Quality Providing Diamonds with the Highest ‘Ultimate’ Rating
Going beyond the traditional diamond quality evaluation criteria of “4Cs,” the company implements the new “Sarine Report” which evaluates a diamond’s brilliance. Even among diamond roughs selected from leading polishing companies worldwide, the highest “Ultimate” rating is not common. However, it has been proven that over 90% of the polished diamonds purchased by Ginza Diamond Shiraishi that receive a Sarine Report grade are diamonds with the highest “Ultimate” rating.
Sourcing and Selecting the Highest Quality Diamonds from Around the World
The company has established a local subsidiary, Israel Shiraishi, at the Israel Diamond Exchange, one of the world’s three major diamond markets. With resident buyers constantly checking exchange rates, they can efficiently procure high-quality diamonds.
Ginza Diamond Shiraishi celebrates its 24th anniversary and has been chosen by 450,000 couples to date.
Driven by the desire to “stay close to couples and give shape to their happiness,” the company handles everything from diamond sourcing to design, processing, and sales under an integrated in-house management system. It pioneered the industry with its unique “Semi-Order System,” where customers combine from a rich selection of high-quality diamonds (approximately 8,000 items regularly stocked) and excellent ring designs. The diamonds procured through the local subsidiary Israel Shiraishi are directly sourced and strictly selected by Ginza Diamond Shiraishi’s exclusive resident buyers, who are former diamond appraisers, based on stringent criteria for high quality.
Ginza Diamond Shiraishi is “Japan’s largest bridal jewelry specialty store” that, through diamonds, accompanies customers through various milestones and life stage changes, “giving shape to their feelings.”
