In the diamond business,

trust is everything.



RT Diamond continues a tradition of trusted professionals lasting 5 generations. Roy Travin, RT Diamond's CEO is a descendant of one of the most respected families in the Diamonds business. The family were among the founders of the Diamond Exchange in Israel in the middle of the 20th Century.


Roy Travin made his first steps in the business at an early age as a teenager in Israel gaining expertise in all aspects of the trade from evaluating rough diamonds, through design and polishing, to trading and working with precious metals. In the early 2000s, he decided a unique opportunity exists to bring the traditions and expertise he learnt at home to Japan. He moved to Tokyo and built a name for himself as a unique professional in the local diamond market.

At RT Diamonds, we live and love diamonds and are always happy to share our expertise on any opportunity. Our door is open and we treat every client with respect and friendship this is what we learned at home. In keeping with tradition, our priority is to build long-term relationships based on honesty and trust.
