The social awareness about responsible consumption among younger generations also significantly contributes to the demand for lab-grown diamonds. Consequently, Japan lab-grown diamonds market is estimated to flourish, reflecting changes in consumer preferences and values in the country’s luxury goods sector.

For instance, in September 2024, EDP Corporation, a Japanese firm specializing in lab-grown diamond production, acquired Lusix, an Israel-based lab-grown diamond company, for around USD 2.5 million. This deal marked a positive landmark for the expedition in Japan's growth rate of lab-grown diamonds. EDP's capabilities in making diamond seeds will increase the strength of local production capabilities and raise social awareness and innovation of lab-grown diamonds in the country. Moreover, Lusix's operations were retained by EDP Corporation to meet the increasing consumer demand for sustainable and ethically sourced diamonds in Japan.

Rapid Technological Advancements in Lab-Grown Diamonds Spearhead the Market Expedition

Synthetic diamonds are a technological breakthrough in Japan's lab-grown diamond industry. Japan has shown remarkable improvements in quality and affordability, making lab-grown diamonds almost indistinguishable from natural ones. These advancements improve the clarity of the diamonds and promote sustainable practices by reducing environmental impact. As consumer demand for ethical products grows, Japan's leadership in synthetic diamond technology positions it to meet consumers' preferences and fuel growth and innovation in the market.

For instance, in September 2024, Japan’s Saga University created a breakthrough in the application of synthetic diamonds for power semiconductors, where the diamonds exhibited remarkable properties, such as having 33 times the electrical strength and five times the thermal tolerance compared to silicon. The advancement positioned synthetic diamonds as the next best alternative for future semiconductors with potential applications in electric vehicles and charging stations. The most recent examples are the world’s first use of a power circuit based on diamond semiconductors and the high-volume production of large-size diamond wafers by companies such as Orbray Co. Ltd located in Tokyo. The commercialization of this technology marked a transformative shift in the country’s semiconductor materials.

Utilization of Lab-Grown Diamonds in the Automotive Industry Augments Market Growth

Lab-grown diamonds are significant to Japan's automotive industry as they are characterized by some unique properties and sustainability advantages. Lab-grown diamonds formed via advanced techniques such as Chemical Vapor Deposition (CVD) and High-Pressure High Temperature (HPHT) possess remarkable hardness and thermal conductivity, making them suitable for applications in cutting tools, machinery components, etc. Moreover, the lab-grown diamonds perfectly align with the shift of the country’s automotive sector towards eco-friendly practices as they reduce dependence on mined resources.

Additionally, lab-grown diamonds' cost-effectiveness and ethical appeal resonate with an increasing consumer base that values sustainability. As much as integrating lab-grown diamonds enhances the performance of automobiles, it represents supporting innovation and environmental commitment. This improves product performance and supports innovation and environmental responsibility in a way that makes the country stand at the forefront of sustainable material utilization within the automotive industry. The trend thus represents one step in a larger approach of integrating advanced materials within industries, pointing to the ability of lab-grown diamonds to greatly transform the automotive sector of Japan and yield substantial market growth in the future.

The Advent of Colored Lab-Grown Diamonds is Expediting the Market Prospects

The emergence of colored lab-grown diamonds is expected to accelerate the growth rate of the market exponentially. As today's conscious consumers are concerned about the detrimental consequences that traditional diamonds sourced from mines can have, colored lab-grown diamonds are becoming a preferable choice among customers due to their ethically sourced nature and call for environmental sustainability. The possibility of producing all sorts of colors through controlled processes allows for customization toward different consumer preferences. Moreover, colored synthetic, lab-grown diamonds are relatively cheaper than natural stones, making them affordable for a larger number of consumers, thus driving demand and creating an expansion in Japan’s jewelry. Moreover, Japanese companies focus on campaigns and events abroad for lab-grown diamonds to promote the brands, educate consumers on ethical and sustainable practices, and capitalize on international markets.

For instance, in November 2024, Japan's First Lab-grown diamond jewelry brand, SHINCA (marketed by Imayo & Co., Ltd), announced its first pop-up event in Singapore. The pop-up event featured a wide variety of colored lab-grown diamond rings, highlighting the vibrant color options available in the store. With the availability of a variety of colors that mirror current trends in sustainable jewelry design, the event undeniably paved the way for improved customer experience and awareness of lab-grown diamonds.

Southern Japan Emerged as the Market Leader

The southern region of Japan has significantly dominated the market and is expected to continue to do so in the coming years. This is owing to higher consumer consciousness of sustainable, ethical values and development in production techniques of lab-grown diamonds via CVD, which increases the quality of cultured diamonds and makes them much more affordable. Local manufacturers also actively promote the products using innovative marketing strategies, making them highly visible. Moreover, businesses and research institutions have been working in collaboration with each other for the advancement of lab-grown diamonds, thereby positioning Southern Japan as the largest hub for lab-grown diamonds in the country.

Furthermore, Kyushu emerged as the most prominent region of southern Japan. This region is recognized for its blend of traditional craftsmanship and innovative industries and is fostering an emergent demand for lab-grown diamond products. Additionally, local manufacturers and retailers actively promoting these diamonds contribute to Kyushu's strong market position, thus positing the southern region as a major hub in Japan for the lab-grown diamond industry.

Future Market Scenario (FY2025 – FY2032F)

• While traditional diamonds have deep cultural value in Japan, the growing acceptance of lab-grown diamonds is a clear indication that consumer attitudes are changing. The interplay between established luxury perceptions and emerging demand for sustainable options creates a dynamic market environment that will likely continue with the evolving changes in consumer preferences.
• Innovations in lab-grown diamond production technologies, including Chemical Vapor Deposition (CVD) and High Pressure and High Temperature (HPHT), are improving the quality and variety of lab-grown diamonds available in Japan. These innovations have made it possible to create diamonds that are comparable in beauty and durability to natural stones while reducing production costs, thus making them more accessible to consumers, which in turn, will cater to ample opportunities for growth over the upcoming years.
