biggest producer of diamonds, has said the situation in Ukraine has “no implications” for the Kimberley Process.

China agrees that the Ukraine issue falls outside the scope of the KP, the country representative told the meeting, according to three sources. China joins Belarus, Central African Republic, Kyrgyzstan and Mali in backing Russia’s stance within the body, which seems unlikely to come to any agreement.

“It’s clear that this is posing really an existential crisis for the Kimberley Process,” said Hans Merket, a researcher at Belgian non-governmental organisation IPIS, who is a member of the civil society group.

“It has become impossible to even discuss the KP’s problems and shortcomings, let alone that there would be any room for convergence on how they can be addressed.”

China’s KP representatives did not respond to an emailed request for comment.

The KP certification scheme, designed to eliminate the trade in so-called “blood diamonds”, was set up in 2003 after devastating civil wars in Angola, Sierra Leone, and Liberia, which were largely financed by the illicit diamond trade.

The Kimberley Process Civil Society Coalition and some member states have been arguing to broaden that definition for years, but it is difficult to do as the KP makes decisions by consensus.

Jacob Thamage of Botswana, the current KP chair, said that more participants now believe reform is needed.

What is a ‘lab grown diamond’ ?

What is a ‘lab grown diamond’ ?

Laboratory grown diamond term is still a source of confusion for many diamond buyers and jewellers.

Natural Diamonds have been high coveted and sort after for thousands of years.

Diamonds have always been a status symbol for the elite and super wealthy, only becoming available to the general populations after large discoveries and marketing by the De Beers group.

The demand for mined diamonds has grown over the past century, At same time the source of new ground to mine has become ever increasingly hard to find or work.

This created the need for a scientific way to create alternatives. Enter Lab grown diamonds, or laboratory created diamonds.

Many Jewellers and most consumers are still confused about the process of creating a diamond, and how these stones actually differ from mined diamonds.

Laboratory grown diamonds are precisely the same in every way to mined diamonds but one. How the diamonds carbon bond grows under heat and pressure.

The growth structure of the carbon in natural mined diamond is haphazard and mixed with elements other than carbon. Nitrogen is the most common.

Lab grown are pure carbon for the most part, with distinctive growth structures visible under high magnification in gemological equipment available at the worlds notable laboratories.

How Can You Tell the Difference Between Lab Grown Diamonds?

Short answer is you can’t.

Lab grown diamonds are visually indistinguishable from natural diamonds, Not even and expert can tell the difference without gemological tasting equipment.

*DTC Diamond View at the DCLA Laboratory Sydney*

While some differences in old HPHT Lab diamonds can be identified under a special microscope, there’s nothing obvious about a lab grown diamond.

So how can a laboratory tell the difference?

Almost all natural diamonds contain traces of nitrogen, This is actually what gemologists use to screen out potential lab grown diamonds for further testing.

The actual gemological test requires state of the art gemological equipment. No counter top testers can prove the origin.

Are lab grown as durable as natural ?

The fact is lab grown diamonds are identical natural diamonds in strength, most of which have no flaws which could cause durability issues.

So as to the question Is a Lab Grown Diamond a Real Diamond ?

Answer is, Yes, lab grown diamonds are 100% as real as diamonds that have been mined from the earth.

Not only are they identical in every single way except origin, they have all the same optical properties as mined diamonds.

DCLA remains the only laboratory in Australia that guarantees, every diamond ever graded has been tested for origin and all known treatments.

De Beers rises small diamonds price amid shortage

De Beers, the world’s top diamond producer by value, has once again increased the price of its smaller stones as sanctions on Alrosa, its Russian rival, have worsened a global shortage caused by two years of covid-related shutdowns.

The Anglo American unit had hiked prices by about 8% at its first sale this year, with the sharpest increases of up to 20% affecting small-scale roughs, as demand reached pre-pandemic levels.

Prices for these diamonds, which usually end up clustered around the solitaire stone in a ring, have soared since early April, when Alrosa was targeted by US sanctions related to Russia’s invasion of Ukraine.

Diamonds are one of Russia’s top ten non-energy exports by value, with shipments in 2021 totalling over $4.5 billion, and its state-owned diamond producer is responsible for about a third of global supply.

Unlike Alrosa, De Beers doesn’t produce much of diamonds used in lower-end jewellery usually found a chain stores such as Costco or Walmart which is creating increasing shortages as Alrosa’s ability to supply the market remains uncertain.

People familiar with the matter told Bloomberg that De Beers applied a 5% to 7% price increase this week in Botswana, where the company holds 10 sales each year in events known as sights.

Around 60 handpicked customers known as sightholders are given a black and yellow box each time. These contain plastic bags filled with stones, with the number of boxes and quality of diamonds depending on what the buyer and De Beers had agreed to in an annual allocation.

De Beers rises small diamonds price amid shortage
Prices for small rough diamonds, the type that would end up clustered around the solitaire stone in a ring, are climbing.

*Prices for small rough diamonds are climbing.*

The miner increased the price of its rough diamonds throughout much of 2021 as it sought to recover from the first year of the pandemic when the industry came to a near halt.

The strategy, which applied to stones bigger than 1 carat, granted De Beers a steady recovery during the year, with prices gaining 23% in just over a year, parent company Anglo American said in a December presentation.

De Beers now only carries working inventory stocks and its mines are running at full tilt. There is little chance of material increases in supply before 2024, when a $2 billion underground expansion of its Venetia mine in South Africa is expected to be completed.

The diamond jewelry industry is going into the year with diamond supply at historically low levels, estimated by Bain & Company at 29 million carats in 2021. “Upstream inventories declined ~40%, driven by high demand and slow production recovery, and are near the minimal technical level,” the report stated.

US Demand, Uncertain Supply Buoy Diamond Prices

Diamond trading was stable in May despite concerns about inflation, rising interest rates and slumping stock markets. Polished prices initially declined but later steadied as dealers anticipated supply shortages resulting from Russian sanctions.

The RapNet Diamond Index (RAPI™) for 1-carat diamonds slid 0.5% in May but was 9.3% higher on June 1 than at the beginning of the year.

RapNet Diamond Index (RAPI™)
	May	Year to date Jan. 1 to June 1	Year on year June 1, 2020, to June 1 2021
RAPI 0.30 ct.	0.6%	1.3%	-0.1%
RAPI 0.50 ct.	-0.3%	5.8%	8.2%
RAPI 1 ct.	-0.5%	9.3%	22.1%
RAPI 3 ct.	-0.3%	10.6%	25.7%

US demand is supporting the market even as economic uncertainty sets in. Expectations are rising for the Las Vegas shows, which begin June 8. Dealers hope the positive sentiment will boost trading in the second half of the year. Chinese wholesalers remain cautious as activity resumes after the country’s Covid-19 lockdowns.

Inventory levels are high but have decreased in select categories. The number of diamonds on RapNet stood at 1.8 million as of June 1, up 43% from a year earlier. The quantity of 0.30-carat, D- to H-color, IF- to VS-clarity goods fell 14% in May; 0.50-carat diamonds in the same range declined 11%. Both categories were still significantly above last year’s levels.

While the sanctions on Russian goods have not yet caused notable polished scarcities, shortages are likely in the coming months. Rough supply has dropped since Alrosa canceled its March and April sales. Prices at rough auctions have increased — particularly in the small-diamond category, which Alrosa dominates. De Beers raised prices of small rough at its latest sight from June 6 to 10.

The market is splitting into two segments: Russian and non-Russian goods. Some big cutters are finding ways to buy Alrosa rough in order to serve centers that remain open to buying Russian-origin polished. These diamonds will likely sell at a discount to non-sanctioned ones.

US and European jewelers and brands may have difficulty filling their sourcing requirements in the coming months without Russian supply. This will lend further support to diamond prices.

Rio Tinto Launches Business for Argyle Pinks

*Diamonds from Rio Tinto’s Argyle Pink Diamond Tender.*

Rio Tinto has debuted a new strategy that will enable it to “protect the provenance” of its Argyle pink diamonds, including a certification service and a concierge trading platform.

“This is the start of a new chapter for Argyle pink diamonds, to ensure they maintain their value and investment potential as a finite, unrepeatable natural resource and achieve the status of outstanding heritage diamonds,” Rio Tinto Minerals CEO Sinead Kaufman said last week.

The venture will also play host to a new Beyond Rare tender platform for special sales events, as well as several strategic collections and collaborations involving existing inventory and the secondary market.

One such venture, the Icon Partner program, will give jewelers licensing rights to use the Argyle Pink Diamonds brand for jewelry they create with any remaining inventory they previously purchased from the Argyle mine. The first two retailers Rio Tinto has authorized are John Calleija, the owner of Australian luxury-jewelry house Calleija, and Singapore-based Glajz THG, owned by John Glajz.

“The secondary market for Argyle pink diamonds comprises almost 40 years of rare, polished pink diamonds, together with heirloom pieces of jewelry, collectibles and objects,” the miner noted. “This market requires careful management to preserve the precious provenance of Argyle pink diamonds and continue the legacy of careful custody that underscores its rarity.

Gem Diamonds unearths 125-carat diamond in Lesotho

Africa-focused Gem Diamonds has found a 125 carat rough stone at its Letšeng mine in Lesotho, the miner’s second rock over 100 carats mined this year.

The company, known for the recovery of large, high quality stones in 2020, has seen output of high quality diamonds surpassing the 100 carat mark become less frequent over the past year.

In 2021, Gem Diamonds found only six of such diamonds at Letšeng, compared to the 16 it discovered in 2020.

The find comes as prices for small diamonds have jumped about 20% since the start of March, as cutters, polishers and traders struggle to source stones outside Russia.

State owned Russian miner Alrosa, the world’s top diamond producer by output, was hit with US sanctions following Moscow’s invasion of Ukraine.

Higher prices for lower end stones are good news for miners, but not a game changer, experts say. While every mine is different, a general rule is that 20% of production the best stones account for about 80% of profits.

Since acquiring Letšeng in 2006, the company has found more than 60 white gem quality diamonds over 100 carats each, with 16 of them recovered last year. At an average elevation of 3,100 metres (10,000 feet) above sea level, Letšeng is also one of the world’s highest diamond mines.

DRC Embarks on Mine-to-Market Program for Artisanal Diamond Miners

The first steps towards setting up a traceability program have been taken in Democratic Republic Congo (DRC), which dominates the world’s supply of diamonds from artisanal and small-scale mining (ASM).

A pilot project involving Antwerp World Diamond Centre (AWDC), the DRC mining ministry and tech company Everledger aims to establish a fully transparent value chain in a country which has a diamond sector vulnerable to human rights violations, poor working conditions, corruption and opaque or illicit trade.
The project, called OrigemA, is initially being funded by the AWDC and will focus on transparency, sustainability and fair trade.
The DRC is the largest producer of artisanal mined diamonds in the world, accounting for nearly 70 per cent of global ASM production, which in turn constitutes an estimated 15 to 20% of the total diamond production in the world.
DRC’s mining minister Antoinette N’Samba Kalambayi said stakeholders “will work with the other partners to create a legal and fiscal framework that allows efficient formalization, combatting corruption, eradicating logistical hurdles, and increasing transparency in financial and fiscal flows.”
Karen Rentmeesters, AWDC’s head of industry relations, said: “This bottom-up, collaborative approach ensures that we create a model that considers the realities of artisanal, small-scale mining in remote regions and that the resulting blueprint can be scaled up and replicated in the field.”

Gem Diamonds finds 129-carat diamond in Lesotho

Africa focused Gem Diamonds has found a 129 carat rough stone at its Letšeng mine in Lesotho, the miner’s first one over 100 carats mined this year.

The high quality white diamond was recovered at the site over the weekend, Gem Diamonds said. The company, known for the recovery of large, high quality stones in 2020, has seen output of those diamonds become less frequent over the past year.

In 2021, Gem Diamonds found only six diamonds over 100 carats at Letšeng. This compares to 16 rocks of more than 100 carats discovered in 2020.

The find comes as prices for small diamonds have jumped about 20% since the start of March, as cutters, polishers and traders struggle to source stones outside Russia.

Lucapa says 204 carat diamond recovered at Mothae mine in Lesotho

Lucapa Diamond Company yesterday announced the recovery of a 204 carat diamond from the Mothae mine in Lesotho.

According to the company’s statement, the 204 carat white stone is the eighth +100 carat diamond and third +200 carat to be recovered from the Mothae mine since commercial mining commenced in January 2019, underlining its unique large stone nature.

Lucapa Diamond Company is an ASX listed diamond miner and explorer with assets in Africa and Australia. It has interests in two producing diamond mines in Angola (Lulo) and Lesotho (Mothae).

“The large, high-value diamonds produced from these two niche African diamond mines attract some of the highest prices per carat for rough diamonds globally,” the company said.

The Lulo mine has been in commercial production since 2015, while the Mothae mine commenced commercial production in 2019.

Botswana sees Russian diamond ban opening door to synthetic gems

*Mirny, Sakha Republic, Russian Rough Dimaonds*

Botswana, Africa’s top diamond producer, sees a prolonged ban on Russian diamonds opening the way for synthetic gems to expand market share, the country’s minister told a mining conference on Monday.

The United States, the world’s largest market for natural diamonds, imposed sanctions on Russia’s state-controlled Alrosa in April, aiming to cut off a source of revenue for Moscow after its February invasion of Ukraine.

Alrosa, the world’s largest producer of rough diamonds, accounted for about 30% of global output in 2021.

Botswana’s Minister of Minerals and Energy Lefoko Moagi said the ban on Russia diamonds might push prices up to the benefit of rival producers but he also said the gap would be hard to fill.

“We see the 30% gap that will be left by the ban being plugged by something else that is not natural. And for us that will be a challenge,” he said.

Jacob Thamage, head of Botswana’s Diamond Hub, said uncertainty over the Ukraine conflict makes it difficult for Botswana and other natural diamond miners to fill the supply gap as ramping up operations requires significant investment.

“You don’t want to invest a lot of money to up-scale and then the war ends the next day,” Thamage said. “We also see the higher prices pushing consumers to substitutes such as the synthetics and this can cause problems for us if we cede the market to unnatural stones.”

Sales at Debswana, a joint venture between Anglo American unit De Beers and Botswana’s government, accounts for almost all of Botswana diamonds exports. These stood at $3.466 billion in 2021 compared with $2.120 billion in 2020.

Thamage also fears that consumers might start to shun natural diamonds due to traceability issues.

“There is an increased fear that buyers of diamonds will begin to treat all natural diamonds as conflict diamonds and therefore shift to unnatural diamonds,” he said.
