Unlike diamond that has universal standard quality grading system, there is no industrial standard quality grading system for pearls. Win Pearl adopted A- to AAA+ quality grading system with AAA+ the highest quality and A- the lowest quality. We try to describe our product as accurately as possible. In addition to the quality grade of each product, we have more detailed product description to help our customer make purchasing decision.
