    摘要: A high pressure apparatus for the manufacture of diamonds includes a pressure chamber formed of holes in annular, disc-like members arranged one after the other and a pair of opposed pressure-exerting members movable into the chamber formed by the holes with compressible gaskets arranged between adjacent disc-like members. The pressure exerting members are frusto-conical and the ends of the holes adjacent these members are similarly shaped.
