Recent progress of the technology of large-scale high pressure apparatus have permitted us to produce synthetic diamond powders in larger quantities at a lower cost. The advances in high-pressure and high-temperature control technique have enabled the commercialization of high-purity large synthetic diamond crystals. In this article, recent advances and future prospects in the high-pressure apparatus technology for synthetic diamonds are described.
