In the Pacific, many small islands have been transformed from obscurity to thriving pearl farms that improve the lives of local residents, all thanks to Saburo Nishimura. He traveled by helicopter, searching and pinpointing locations in the ocean, setting up farms, and imparting knowledge. He is like a living encyclopedia of pearls, spreading his knowledge to those in need.

Nishimura’s influence on the pearl industry is monumental. With a meticulous eye for detail and an unwavering commitment to quality, he has been pivotal in establishing rigorous standards that are revered worldwide. His approach combines a deep scientific understanding with a craftsman’s touch, ensuring that each pearl meets a set of criteria that is as stringent as it is transformative. This has not only elevated the quality of pearls on the market but also set a benchmark that others strive to reach.
