The Pearl Nacre Thickness
The Pearl Nacre ThicknessA bead-nucleated cultured pearl will look shiny and the surface flawless when it is freshly harvested, however, if the pearl nacre (the real pearl substance surrounding the bead) is not thick enough, after a period of time (depending on how often you wear it), the varnish will flake or even eventually peel off. Thin nacre is always a potential problem when buying bead-nucleated saltwater pearls. This is not usually a problem with Tahitian or South Sea pearls because of their larger sizes; nor is it a problem with freshwater pearls which are composed of solid pearl nacre without containing a bead nucleus. |
