Editor’s Note
This analysis highlights the rapid expansion forecast for Japan’s lab-grown diamond sector, driven by consumer demand for sustainable luxury. The projected growth underscores a significant shift in market preferences.
The Japanese lab-grown diamond market, valued at USD 511 million in 2024, is projected to reach USD 2.2429 billion by 2033, indicating significant growth. This expansion corresponds to a Compound Annual Growth Rate (CAGR) of 16.77% during the forecast period from 2025 to 2033. Lab-grown diamonds are gaining momentum in the Japanese market due to their composition, which mirrors the appearance and structure of natural diamonds, coupled with increasing consumer interest driven by sustainability and advancements in manufacturing technology.
One of the primary drivers for the growth of Japan’s lab-grown diamond market is the increasing use in various industrial applications. Known for their superior hardness and strength, these diamonds are widely adopted in industries such as automotive, electronics, and manufacturing for tasks like cutting, drilling, grinding, and polishing. Their high thermal conductivity also makes them ideal for inclusion in electronic devices like diode lamps and computers where heat dissipation is critical. These advantages are propelling market expansion and are expected to contribute significantly to the market’s growth in Japan.
Despite growing interest in lab-grown diamonds, several challenges are hindering the market’s full potential. Competition from alternative products such as natural diamonds and other gemstones like sapphires, emeralds, and amethysts is a significant restraint. Consumers are drawn to these alternatives due to their perceived higher quality, beauty, and durability. Furthermore, concerns regarding the color and longevity of lab-grown diamonds lead to consumer hesitation, with some viewing them as inferior to natural diamonds. Additionally, a widespread lack of awareness about lab-grown diamonds in Japan continues to limit market potential.
A key opportunity for the Japanese lab-grown diamond market lies in the rising trend towards sustainability and ethical consumption. As global demand for sustainable products increases, lab-grown diamonds are becoming the preferred choice due to their environmentally friendly manufacturing processes. Unlike mined diamonds, which require destructive mining, lab-grown diamonds are created without harming forests, reducing air pollution, or contributing to greenhouse gas emissions. Moreover, growing awareness among Millennial and Gen Z consumers about the ethical issues associated with conflict diamonds is driving demand for lab-grown diamonds. This shift towards sustainable practices is expected to bolster market growth during the forecast period.

In terms of technological advancements, the Japanese lab-grown diamond market is segmented into two main categories: HPHT (High-Pressure High-Temperature) and CVD (Chemical Vapor Deposition). In 2024, the HPHT segment held the dominant market share due to its ability to produce superior quality diamonds. This method closely mimics the natural diamond formation process, resulting in diamonds with enhanced clarity, color, and overall quality.
However, the CVD segment is expected to take the lead during the forecast period. Manufacturers are increasingly adopting the CVD method due to its faster production times and greater energy efficiency compared to HPHT. The CVD process’s capability to produce diamonds in a wide variety of colors is driving the growth of this segment, positioning it as a major contributor to the Japanese market.
