China and African Nations Bet Big on Natural Diamonds
BEIJING — September 17, 2026 — In a major move to reshape the global gem market, government emissaries from key African diamond-producing nations—including Botswana, Namibia, and South Africa—joined senior representatives from the Shanghai Diamond Exchange (SDE), major Chinese retail conglomerates, and De Beers Group to officially sign the "Beijing Declaration on Natural Diamonds and Sustainable Development".
The landmark pact establishes a formal strategic framework designed to reinvigorate mainland China's natural diamond demand ahead of the fourth-quarter holiday season. By connecting source-country values directly with East Asian retail channels, the initiative aims to counter recent headwinds in domestic retail sales and shifting demographic trends, such as declining marriage rates.
Rebuilding Demand Through Value and Traceability
Aligned with the United Nations Sustainable Development Goals (SDGs) and the African Union's Agenda 2063, the Beijing Declaration focuses on mine-to-market traceability, localized economic development, and cultural storytelling. The strategy centers on educating Chinese consumers—who are increasingly prioritizing natural origin, authenticity, and provenance over mass-market synthetic alternatives—about the tangible human-interest and environmental impacts of natural gems, including biodiversity conservation and community support across African mining states.
Major diamond producers, led by De Beers Group, along with premier Hong Kong-headquartered retail giants—including Chow Tai Fook, Lukfook, and Chow Sang Sang—have strongly endorsed the agreement as a vital catalyst for the region’s jewelry sector.
Strategic Benefits for Hong Kong’s Gem Trade
Sourcing Hub Advantage: As the primary trade gateway and tax-free clearance hub for gems entering Mainland China, a surge in mainland retail appetite directly drives trading volumes, re-exports, and order books at major international trade events like Jewellery & Gem WORLD (JGW) Hong Kong.
Boost for Hong Kong Retail Conglomerates: Given their massive retail footprints across Mainland China, Hong Kong-listed jewelry giants stand to capture high-margin retail revenues as consumer sentiment shifts back toward natural diamonds.
B2B Settlement & Wholesale Consolidation: While Shanghai leads the domestic marketing and consumer policy framework, Hong Kong remains the preferred international venue for tax-free gem trading, foreign currency settlements, and high-value wholesale transactions.
China’s Dual-Track Strategy on Lab-Grown Diamonds
The signing of the declaration also highlights China's distinct, dual-track approach to lab-grown diamonds (LGDs), sharply differentiating industrial applications from retail jewelry:
High-Tech & AI Industrial Focus (Government Backed): China continues to heavily support synthetic diamond production, particularly in Henan province, which accounts for over 60% of global LGD output. However, Beijing has shifted its strategic priority away from fashion accessories and toward high-tech applications. Capitalizing on diamond's unmatched thermal conductivity, major producers (such as Liliang Diamond) are redirecting capital into R&D for AI chip thermal management, semiconductor cooling, laser optics, and precision tooling.
Jewelry Market Segmentation & Regulation: Following severe overcapacity, Chinese regulators are taking active steps to prevent market flooding and protect luxury value. State-backed platforms like the SDE are enforcing strict labeling and transparent disclosure rules—prohibiting misleading descriptors like "cultured" without qualifiers. Through initiatives like the Beijing Declaration, the state is effectively partitioning the market: natural diamonds are positioned as rare, high-value luxury assets, while lab-grown gems are relegated to low-cost, fashion-driven lifestyle accessories.
