Pearl With PSL Certificate or PEPCA Certificate
Some of our pearl jewelry comes with a certificate issued by either PSL (Pearl Science Laboratory) or PEPCA (Japan Pearl Export and Processing Cooperative Association) — two of the most respected pearl grading institutions in Japan.
These certificates provide a formal evaluation of the pearl’s quality, including key factors such as luster, surface, shape, nacre thickness, and overall balance. PSL certificates may also include designations like Hanadama or Tennyo, awarded only to pearls that meet the strictest visual and structural criteria.
We offer certified pieces for customers who value third-party verification and documented quality. Certified items will be clearly noted in the product description and shipped with the original certificate.
