Botswana’s diamond sector is facing a combination of weak natural-diamond demand, pressure from excess industry inventory, competition in price-sensitive categories, lower rough-diamond revenue and uncertainty surrounding the future ownership of De Beers.
The issue reaches far beyond mining. Diamonds have historically represented approximately 70% of Botswana’s exports and around one-third of government revenue, making changes in production and sales important to public finances, foreign-exchange earnings, employment and national economic growth.[1]
Quick answer :
Botswana’s diamond industry is under pressure because demand for natural diamonds remains weak while producers and cutting centres continue to manage excess inventory. Laboratory-grown diamonds are also competing strongly in lower-value, price-sensitive categories. Botswana’s exposure is unusually high because diamonds support a large share of its exports and government income.
Botswana Diamond Sector: Key Facts at a Glance
Botswana is one of the world’s most important natural rough-diamond producers. Its diamond relationship with De Beers operates primarily through Debswana Diamond Company, a 50:50 joint venture between the Government of Botswana and De Beers.[2]
Debswana operates major assets including the Jwaneng and Orapa mines. Botswana also owns a 15% interest in De Beers itself, giving the country exposure both to local mining operations and to the wider De Beers business.

The comparison between production and revenue is important. Botswana’s production increased in the second quarter of 2026, but De Beers’ consolidated rough-diamond sales revenue remained substantially below the comparable 2025 quarter.[3]
Key distinction: Higher mine output does not automatically mean stronger demand, higher prices or improved profitability. Production, sales volume, realised price, revenue and inventory should be analysed separately.
Why Has Natural-Diamond Demand Weakened?
Botswana’s difficulties are part of a broader natural-diamond market downturn rather than the result of one isolated event.
Weaker demand in China
Demand for natural-diamond jewellery in China has weakened, reducing one of the industry’s important sources of growth. The IMF has identified reduced natural-diamond demand, including weaker Chinese demand, as an important pressure on Botswana’s economy.[4]
Excess rough and polished inventory
When consumer demand falls more quickly than producers, cutters and retailers reduce supply, inventory accumulates across the value chain. High inventory can discourage new rough-diamond purchases while existing polished stones are sold through.
Producers may respond by reducing output, offering customers greater purchasing flexibility, extending maintenance periods or processing different ore grades. These actions are designed to align supply more closely with demand, but adjustments can take time.
Competition from other luxury spending
Natural diamonds compete not only with laboratory-grown diamonds but also with travel, technology, gold jewellery and other discretionary purchases. Changes in consumer confidence, interest rates and economic expectations can therefore influence diamond demand.
Laboratory-grown competition
Laboratory-grown diamonds offer diamond material at substantially different pricing from many comparable natural diamonds. Current De Beers reporting indicates that they continue to affect demand particularly for lower-value natural stones and other price-sensitive categories.[3]
Laboratory-grown diamonds are an important factor, but they should not be treated as the only cause of Botswana’s downturn. Weak Chinese demand, excess inventories, luxury-spending changes, macroeconomic uncertainty and geopolitical disruption also play roles.
How Is the Diamond Downturn Affecting Botswana’s Economy?
Botswana’s dependence on diamonds means that a prolonged market downturn can affect economic activity well beyond the mines.
The IMF reported that Botswana’s economy contracted by 3% in 2024, with mining output declining by 24% and diamond trading declining by 34%. Its 2025 review said economic activity was expected to continue contracting as diamond production and non-mineral activity weakened.[4]
The IMF also highlighted:
- Tighter banking-sector liquidity connected with the diamond contraction
- A fiscal deficit expected to exceed 8% of GDP in 2025
- Pressure on Botswana’s current-account balance
- The risk of declining international reserves
- A greater need for economic and revenue diversification
In March 2026, S&P Global Ratings lowered Botswana’s long-term sovereign rating from BBB to BBB- and retained a negative outlook. The agency cited structural weakness in the global diamond market and projected continued fiscal pressure unless demand recovered strongly or policy adjustments were made.[1]
Why forecasts can differ
Economic forecasts are estimates produced at a particular date and may use different information, assumptions and revised national data. Readers should therefore check:
- The date of the forecast
- Whether the figure is an estimate or confirmed outcome
- The institution’s assumptions about diamond demand
- Expected government spending and borrowing
- Projected production and rough-diamond prices
Forecasts should not be presented as guaranteed outcomes.
Debswana Production, Sales and Operational Adjustments
Debswana’s production decisions influence Botswana’s export earnings and De Beers’ available rough-diamond supply. However, production must be viewed alongside market demand.
Anglo American’s Q2 2026 production report recorded approximately 5.5 million carats of Botswana production during the quarter, compared with approximately 2.7 million carats in Q2 2025. The increase reflected the effect of extended maintenance at Orapa during the comparison period and planned mining of higher-grade ore at Jwaneng.[3]
The report also warned that planned maintenance at Orapa and Jwaneng during the second half of 2026 was expected to reduce production from the Q2 run rate.
Sales remained challenging
De Beers described rough-diamond trading conditions as challenging during the first half of 2026. Its Q2 rough-diamond sales totalled approximately 7.1 million carats, or 6 million carats on a consolidated basis, generating approximately $665 million in consolidated revenue.
In Q2 2025, approximately 7.6 million carats were sold, or 6.8 million on a consolidated basis, generating roughly $1.2 billion. The comparison demonstrates that broadly similar sales volume can produce very different revenue when the product mix and realised prices change.[3]
Why ore grade matters
Carat production alone does not describe the full value of mine output. Revenue can vary according to:
- Average size of recovered stones
- Colour and clarity distribution
- Shape and model characteristics
- Share of higher- and lower-value goods
- Current demand for each category
- Timing and composition of sales
A mine can recover more carats without producing an equivalent increase in revenue.
What Changed in the New Botswana–De Beers Agreement?
On 25 February 2025, Botswana and De Beers signed formal agreements covering:
- A new 10-year sales agreement
- The possibility of extending that sales agreement by another five years
- A 25-year extension of Debswana’s mining licences
- Mining-licence continuity from 2029 through 2054
The agreements cover the long-term sale of Debswana’s rough-diamond production and provide operating certainty for the Jwaneng and Orapa mines.[2]
Why the agreement matters
The agreement gives both parties a longer planning horizon for:
- Mine-life investment
- Plant maintenance and expansion
- Local sales and beneficiation
- Cutting and polishing activity
- Skills development
- Government revenue planning
It also highlights a central tension. Botswana secured a stronger long-term commercial framework at a time when the natural-diamond market was experiencing unusually weak demand.
Why Does the Proposed De Beers Sale Matter to Botswana?
Botswana owns 15% of De Beers. Anglo American placed its controlling interest in De Beers up for sale as part of a wider corporate restructuring.
On 17 July 2026, Botswana said Anglo American had selected the Global Diamond Consortium as its preferred bidder. Botswana was still evaluating whether to:
- Exercise its right of first refusal independently
- Join the preferred bidder as a partner
- Work with another third party
- Use a different ownership structure
As of 27 July 2026, no final ownership transaction had been announced. Botswana’s government said it was working with financial advisers and expected the transaction process to conclude in the final quarter of 2026, subject to conditions and government approval.[5]
Status note: The preferred bidder is not yet the confirmed final owner. This section should be reviewed again immediately before publication because the transaction is still in progress.
Potential opportunities
A larger Botswana role in De Beers could provide greater strategic influence over:
- Rough-diamond sales
- Marketing and category development
- Beneficiation and local value addition
- Producer-country collaboration
- Long-term investment decisions
Potential risks
A larger ownership position could also expose Botswana more directly to:
- Natural-diamond price volatility
- Turnaround and restructuring costs
- Funding requirements
- Inventory and retail-market risk
- Long-term competition from laboratory-grown diamonds
The quality of the final ownership structure, funding plan and operating expertise may therefore be as important as the percentage Botswana ultimately owns.
How Are Laboratory-Grown Diamonds Affecting Botswana?
Laboratory-grown diamonds are real diamond material created through controlled CVD or HPHT processes rather than geological formation. Their production can be expanded in response to manufacturing capacity, which gives them different scarcity and pricing dynamics from natural diamonds.
The strongest competitive effect is currently visible in lower-value and price-sensitive natural-diamond categories. Buyers comparing engagement rings may choose a laboratory-grown centre stone to obtain a larger visible size or allocate more of their budget to the setting.
That does not mean laboratory-grown and natural diamonds serve exactly the same buyer intent.

Moissanite is not a laboratory-grown diamond. It is a separate silicon-carbide gemstone and should be disclosed by its own name.

Are Botswana Diamonds Traceable and Conflict-Free?
Botswana participates in the Kimberley Process Certification Scheme, which regulates international trade in rough diamonds between participating countries.
The Kimberley Process defines conflict diamonds narrowly as rough diamonds used by rebel movements or their allies to finance armed conflict aimed at undermining legitimate governments.[6]
Kimberley Process compliance is important, but it should not be treated as proof of every ethical, labour, environmental or community condition associated with a finished piece of jewellery.
What Kimberley Process compliance covers
- International shipments of rough diamonds
- Trade between participating countries
- Certification intended to prevent narrowly defined conflict diamonds entering legitimate trade
What buyers may still need to ask
- Can the seller identify the diamond’s country, producer or mine?
- What chain-of-custody records are available?
- Where was the diamond cut and polished?
- What labour and environmental standards were applied?
- Does the claim cover the rough diamond, polished diamond or complete jewellery item?
- Are the accompanying documents independently verifiable?
A “conflict-free” description should be accompanied by an explanation of the standard or evidence being used. It should not function as an undefined promise covering every possible social and environmental issue.
For more detail, read Rosec Jewels’ guide to what conflict-free diamonds really mean.
Will Botswana’s Diamond Challenges Raise Jewellery Prices?
There is no simple one-to-one relationship between Botswana’s mine output and the retail price of a diamond ring.
Botswana is a major producer, so sustained production reductions can influence global rough supply. However, the final price of a polished diamond or finished piece also depends on:
- Existing rough and polished inventory
- Diamond size, colour, clarity and shape
- Cutting and polishing costs
- Exchange rates
- Retail demand
- Producer pricing decisions
- Retailer margins
- Laboratory-grown competition
- Metal prices and jewellery manufacturing
In a weak-demand environment, reduced production can be an attempt to prevent further inventory accumulation rather than a signal that immediate retail shortages are expected.
Why different natural diamonds may behave differently
Market conditions can vary by:
- Size category
- Quality range
- Fancy or colourless material
- High- or low-value rough
- Shape demand
- Origin and traceability documentation
Pressure from laboratory-grown diamonds may be stronger in some lower-value categories than among rare, exceptional or highly documented natural stones.
What Should Buyers Check Before Choosing a Diamond?
Botswana’s industry challenges do not change the core steps of buying responsibly. Buyers should compare the individual diamond, its documentation and the retailer’s policies.
- Confirm the material: Is it a natural diamond, laboratory-grown diamond, moissanite or another simulant?
- Check origin wording: Laboratory-grown origin should be displayed clearly and close to the diamond description.
- Identify the report issuer: Establish which laboratory or organisation issued the document.
- Verify the report number: Use the issuer’s official report-check service where available.
- Compare the 4Cs: Review cut, colour, clarity and carat weight together.
- Check dimensions: Carat is weight; millimetre dimensions indicate visible face-up size.
- Review treatments: Ask whether any colour or clarity treatment was detected.
- Ask about provenance: Determine what the retailer can document about origin and chain of custody.
- Read the policies: Confirm return, exchange, resizing, warranty and custom-order terms.
- Separate price from investment: Neither natural nor laboratory-grown diamonds guarantee profitable resale.
The FTC advises businesses to identify laboratory-grown diamonds conspicuously and to avoid broad environmental claims that cannot be substantiated. General descriptions such as “green,” “eco-friendly” or “sustainable” should therefore be supported by specific evidence.[7]

Botswana Diamond Outlook for 2026 and Beyond
Botswana’s near-term outlook depends on factors that the country can influence and others that it cannot control.
Factors Botswana can influence
- Public spending and fiscal adjustment
- Economic diversification
- Local cutting, polishing and jewellery manufacturing
- Skills development
- Debswana operating efficiency
- The structure of any increased De Beers ownership
- Traceability and provenance systems
- Investment in non-diamond sectors
External factors
- Natural-diamond demand in the United States and China
- Global luxury spending
- Laboratory-grown diamond prices and adoption
- Geopolitical and trade disruption
- Interest rates and consumer confidence
- Industry inventory levels
The February 2025 agreement provides long-term mining and sales certainty, but it cannot by itself restore global demand. Similarly, higher production in one quarter should not be interpreted as a complete recovery when realised prices and sales revenue remain under pressure.
The unresolved De Beers sale adds another strategic decision. Greater ownership could increase Botswana’s influence over the natural-diamond value chain, but it could also increase the country’s financial exposure to an industry undergoing structural change.
The most durable response is therefore likely to combine careful management of existing diamond assets with wider economic diversification.
Frequently Asked Questions
Why is Botswana’s diamond industry under pressure?
Demand for natural diamonds has remained weak while the industry has worked through excess rough and polished inventory. Weak Chinese demand, economic uncertainty, competition from other luxury purchases and laboratory-grown diamonds in price-sensitive categories have all contributed. Botswana is particularly exposed because diamonds provide a large share of its export earnings and government revenue.
How important are diamonds to Botswana’s economy?
Diamonds have historically represented around 70% of Botswana’s exports and approximately one-third of government revenue. This means lower diamond production or sales can affect foreign-exchange earnings, public finances, economic growth and liquidity across the wider economy.
What is Debswana?
Debswana Diamond Company is a 50:50 joint venture between the Government of Botswana and De Beers. It operates major Botswana diamond mines including Jwaneng and Orapa and is central to the country’s diamond production and revenue.
Is Botswana reducing diamond production?
Production has been adjusted according to mine plans, maintenance and market demand. Botswana produced approximately 5.5 million carats in Q2 2026, but planned maintenance at Orapa and Jwaneng was expected to reduce output from that quarterly rate during the second half of the year.
Did Botswana’s diamond sector recover in Q2 2026?
Production increased strongly compared with Q2 2025, but this did not establish a full market recovery. The comparison was influenced by maintenance in the earlier period and planned processing of higher-grade ore. De Beers’ Q2 2026 consolidated rough-diamond sales revenue remained considerably below the comparable 2025 quarter.
What did the new Botswana–De Beers agreement change?
The parties signed a new 10-year sales agreement, with a possible five-year extension, and extended Debswana’s mining licences for 25 years from 2029 through 2054. The arrangement provides long-term operating and sales certainty for major Botswana mines.
Is Botswana buying De Beers?
No final acquisition had been announced as of 27 July 2026. Botswana already owns 15% of De Beers and was evaluating whether to exercise its right of first refusal, partner with Anglo American’s preferred bidder or use another structure.
Are laboratory-grown diamonds the main cause of Botswana’s downturn?
They are one important factor, especially for lower-value natural diamonds and price-sensitive engagement-ring purchases. However, Botswana’s challenges also reflect weak Chinese demand, excess inventory, global economic uncertainty, changing luxury spending and lower realised prices.
Will Botswana’s difficulties make natural diamonds more expensive?
Not automatically. Production changes can affect rough supply, but retail prices also depend on existing inventory, diamond category, cutting costs, exchange rates, retailer margins and consumer demand. Different sizes and qualities may respond differently.
Are Botswana diamonds conflict-free?
Botswana participates in the Kimberley Process, which is designed to prevent narrowly defined conflict diamonds from entering international rough-diamond trade. However, Kimberley Process compliance does not by itself verify every labour, environmental, community or human-rights condition associated with a finished piece of jewellery.
Does conflict-free mean fully traceable?
No. “Conflict-free” and “traceable” are not identical. Traceability normally requires records connecting the polished diamond to a country, producer, mine or controlled supply chain. Buyers should ask what documentation supports the seller’s specific claim.
What should buyers compare between natural and laboratory-grown diamonds?
Compare origin, cut, colour, clarity, carat weight, dimensions, treatments, report type, setting quality, price, retailer policies and realistic resale expectations. The better choice depends on whether the buyer prioritises natural rarity, purchase price, visible size, provenance or another factor.
