Developed and manufactured the first MPCVD reactor with complete intellectual property rights.
Established in 2013, Ningbo Crysdiam Technology Co., Ltd. is specialized in industrial production and high-end application R&D of CVD lab-grown diamonds. We rank as a leading producer in terms of production scale and technological level. Crysdiam has more than 50 patents and earned the title of National Little Giant, as well as Manufacturing Single Champion and Technological Little Giant of Zhejiang Province; set up Zhejiang Province Diamond Functional Materials and Application Engineering Research Center, Zhejiang Province Postdoctoral Workstation, and Ningbo Academician Workstation; has 4 experts from the National Thousand Talents Program and 3 Academician consultants.
Crysdiam uses Microwave Plasma Chemical Vapor Deposition (MPVCVD) method to grow diamonds, which features stable electrodeless discharge plasma that avoids pollution and has strong controllability of epitaxial growth. The method has good control over the crystal orientation, thickness, and purity of diamonds, and quantitative doping is achievable. In addition to being used for the manufacturing lab-grown diamond jewelry, CVD diamond has excellent application prospects in many high-tech fields such as chips, microelectronics, quantum, optics, ultra precision processing, and high-end medical care.
In 2013, Crysdiam took the lead in developing MPCVD reactor with complete intellectual property rights in China. Additionally, Crysdiam independently developed various types of laser equipment (covering red-light, green-light, purple-light, nanosecond/picosecond/femtosecond, and three-axis/four-axis/five-axis), as well as polishing and grinding equipment. By vertically integrating equipment R&D, diamond production, diamond processing and jewelry manufacturing, Crysdiam can quickly respond to customer needs and provide customized product design and production.
With 1500 MPCVD reactors and a highly equipped state-of-the-art factory, Crysdiam ranks as a leading producer in terms of production scale and technological level. We are able to provide stable supply of lab-grown diamonds of various sizes, shapes and parameters, addressing the concerns of our clients about supply chain stability.
Crysdiam is one of the few CVD producers in the world that can produce lab-grown diamonds with colors of DEF as grown, and our growth technologies of fancy color lab-grown diamonds such as pink and blue are mature. Crysdiam can not only provide customized products according to the needs of our clients, but also offer high quality lab-grown diamonds in calibrated sizes, which can significantly improve efficiency of subsequent jewelry manufacturing processes.
Crysdiam has industrial manufacturing capacity and precision processing capability of large-size and high-quality CVD diamonds, ranking as a technical leader in the industry. At present, the maximum size of our single-crystal CVD diamond reaches 60mm x 60mm. We can carry out quantitative doping with elements such as N and P, achieving high purity diamond of 1ppb. We also have the precision machining ability, achieving diamond surface roughness less than 0.5nm. Our advanced diamond materials can meet the needs of scientific research and industrial applications.
