- Chemical and physical properties
Our synthetic monocrystal diamonds are useful across many fields of industry: medicine, machining, test & measurement instruments, automotive industry, optoelectronics, tool-and-die industry, watch and jewellery production. Such a diversified application is based on synthetic diamond properties what are presents in the table below.
