The Pearl Wise Unified Grading System ships in the US for free!
Welcome to Pearl Wise. We feature products developed for the identification, grading, and measuring of cultured and natural pearls. Natural pearls are extremely rare in the modern marketplace, therefore the emphasis is on cultured pearls.
The pearl wise unified grading system combines several systems, which individually have limitations. We have combined grading techniques from the GIA, GemWorld International, Mikimoto, and the Tahitian Government to make our system more comprehensive.
