The morphology of diamond can be classified into single crystals, intergrowths, and polycrystalline aggregates. Single crystals can be further divided into cubes, octahedra, and rhombic dodecahedra. The image below shows the crystal morphology of synthetic diamonds, among which the hexoctahedral form* is the most common. Synthetic diamond single crystals exhibit planar surfaces with distinct crystal edges and vertices.

Static Pressure Catalytic Method

It refers to the method of synthesizing diamond under thermodynamically stable conditions, with constant ultra-high pressure and high temperature, and in the presence of a catalyst.
