In the diamond industry, Eiwa Boueki has firmly established its brand as a recutter of diamonds. We are the first to bring into Japan the latest in recutting machines from Israel, and our highly-skilled craftspeople recut diamonds with techniques backed by many years of experience. Those skills have won the trust of many jewelers, and the word in the industry is that, if a diamond recut is entrusted to Eiwa, the diamond’s value will increase by at least one rank if not two.
