Abstract
A method of growing diamond crystals in excess of 10 .mu.m in diameter from industrial diamond "seeds" having mean diameters of approximately 1.5 .mu.m is disclosed. The diamonds are grown by exposing the seed diamonds to C.sub.70 in the presence of reducing agents such as phosphorus or selenium in evacuated cells at moderate temperatures and pressures.
