2019年10月26日 · 天女，由日本真珠科學研究所命名，白色系akoya珍珠中的卓越品質を代表する。 下半球會出現3種干涉色、即ち“極光效王”。 具備“極光效王”のあこや珍珠及び直徑在6mm以上、即命名為“極光天女”、一般簡稱為“天女”。 關於珠層： 天女珠層の標準為0.4mm，0.4mm以下の不可評価為天女。 很多賣家宣稱，珍珠層越厚珍珠光澤越美，很多買家も深為然。 珠層並非越厚光澤好，珠層厚並光澤，瑕畝有直接聯繫。 決定珍珠光澤は珍珠質層結晶層間の配列加重が平坦密であるかどうかです。 例例，就如同層一層的磚塊疊加，磚塊集合列整齊緊密，那這面牆就平整筆直而結實，如果磚塊排列不整齊，那這面牆就會凹凸不平很不美観。 如果珍珠層單層像這樣整齊緊密的結合在一個，那麼整個珍珠表面就會呈現完美光滑的狀態。
