Aiming for 3EX Triple Excellent Grade for 100% of Our Diamonds

Diamond cutting is usually performed with the aim of achieving the top grade of 3EX Triple Excellent, which attracts premiums worldwide. However, despite the work being performed by highly skilled and experienced technicians, other companies are only able to achieve grades of EX (Excellent) and H&C for almost half of their diamonds. Here at Eiwa Boueki, taking advantage of our high level of technical expertise, we have achieved a grade of 3EX for almost 100% of our recut diamonds.
