High pressure presses for making diamonds and other hard, crystalline materials. The high pressure presses may contain varying numbers of moveable press members: e.g., a tetrahedral press will have four press members while a cubic press will have six press members. The high pressure presses are equipped with at least one hydraulic ram to provide forward and reverse thrusting force. The movable press members are positioned to move along a rectilinear path and converge at a common point. The ram thrusting force is distributed to every press member and the movable press members are guided to move in a simultaneous and synchronous manner by interconnected guide plates and slidable guide rods which comprise a guide system. The guide system allows for the elimination of one or more hydraulic rams such that the total number of hydraulic rams normally connected to each of the moveable press members will be less than the number of press members. The resulting high pressure press is therefore smaller, less expensive, and easier to maintain compared to high pressure presses known in the art that include a hydraulic ram directly connected to each moveable press member.
