In addition to the traditional diamond quality evaluation standard “4C”, we have implemented a new report “Saline Light Report” that evaluates the brilliance of diamonds. Even among the diamond looses selected from the world’s leading polishing companies, there are not many that are the highest rating Ultimate, but it has been proven that more than 99% of the polished diamonds purchased by Ginza Diamond Shiraishi are the highest rating Ultimate diamonds. We source and select
high-quality diamonds from all over the world.

By consistently purchasing the most beautiful diamonds in the world from all over the world, we are able to offer them at a fair price, and we can even determine the difference in quality that cannot be seen in the appraisal certificate alone before delivering them to our customers.
