Diamond Industry 2026- Ten Forces Reshaping the Trade

13

Gems News: The global diamond industry is entering 2026 in a dramatically altered state after three punishing years that rattled every link in the supply chain. From miners and manufacturers to wholesalers and retailers, few participants have been spared the squeeze that began in 2023 and persisted through 2025. What lies ahead is not a swift rebound, but rather a year defined by recalibration, strategic repositioning, and a search for long-term stability in a smaller, more disciplined market.

While some industry insiders had hoped for a cyclical recovery, the structural pressures weighing on the trade remain firmly in place. Retail contraction in key markets, shifting consumer priorities, and the ongoing rise of lab-grown alternatives continue to reshape the competitive landscape. This Gems News report examines the ten defining forces expected to influence the diamond trade in 2026 and beyond.

A Smaller, Leaner Market

The first and most visible shift is contraction. The US jewelry sector, still the world’s largest diamond-consuming market, continues to shrink by roughly 3% annually as independent jewelers close their doors, often without succession plans. Yet store closures tell only part of the story. Retailers are also rebalancing their product mix, allocating more space to synthetic diamonds and higher-margin gold jewelry, especially as elevated gold prices force difficult inventory trade-offs.

This tightening demand environment is cascading upstream. Manufacturers and dealers are feeling the pressure, and weaker players are exiting the business. The result is a leaner industry, focused less on scale and more on sustainability.

Power Shifts in Rough Distribution

The traditional dominance of De Beers in signaling pricing and supply trends is gradually diminishing. As the company reduces output and streamlines its sightholder base, alternative suppliers are gaining influence. Botswana’s Okavango Diamond Company is expanding contract sales, Angola is strengthening its structured sales approach, and Alrosa continues placing significant volumes into the market.

This diversification of supply channels weakens centralized pricing signals and creates a more fragmented rough market.

Botswana’s Expanding Influence

Anglo American’s planned sale of its majority stake in De Beers will likely elevate Botswana’s role in global diamond marketing. The government is poised to expand its influence, potentially taking a majority position and asserting greater control over how its diamonds are positioned worldwide.

Consumers Choose Experiences Over Gems

Another powerful force reshaping demand is consumer preference. After pandemic disruptions temporarily paused travel and entertainment, spending has once again tilted toward experiences rather than physical goods. Luxury travel, fine dining, and high-profile events dominate social media feeds, influencing aspiration across income groups.

Ultra-wealthy buyers continue to flaunt bespoke experiences, while Gen-Z consumers channel discretionary budgets toward adventure and lifestyle moments. Jewelry purchases are becoming more selective, and impulse buying has slowed. Affordable luxury, which thrived in the immediate post-pandemic years, is losing momentum as buyers grow more discerning.

Synthetic Pricing Pressures Build

Lab-grown diamonds remain a disruptive force. Wholesale prices have declined sharply, yet retail prices have not fallen proportionately, creating unusually high margins for sellers. However, inconsistencies across online platforms, department stores, and branded retailers are becoming more visible to consumers.

As awareness grows, downward retail price pressure is likely to intensify, potentially eroding margins and destabilizing the current pricing structure in the synthetic segment.

Value Takes Priority Over Volume

For decades, the diamond business chased volume. In 2026, the focus shifts toward value extraction. Retailers face a strategic crossroads: push higher volumes of lower-priced synthetics or champion natural diamonds as rarer, higher-value propositions. Attempting to balance both models is increasingly complex, particularly for independent jewelers who lack the scale to segment their branding effectively.

Reinforcing scarcity and protecting pricing integrity are becoming central themes for natural diamond advocates determined to preserve long-term brand equity.

Supply at Multi-Decade Lows

Global rough diamond production fell to around 100 million carats in 2025, marking multi-decade lows. That reduced output is expected to persist into 2026. Lower supply reflects weaker demand and a more cautious approach by producers seeking to avoid flooding the market.

Renewed Marketing Efforts

Recognizing that demand will not automatically rebound, industry stakeholders are increasing support for category marketing. Funding for the Natural Diamond Council is expected to rise, partly driven by pledges under the Luanda Accord. Even so, the organization remains underfunded relative to its stated goals, limiting the scale of global campaigns needed to meaningfully shift consumer perception.

Traceability as Storytelling

In 2026, traceability will pivot from regulatory compliance toward brand storytelling. With sanctions-related pressure easing under self-declaration mechanisms adopted by G7 nations, provenance will become a marketing tool rather than merely a compliance requirement. Brands will emphasize origin, ethics, and authenticity to differentiate natural diamonds in a crowded marketplace.

Terminology Tightens

Finally, language itself is becoming strategic. The term “synthetics,” once avoided, is re-emerging within industry discourse. With CIBJO expected to move toward reintroducing the term into its lexicon, clearer distinctions between natural and lab-grown stones may shape both regulation and marketing narratives.

The year ahead will not deliver a dramatic rebound, but it will mark a pivotal transition toward a more disciplined, strategically aligned diamond sector. Companies that adapt to selective consumer spending, embrace storytelling, and prioritize value over sheer volume are likely to emerge stronger in a reshaped global market. Structural shifts are no longer temporary disruptions; they are the foundation of a new competitive era.
