Quick answer: Lab-grown diamonds are placing significant pressure on parts of the natural-diamond industry, especially commercial engagement-ring categories where buyers can obtain a larger laboratory-grown stone for a lower upfront price.
However, lab-grown competition is not the natural-diamond sector’s only challenge. Weaker Chinese demand, excess inventory, economic uncertainty, tariffs, changing bridal behaviour and lower luxury spending have also affected natural-diamond prices and production.
The market is not simply replacing one diamond with another. Lab-grown diamonds are gaining unit demand through affordability, while natural diamonds retain higher average prices and appeal among buyers prioritising geological rarity, provenance and natural origin.
The diamond market has changed more rapidly than many retailers, producers and buyers expected.
Laboratory-grown diamonds have moved from a specialist alternative to a significant part of bridal and fine jewellery. At the same time, major natural-diamond producers have reduced output, restructured operations and invested in new marketing intended to distinguish natural diamonds from their laboratory-grown counterparts.
For consumers, the result is greater choice. For the industry, it creates difficult questions about pricing, inventory, scarcity, value and how each diamond category should be positioned.
This article examines how lab-grown diamonds are affecting the natural-diamond industry, which parts of the market face the greatest pressure and what the changes mean for someone choosing a diamond in 2026.

What the Original 2025 Report Said
The original headline—“The natural diamond industry is getting rocked. You can thank the lab-grown variety for that”—came from a CBC News Business article published on July 26, 2025.
The report examined declining natural-diamond prices, the growing popularity of laboratory-grown diamonds and the difficulties facing diamond-mining operations, including parts of Canada’s mining industry.
Its central argument was directionally important: lower-priced lab-grown diamonds had become a serious competitive force, especially in engagement rings.
However, attributing the entire natural-diamond downturn to lab-grown competition oversimplifies a market shaped by several interconnected forces. Newer evidence available through July 2026 provides a more complete picture.
Is the Natural-Diamond Industry Really Under Pressure?
Yes. Several current indicators show that the natural-diamond supply chain remains under substantial pressure.
On July 13, 2026, the Financial Times reported that De Beers would suspend production at its Venetia mine in South Africa for two years. The mine employs approximately 3,500 people and accounts for about 10% of De Beers’ production.
The report also stated that a widely followed rough-diamond price index was approximately 50% below its 2022 peak. De Beers had already reduced annual overhead costs and paused another expansion project as it responded to difficult market conditions.
Anglo American, De Beers’ majority owner, had previously written down the diamond company’s value and continued working toward a sale of the business.
These developments demonstrate that the sector’s problems are significant. They do not prove that natural diamonds have become unwanted or worthless. The pressure differs by country, diamond quality, price level and stage of the supply chain.
Five Forces Reshaping the Natural-Diamond Market
Competition From Lower-Priced Lab-Grown Diamonds
- Carat weight
- Visible size
- Colour and clarity labels
- Setting style
- Total ring price
Weaker Demand in China
Excess Inventory
- Reduce new purchases
- Discount older goods
- Delay production
- Hold more capital in unsold inventory
- Request longer payment terms
- Reduce mining or manufacturing output
Economic and Trade Pressure
Changing Bridal and Luxury Priorities
- A larger centre stone
- A detailed custom setting
- Lower upfront cost
- Transparent origin disclosure
- Personal design and symbolism
- Geological rarity
- Natural formation history
- Provenance
- Collectability
- Traditional natural-diamond symbolism
Lab-grown diamonds give buyers access to diamond’s familiar hardness and optical characteristics at a substantially lower upfront price than many natural diamonds with broadly comparable specifications.
This price difference is particularly influential in commercial bridal categories, where buyers often compare:
A BriteCo report covered by Rapaport found that lab-grown diamonds were present in approximately 42% of the diamond jewellery in its 2025 dataset, including 48% of engagement rings.
The report also found that the average lab-grown engagement-ring centre stone had become considerably larger over time. These figures come from one jewellery insurer’s data and should not be treated as a complete census of every US purchase, but they demonstrate that lab-grown bridal adoption is no longer marginal.
Reduced demand in China has been a major challenge for natural-diamond producers.
De Beers reported that Chinese demand remained muted during 2025, even as higher-end natural-diamond categories performed more strongly in the United States.
Factors influencing Chinese demand include economic uncertainty, weaker consumer confidence, changing marriage patterns and increased interest in gold as both jewellery and a store of value.
This matters because a decline in one major market can increase inventory throughout the international diamond supply chain.
Natural diamonds move through a long supply chain that may include miners, rough traders, cutters, polishers, wholesalers, manufacturers and retailers.
When consumer demand slows, inventory can accumulate at several stages. Businesses may then:
Large inventories can continue pressuring the market even when consumer demand begins to improve, because existing goods must still move through the system.
Diamond jewellery is a discretionary purchase. Interest rates, inflation, employment confidence, tariffs and wider luxury spending can all affect demand.
International trade rules also matter because rough diamonds may be mined in one country, cut and polished in another, set into jewellery elsewhere and sold into a different consumer market.
Additional costs or delays at any stage can affect retailer margins and final prices.
Many buyers now define value more broadly than previous generations.
Some prioritise:
Others continue to value:
The market increasingly serves both groups rather than relying on one universal definition of luxury.

The table shows why market share, unit sales, revenue and price must be evaluated separately.
Lab-grown diamonds can gain unit share while their price per stone falls. Natural-diamond units can decline while remaining buyers spend more on higher-value pieces.
Which Natural Diamonds Face the Greatest Pressure?
Pressure is not distributed evenly throughout the natural-diamond market.
Commercial-quality natural diamonds commonly used in mainstream bridal jewellery face the most direct comparison with lab-grown alternatives. Buyers can easily compare two similarly shaped diamonds and see a large difference in carat size or price.
Natural diamonds may face stronger competition when they are:
- Common round or oval bridal sizes
- Near-colourless commercial grades
- Sold primarily according to the 4Cs
- Offered without distinctive provenance
- Part of generic or easily replicated designs
The price difference becomes harder to justify when the natural diamond is presented only as a specification sheet rather than as a scarce product with documented origin and a distinctive finished design.
Why Premium Natural Diamonds Can Behave Differently
Lab-grown competition does not affect every natural diamond in the same way.
Unusual, rare or highly documented natural diamonds may serve buyers who are not primarily seeking the largest possible carat weight for their budget.
Potential differentiators include:
- Fancy natural colour
- Exceptional size
- Rare cut or shape
- Documented country of origin
- Historic provenance
- Recognised designer or brand
- Distinctive inclusions or natural character
- Exceptional craftsmanship
De Beers’ 2026 US consumer research reported higher average spending on natural-diamond jewellery in 2025. Because the research was commissioned by a natural-diamond producer, it should be interpreted as industry-sponsored evidence rather than an independent market verdict.
The findings nevertheless align with a broader pattern: some consumers are purchasing fewer natural-diamond items but spending more when they do buy.
How the Natural-Diamond Industry Is Responding
Reducing production and controlling supply
Mining companies have reduced production, paused expansion and reviewed projects that may not remain profitable at current prices.
Supply discipline can help prevent additional rough inventory from entering an already pressured market, although production changes take time to affect polished retail supply.
Investing in natural-diamond marketing
The natural-diamond sector is increasing efforts to explain geological rarity, provenance, cultural meaning and the economic contribution of diamond-producing regions.
The Natural Diamond Council has explored a hallmark or identification initiative intended to help consumers distinguish natural diamonds from laboratory-grown stones. Industry participants have also launched campaigns focusing on natural colour, individuality and emotional legacy.
Improving provenance and traceability
Natural-diamond companies increasingly recognise that origin claims must be supported with documentation.
Traceability programmes may help buyers understand:
- Where a diamond originated
- How it moved through the supply chain
- Which businesses handled it
- Whether specific sourcing standards were applied
Traceability does not automatically prove that every environmental or social claim is positive. It can, however, provide a stronger basis for evaluating those claims.
Focusing on design and high-value customers
Natural-diamond retailers are also concentrating on categories where rarity, service and design matter more than price comparison alone.
This can include:
- Custom jewellery
- High jewellery
- Fancy-colour diamonds
- Provenance-led collections
- Distinctive designer settings
- Anniversary and self-purchase jewellery
Why Lab-Grown Diamonds Are Also Facing Pressure
Lab-grown diamonds are disrupting natural diamonds, but the lab-grown sector has its own challenges.
Production is technology-driven. As equipment, expertise and manufacturing efficiency expand, more diamonds can enter the market. This has contributed to significant declines in wholesale prices.
Lower prices benefit buyers seeking size and design flexibility, but they can create problems for:
- Growers with high production costs
- Wholesalers holding older inventory
- Retailers that bought before another price decline
- Consumers expecting strong resale value
- Brands competing mainly through carat size and discounts
This means lab-grown popularity should not be confused with stable financial value.

Are Lab-Grown Diamonds Better Quality?
No diamond origin is automatically higher quality.
Laboratory-grown diamonds are produced under controlled conditions, but they can still contain growth-related features such as:
- Metallic inclusions in some HPHT-grown diamonds
- Graphitic inclusions
- Colour zoning
- Graining
- Growth strain
- Transparency concerns
- Evidence of post-growth treatment
Natural diamonds also occur across a wide range of colour, clarity, transparency and cut quality.
The Gemological Institute of America explains that natural and laboratory-grown diamonds have essentially the same chemical composition and crystal structure and very similar optical and physical properties. Their growth histories and certain identifiable features differ.
Brilliance, fire and scintillation depend heavily on cut, proportions, symmetry, polish, transparency, lighting and cleanliness—not origin alone.
Compare individual stones rather than assuming that laboratory production or geological formation guarantees a better diamond.
Our lab-grown diamond clarity guide explains why a grading label should be considered alongside visible appearance.
Are Lab-Grown Diamonds Automatically Ethical or Sustainable?
No.
A lab-grown diamond avoids the excavation required to mine that individual stone, but production still requires electricity, specialised equipment, gases or other raw materials, cutting, polishing, transportation and labour.
The finished jewellery also includes:
- Gold or platinum sourcing
- Accent stones
- Manufacturing conditions
- Packaging
- International delivery
- Repairability and product longevity
Environmental performance varies according to the production facility, energy source, manufacturing efficiency and complete supply chain.
Natural-diamond sourcing also varies. Some diamonds may be accompanied by detailed provenance and supply-chain information, while others may offer limited visibility beyond standard legal assurances.
Buyers should ask for specific, supportable evidence rather than assuming that either origin is automatically ethical, sustainable or conflict-free.
Useful questions include:
- Where was the diamond produced or mined?
- Can its origin be documented?
- What is known about energy use or mining practices?
- Where was it cut and polished?
- What information is available about the metal?
- Are environmental claims independently supported?
- Can the jewellery be repaired and worn long term?
What the Changing Market Means for Natural-Diamond Buyers
Current market pressure may give buyers more opportunity to compare prices and negotiate in some commercial natural-diamond categories.
Before purchasing, consider:
- Whether natural origin is personally important
- Whether the seller provides useful provenance information
- How the diamond compares with similar natural stones
- Whether the price reflects rarity, quality, design or brand
- The reputation of the grading laboratory
- The ring’s craftsmanship and setting security
- Return, resizing, warranty and upgrade policies
A natural diamond generally has a more established secondary market than a lab-grown diamond. However, retail diamond jewellery should not be presented as a guaranteed investment or as certain to retain its original purchase price.
What the Changing Market Means for Lab-Grown Buyers
Lab-grown buyers can benefit from lower prices, larger available sizes and greater flexibility for customised or diamond-intensive designs.
They should also understand:
- Comparable new stones may become less expensive later.
- Resale offers may be substantially below the original retail price.
- Quality still varies between individual diamonds.
- The laboratory document should be verified independently.
- Growth method and post-growth treatment may be disclosed.
- The setting and craftsmanship remain major parts of the finished piece’s value.
- Environmental claims require evidence.
Lab-grown jewellery is generally best purchased for its design, appearance and personal use rather than expected appreciation.

Natural vs Lab-Grown Diamonds: Buyer Decision Table
|
Final Perspective
Lab-grown diamonds have become a major competitive force, particularly in bridal jewellery and other categories where buyers compare size and price directly.
They have contributed to pressure on commercial natural diamonds and forced producers and retailers to reconsider supply, marketing, provenance and customer education.
But the natural-diamond industry’s difficulties cannot be attributed to lab-grown diamonds alone. Weak Chinese demand, excess inventory, economic uncertainty, trade complications and changes in luxury spending also play important roles.
Natural diamonds are unlikely to disappear. Their market is becoming more concentrated around rarity, documented origin, high-value design and buyers who value geological formation. Lab-grown diamonds are likely to remain important for buyers prioritising size, affordability and design freedom.

Explore Lab Grown Diamond JewelryFrequently Asked Questions
Are lab-grown diamonds causing natural-diamond prices to fall?
Lab-grown competition contributes to price pressure, particularly in commercial engagement-ring categories. However, weaker Chinese demand, excess inventory, economic uncertainty, trade costs and changing luxury spending have also affected natural-diamond prices.
Is the natural-diamond industry collapsing?
The industry is under serious pressure, and some producers have reduced output, paused projects or restructured operations. However, natural diamonds continue to generate substantial retail revenue, particularly in higher-value categories. The market is changing rather than disappearing completely.
Are lab-grown diamonds replacing natural diamonds?
Lab-grown diamonds are gaining unit share, especially in bridal jewellery, but they are not replacing natural diamonds in every category. Natural diamonds continue to serve buyers prioritising geological rarity, provenance, premium design and established tradition.
Are lab-grown diamonds better quality than natural diamonds?
No. Both categories contain a range of colour, clarity, cut and transparency levels. A controlled production environment does not guarantee superior quality. Buyers should evaluate the individual diamond and its documentation.
Are lab-grown and natural diamonds identical?
They have essentially the same chemical composition and crystal structure and very similar optical and physical properties. Their growth histories differ, and specialised gemological testing can identify their origin.
Are natural diamonds a good investment?
Natural diamonds have a more established secondary market than lab-grown diamonds, but ordinary retail diamond jewellery is not guaranteed to retain or increase its purchase value. Quality, brand, provenance, condition and selling costs all affect resale offers.
Do lab-grown diamonds have resale value?
They may receive a resale or trade-in offer, but the amount can be substantially below the original retail price. Declining replacement costs for comparable new stones can place pressure on secondary-market offers.
Which type of diamond is better for an engagement ring?
Neither is universally better. A natural diamond may suit someone who values geological rarity and provenance. A lab-grown diamond may suit someone prioritising larger size, design flexibility and lower upfront price. Setting quality and seller policies matter in both cases.
Are lab-grown diamonds automatically more ethical?
No. Lab-grown origin avoids mining that particular stone, but energy, labour, cutting, metal sourcing and transportation still matter. Ethical and environmental claims should be supported with specific supply-chain evidence.
Will natural-diamond prices recover?
Future prices cannot be predicted with certainty. Recovery will depend on consumer demand, supply discipline, Chinese luxury spending, economic conditions, inventory levels and competition from laboratory-grown diamonds.
