There is provided a process for growing metastable crystals, e.g., diamonds, from seed crystals at sub-atmospheric pressures and temperatures in the range of from 800 DEG -1,700 DEG C. The process is characterized by the provision of a catalytic, mobile transfer medium as a layer upon the surface of the seed crystal and exposing the catalytically coated seed crystal to a gas containing the crystallizable material under the foregoing conditions of temperature and pressure.
