| gold bracelets Just like any other gemstone, there are quite a few things to know about pearls that can help you not only get the best deal, but the right pearl for you.First, let me start by saying that there is no official grading system industry wide for pearls. There are however, 2 different systems that reputable pearl dealers hold themselves to. The first system is the A A A-A system which allows jewelers to grade their pearls. In this system, a grade of A A A means the pearl is of the highest quality watches. The pearl should be nearly flawless and have a very high luster. If the pearl has a grade of AA, it should still have a high luster but could have a defect here or there. The grade of A is the lowest quality pearl. This type of pearl will most likely have a lot of flaws and be lacking luster.The second system widely accepted by pearl dealers is the A-D system, sometimes known as the Tahitian system. This is the system often used to grade Tahitian or South Sea pearls in overseas markets. In this system, a grade of A means the pearl is of the highest quality with high luster and is virtually flawless. The grading goes down from there, with a B pearl having a high to medium luster and a few defects. A pearl with a grade of C will most likely have a medium luster with defects possibly over 50% off the su***ce. Any pearl given a grade below D is not considered usable for jewelry.Because these two grading systems are not industry-wide, it is important that you feel as though you can trust your jeweler. Ask them for the pearl grading in writing, any reputable dealer should provide this. |
