This ultimate wave-line engagement ring sublimates the “natural beauty” of caustics into design through Shiraishi’s pursuit of simplicity and technical skill. The delicate construction allows the center diamond to capture light to the maximum, emitting an even purer brilliance.

*Rings are examples.
Going beyond the traditional diamond quality evaluation standard “4Cs,” we implement the “Sarine Light Report,” a new report evaluating a diamond’s brilliance. Even among diamond rough selected from leading polishing companies worldwide, the highest “Ultimate” rating is not common. Yet, it has been proven that over 99% of the polished diamonds procured by Ginza Diamond Shiraishi are diamonds with the highest “Ultimate” rating.
*Sarine Light Reports are not issued for some diamonds, e.g., those under 0.25ct, H color or lower, clarity SI1 or lower.

By consistently procuring world-class beautiful diamonds from among all diamonds worldwide, we achieve provision at appropriate prices. We discern quality differences not represented by certificates alone and deliver them to our customers.
Ginza Diamond Shiraishi celebrates its 30th anniversary. It is Japan’s first* bridal jewelry specialty store.
Established in 1994 with its flagship store on Ginza Chuo-dori, as of July 2025, it is Japan’s largest bridal jewelry brand with 66 stores domestically. With the sentiment “Diamonds for every bride,” we deliver high-quality diamonds.
The diamonds meticulously selected here are not only evaluated by the “4Cs,” known as the diamond quality standard, but we believe the “brilliance” necessary to feel beauty is the most important value. They are diamonds that emit more beautiful brilliance. It is precisely because it’s Ginza Diamond Shiraishi that you can combine your chosen diamond with your favorite ring design.
We always have over 18,000 diamonds and more than 700 ring designs available, responding to the voices of many brides who say, “I want a ring that is one of a kind in the world, just for me.”
The “Set Ring,” where engagement rings and wedding rings are worn stacked, also pioneered the industry. Smooth wearability and beauty viewed from the side are further features achieved by meticulous handiwork.
Furthermore, permanent after-sales service is provided precisely because we are involved with rings that accompany a lifetime. All of these are the crystallization of our desire to “stay close to the couple and give shape to their happiness,” and the wish itself. Always have been, and always will be.
Ginza Diamond Shiraishi will continue to be a brand that walks alongside the couple’s life journey.
