Spain invests $813m in Diamond Foundry LGD project
In a clear sign of the growing strategic importance of lab-grown diamonds for technological applications, the Spanish government has committed a massive EUR 750 million (approximately $813 million) investment to Diamond Foundry’s new manufacturing plant in Trujillo.
This significant funding injection is specifically earmarked for the production of semiconductor-grade, lab-grown diamonds. It dramatically boosts the project’s war chest, adding to the initial EUR 80 million in funding that the European Union had already pledged last December.
The Trujillo facility is poised to become the largest of its kind in Europe, specializing in high-tech, industrial, and semiconductor-grade diamonds.
- Projected Output: When operations begin—anticipated sometime between 2027 and 2029—the plant is expected to yield over 4 million carats annually, with production slated for substantial increases thereafter.
- Total Project Value: The full cost of the Trujillo project is reported to be a staggering EUR 2.35 billion.
This monumental investment underscores a key trend in the lab-grown diamond sector: a heavy pivot away from the jewelry market and toward high-value industrial and technological applications.

Natural Diamond Market Defies Demand-Supply Dynamics As Prices Continue To Fall
The Diamond Market Continues To Defy Basic Supply-and-Demand Dynamics, Weighed Down By Structural Shifts In Consumer Behavior and Persistent Macroeconomic Pressures.
According to figures from the Kimberley Process, global rough diamond production fell 8% in 2025 to 98.8 million carats, down from 107.9 million carats in 2024. The output marks a significant milestone in the ongoing contraction of the natural diamond mining sector, placing global supply approximately one-third lower than its 2017 high.
De Beers, the world’s premier diamond mining company by value, underscored the depth of the slump in its recent financial disclosures. The industry giant reported that its average realized rough diamond price plummeted 32% in the first half of 2026, falling to $105 per carat.
Under traditional economic principles, a tightening supply chain typically drives prices upward. Yet, the diamond market continues to defy basic supply-and-demand dynamics, weighed down by structural shifts in consumer behavior and persistent macroeconomic pressures.
Industry analysts attribute the sustained drop in realization prices to a confluence of headwinds: Rise of Lab-Grown Alternatives:
Persistent Market Pressures: Changing Consumer Priorities:
With natural supply reaching historic lows and prices remaining under heavy pressure, miners and industry stakeholders face unprecedented pressure to re-calibrate their market strategies and re-establish the value proposition of natural gems in an evolving retail landscape.
