The corundum market size is expected to see strong growth in the next few years. It will grow to $3.55 billion in 2030 at a compound annual growth rate (CAGR) of 5.3%. The growth in the forecast period can be attributed to expansion of corundum applications in advanced abrasives, growing adoption in high-end jewelry and luxury items, rising demand for microfine and specialty corundum blends, growth in refractory and high-temperature industrial uses, increasing use in electrical, electronics, and specialty manufacturing. Major trends in the forecast period include rising use of brown fused alumina in industrial abrasives, increasing adoption of white fused alumina for precision applications, growth in corundum-based jewelry and gemstones, expansion of high-grade and microfine corundum applications, increasing demand for specialty corundum blends.

The growing demand for gemstones is expected to drive the expansion of the corundum market. Gemstones are crystals that are cut, polished, and used in jewelry and ornaments due to their rarity and beauty. This rising demand is fueled by factors such as increasing consumer interest in luxury and personalized jewelry, higher disposable incomes, and the growing influence of fashion trends. Corundum, which is commonly found in gemstones like ruby and sapphire, is highly valued for its exceptional hardness and vibrant colors. These gemstones are prized in the jewelry industry for their aesthetic appeal and durability. For example, in July 2024, Rapaport USA Inc., a US-based organization focused on the diamond and jewelry industry, reported that Russia's diamond production in 2022 reached 41.9 million carats, valued at $3.55 billion, with an average price of $85 per carat, compared to 37.3 million carats of rough diamonds produced the previous year. As a result, the increasing demand for gemstones is driving the growth of the corundum market.

Major players in the corundum market are investing in advanced solutions such as high-tech gem testing laboratories, which make gem analysis more accessible and cost-effective. For example, in February 2023, GGTL Laboratories, a gemological lab based in Switzerland, opened the GGTL Gemlab in Antwerp, Belgium. This facility boasts cutting-edge technology for the analysis of melee-sized gemstones and offers comprehensive testing services including authenticity and origin verification for sapphires and rubies.
