OUR STORY
OneFine Materials, a trusted supplier of high-quality large-size laboratory-grown diamonds and solutions in advanced materials, our team formed in 1998. The company was established in 2022, and its headquarters is in Hangzhou, the PRC.
It has established long-term strategic cooperation with several corporations, institutions, and research centers (in America and Japan) worldwide. With their help, our R&D team is constantly optimizing the production process, improving purity and efficiency, and increasing the max size of diamonds. Our CVD rough diamonds can reach 30 carats, and polished stones can be 10 carats plus. More than 95% of our CVD diamonds are above F, VS.
From the start, OneFine Materials derives all its electricity from solar farms to ensure that its energy consumption is nearly 100% accounted for by green electricity. That's significantly reducing emissions and protecting the planet for future generations. Our objective is to live in harmony with nature.
The core values are Curiosity, Creativity, and Integrity.
OUR VALUES
Integrity, Curiosity, and Creativity
Integrity is our first core value and a foundation for others! People tend to have a robust moral code and take responsibility for their actions. As a company, OneFine Materials wants to reflect that same integrity in our business and display our ethical conduct in every decision of ours. It ultimately boils down to making tough choices guided by integrity.
Curiosity, we still have much to learn about best serving our clients—an ongoing openness to learning from our clients to consider how we approach our work carefully.
Creativity is necessary to move from being informed to implementing new solutions. Creativity means considering new angles, trying new things, and moving beyond status.
