The global diamond industry is undergoing unprecedented restructuring amid high-quality resource scarcity, supply realignment, and value chain reshaping. Post-2022 peak, natural diamond prices remain under pressure; De Beers cut rough diamond prices in Jan 2026 (10%-15% drop expected), marking its 3rd year of reductions. Meanwhile, lab-grown diamonds dominate over 40% of 2025 global jewelry sales, an 8-fold increase from 2019.
Market divergence is stark: large, high-quality natural diamonds retain pricing power due to irreplicable scarcity, while small, consumer-grade diamonds face steep adjustments. Amid this shift, SACIM SARL’s Tshibwe Kimberlite Pipe Diamond Mine stands out with world-class reserves.

Global Scarcity AnalysisAgainst widespread resource depletion in traditional global diamond mining areas, the scarcity value of the Tshibwe Mine is prominent.
- Traditional mine depletion: Australia’s Argyle Mine closed in 2020, cutting annual supply by over 10 million carats; South Africa’s old mines face deeper mining and rising costs.
- Supply contraction: Global natural diamond output is projected at 105–125 million carats annually, with no strong growth momentum.
- Intensified market divergence: In 2025, prices of consumer-grade diamonds below 0.5 carats dropped over 20% for the full year, while high-quality diamonds above 3 carats fell by only 0.4%.
Boasting unique strengths of large reserves, high grade and long service life, the Tshibwe Mine has become a scarce primary diamond incremental asset in global diamond supply.
