Over 99% of its diamonds have achieved the world's highest evaluation, "Ultimate★★★," on the "Sarine Light" system for measuring and evaluating diamond brilliance, and the company operates 60 stores in Japan (as of June 2026).

World's Highest Evaluation of Brilliance Achieved with "Sarine Light," a Scientific System for Evaluating Diamond Brilliance

*Sarine Light reports are not issued for some diamonds, such as those under 0.25ct, H color or lower, and SI1 clarity or lower.

The "Sarine Light" system was developed to evaluate diamond brilliance with globally established standards. The diamonds of EXELCO DIAMOND were used as "diamonds that set the standard for beautiful sparkle" in the development of this historic device.

With over 99% of EXELCO DIAMOND's diamonds receiving the world's highest "Ultimate★★★" rating from "Sarine Light," you can fully enjoy the authentic brilliance that diamonds inherently possess.

Introducing "Diamond Journey" to Trace the Path of a Single Diamond

"Diamond Journey" is a system that allows you to know what shape the diamond you choose was as a rough stone, how it was cut, and the journey it took to reach you.

It allows you to feel the miracle of its arrival while also serving as proof that it is a natural virgin diamond, not a "conflict diamond" or "reused/recycled diamond."

"Diamond Journey" is the latest technology made possible by our "integrated system" that spans from the selection and purchase of rough stones to sales at our stores.

EXELCO DIAMOND is the first brand in the world to introduce "Diamond Journey."
