This article highlights the rising prominence of SMEs in the jewelry sector, driven by their expertise in lab-grown diamond technology. With quality now rivaling natural stones and the market projected to grow 2.5-fold by 2030, these enterprises are reshaping industry dynamics.


Small and medium-sized enterprises (SMEs) are attracting attention in the jewelry industry with their production technology for lab-grown diamonds. In recent years, the quality has improved to the point where it is indistinguishable from natural diamonds. The global market for lab-grown diamonds for jewelry is projected to reach approximately 1.71 trillion yen by 2030, 2.5 times the size of the 2024 market. While lab-grown diamonds for jewelry, once overshadowed by industrial applications, are creating new business opportunities, competition with overseas players is also intensifying.
