✦ Synopsis

A new apparatus of diamond synthesis by electric discharge shock in oil was completed. Synthetic diamonds were made by a spark discharge shock between nickel and iron and an artificial graphite electrode in high pressure kerosene. The discharge energy was about 4000 joules. The identification was made by hardness tests and by an X-ray diffraction pattern. The growth rate of synthetic diamonds is very high. The synthetic diamonds are transparent and slightly yellowish.
