Pearl Color: Natural Iridescent Pearl Size: 7-7.5mm Pearl Grade: Luster AAAA+/ Nacre AAAA/ Blemish AAA Metal Fittings: s925 Earring backs are included. Non-nucleated pearls, compared to common Akoya pearls, have a thicker nacre layer, so their luster does not diminish over time. These are pearls formed without a nucleus. The nucleus is inserted during cultivation, so natural pearls are non-nucleated pearls. Even in cultured pearls, keshi pearls, which are formed when a piece separates from the nucleus, or those made by inserting only a piece instead of a nucleus, are considered non-nucleated pearls.
