SumiCrystal

SumiCrystal is synthetic monocrystalline diamond, that Sumitomo Electric manufactures under strict quality requirements.

Diamonds are famous for being the hardest known material offering a maximum of heat resistance. Due to these characteristics combined with low thermic spread and high electric resistance diamonds are important for today's high-precision technologies. Compared with natural diamond SumiCrystal shows up an excellent uniformity of product characteristics and is therefore very much suited for industrial applications.

SumiCrystal is synthetic single diamond which Sumitomo Electric succeeded in mass production for the first time in the world. SumiCrystal manufactured under severe quality, so it's suitable for industrial materials.
