Japan Lab-grown Diamonds Market Size Set to Touch USD 4.2 billion by 2031

Published | 26 May 2025

Japan Lab-grown Diamonds Market is booming primarily due to the soaring demand for ethically and sustainably sourced products coupled with the rising affordability of lab-grown diamonds, their increasing acceptance, and growing awareness among consumers.

BlueWeave Consulting, a leading strategic consulting and market research firm, in its recent study, estimated Japan Lab-grown Diamonds Market size by value at USD 2,367.25 million in 2024. During the forecast period between 2025 and 2031, BlueWeave expects Japan Lab-grown Diamonds Market size to boom at a robust CAGR of 8.45% reaching a value of USD 4,176.87 million by 2031. The Lab-grown Diamonds Market in Japan is propelled by growing ethical and environmental concerns, given that lab-grown diamonds present a sustainable and conflict-free alternative to their mined counterparts. Their enhanced affordability relative to natural diamonds also renders them accessible to a wider consumer base, particularly resonating with younger demographics who increasingly emphasize responsible consumption. This discernible shift in consumer values is fundamentally transforming the luxury goods sector in Japan, consequently spurring strong demand for lab-grown diamonds. A notable strategic milestone occurred in September 2024, with Japan's EDP Corporation's acquisition of Israel-based Lusix for approximately USD 2.5 million. This strategic move is set to significantly augment Japan's domestic production capabilities by synergizing EDP’s specialized expertise in diamond seed manufacturing with Lusix’s established operational framework. Beyond fostering innovation, this transaction is also elevating social awareness concerning sustainable diamond sourcing, thereby accelerating market growth to address the rising consumer preference for ethical and eco-friendly products within Japan.

Impact of Escalating Geopolitical Tensions on Japan Lab-grown Diamonds Market
