While there is not currently an enforced universal grading system for pearls, we at PEARLZZZ want to ensure our customers have no doubt about the quality of pearls they are purchasing. Therefore, we grade all our pearls with only the most widely used industry standard grading systems.
For our Freshwater and Akoya pearls, we use the industry standard grading of A-AAAA, with AAAA being the highest quality. For the few, very best quality in the AAAA quality, we grade those as GEM quality for that pearl type. For Freshwater pearls, GEM is also an indicator of the roundest shape possible for Freshwater pearls. For Akoya pearls, since a round shape is standard, GEM is an indicator for having the thickest nacre and cleanest surface for Akoya pearls.For Tahitian and South Sea pearls, there are two grading systems that commonly used. One is mainly used for the exportation of Tahitian pearls, lettered from A-D with A being the highest quality. The other system is the A-AAAA scale, also used for Freshwater and Akoya pearls. Both are widely used in industry grading scales. Because we have such a massive selection and inventory of pearls, we have adapted both scales into one to account for our extensive collection of pearl inventory.
We use a grading scale that ranges from AAAA-D, with AAAA being the highest quality, and D being the lowest quality. Pluses (+) may be used to indicate a slightly higher quality in that level. For instance, AA+ is better than AA. GEM is also used to indicate the absolute highest quality possible in that pearl type (instead of AAAA+), as it is with our Freshwater and Akoya pearls.
