Brand Launch and Concept

DiaM Jewelry, a new jewelry brand for discerning adults that embodies sophistication and aesthetic sense under the concept of “Informed Elegance,” has been launched. Sales began on July 1, 2025, via its official online store (https://diamjewelry.theshop.jp/). The brand offers jewelry featuring both natural diamonds and high-quality lab-grown diamonds, proposing pieces that customers can choose with knowledge of their story and background.

Brand Philosophy: Jewelry with a Story

Jewelry is not merely a decorative accessory to be worn; it is an irreplaceable presence that connects light and stories to the next generation. DiaM Jewelry cherishes two philosophies: “Informed Elegance” and “Legacy & Light.”

“We believe that knowing the background and meaning of a diamond, and the will of the person who chooses it, adds further value to its beauty.”

The brand values both the timelessness of natural diamonds and the innovative nature of lab-grown diamonds. It aspires to be a brand where customers can choose the stone that suits their own story, honoring both craftsmanship passed down through generations and forward-looking, sustainable choices.

Founder’s Message

DiaM Jewelry was born from the concept of “Informed Elegance.”

“For me, elegance is not about wearing expensive things, but about knowing the background and imbuing the reason for a choice with aesthetic sense and thought. Both natural and lab-grown diamonds have different brilliance and meaning. I want to correctly convey these differences and offer the freedom to choose through ‘knowing.’ Jewelry accompanies life’s milestones and connects feelings across time. I hope DiaM’s jewelry will also be such a light, passed on through generations.”
