Remember that one company's AAA may not be the same as another company's AAA. The AA of one company may be better than the AAA of another company. The grading isn't standardized the way it is for, say, diamonds.
That said, generally the surface luster of the best Akoyas will be greater than that of the best freshwater pearls. Akoya pearls are cultured in colder waters and the nacre is laid down more slowly, resulting in a different, sharper sort of luster than CFWP. But the CFWP are solid nacre, so their luster is deeper.
That is a generalization. There are rare, fancy colored ''exotic'' CFWP that are have a metallic shine to them. But usually their luster is softer. |
