Corundum Market to Reach USD 11.0 Billion by 2035 Driven by Rising Demand in Jewelry and Industrial Applications

The global corundum market is set to expand from USD 6.7 billion in 2025 to USD 11.0 billion by 2035, recording a 5.1% CAGR over the forecast period. This growth reflects corundum’s pivotal role in diverse sectors ranging from jewelry and gemstones to abrasives, electronics, refractories, and precision tools.

Corundum, recognized as one of the hardest minerals after diamond, is prized for its durability, optical clarity, and chemical resistance. Its applications stretch beyond gemstones such as sapphires and rubies, extending into industrial uses where performance and resilience are critical.

Why the Corundum Market is Growing

The corundum market is gaining traction thanks to advances in synthetic production and increasing adoption in precision-driven industries.

• Industrial demand: Corundum’s use in abrasives, cutting tools, refractories, and electronics has surged due to its high hardness and thermal stability.
• Jewelry demand: Synthetic sapphires, rubies, and rare varieties like padparadscha are increasingly popular in high-end jewelry markets.
• Innovation: Manufacturers are investing in advanced processing technologies, enhancing the uniformity, durability, and performance of synthetic corundum for specialized uses.
• Sustainability: Companies are developing eco-friendly production processes, minimizing waste and enabling longer-lasting products.

Together, these factors have positioned corundum as both a luxury material and an industrial necessity.

Segmental Insights

Sapphire Leads the Market

The sapphire segment will account for 48.3% of the market in 2025, supported by demand in electronics, optics, semiconductors, and jewelry. Synthetic sapphire is particularly valued for its optical clarity, hardness, and thermal resistance, making it indispensable in smartphones, LED substrates, and precision engineering tools.

Abrasive Applications Dominate

The abrasive application is projected to capture 29.5% of revenue share in 2025, driven by its role in cutting, grinding, polishing, and finishing across industries. Corundum-based abrasives improve production efficiency, reduce tool wear, and enable eco-friendly manufacturing with minimal waste.

Jewelry and Specialty Applications

Beyond sapphires and rubies, rare corundum gemstones like padparadscha are gaining traction among luxury buyers for their unique hues. Meanwhile, industrial-grade corundum supports applications in refractories, medical tools, and high-precision milling equipment, reinforcing its dual value in luxury and utility markets.
