60 years of history, achievements, and trust.
Our company began importing and selling industrial diamonds from the UK in 1953, and now also imports from Belgium and the United States, making significant contributions to the development of key sectors in Japanese industry, such as the automotive industry, semiconductor-related industries, and ultra-precision component processing. Since diamonds are natural, each one has different characteristics and features, making experience a significant factor. Leveraging our 60 years of history, achievements, and trust, we operate under a consignment sales system for imports, relying solely on our credibility.
