Leveraging the comprehensive policy advantages, strategic location, and facilitative international trade environment of the Hainan Free Trade Port, we are dedicated to bringing dazzling lab-grown diamonds to consumers and partners worldwide, serving as a vital bridge connecting "Made in China" intelligence with the global stage.

Our core strength originates from our modern production base in Henan Province.

Our factory utilizes internationally advanced High-Pressure High-Temperature (HPHT) and Chemical Vapor Deposition (CVD) technologies, equipped with state-of-the-art production and inspection equipment. We implement stringent quality control throughout the entire process, from crystal growth to cutting and polishing, ensuring every diamond is optically, chemically, and physically identical to its mined counterpart, exhibiting the same fire, brilliance, and hardness.

The lab-grown diamonds we specialize in are the perfect fusion of modern technology and natural beauty. They not only possess the same physical properties as natural diamonds but also represent the future of a sustainable and responsible jewelry industry through their traceable origins, more environmentally conscious production methods, and exceptional value. Our diverse product range includes everything from loose stones to various finished jewelry pieces, catering to the diverse needs of clients in different markets.
