光泽度对于珍珠来讲是至关重要的。珍珠越有光泽,价值也就
越高。把珍珠放在灯光下观察珍珠的表面,可以清楚的看到珍珠
表面是否光滑无瑕,越圆润光滑的珍珠光泽度就越高。不同种类
的珍珠所折射出来的光是不同的。在众多海水珍珠中,欧卡娅珍
珠(Akoya)有着较高的光泽度,但其他种类的珍珠也有各自的
优点。
一颗珍珠的价值要从各个角度来观察,包括光泽度、珍珠层的
厚度、大小及形状、颜色和质量等。
Luster might be the most important factor of all. Luster
is the amount of light a pearl reflects. Pearls with high luster have
sharp bright reflections on the surface. Different pearl types have
different standards for luster. Among all types of salt water pearl,
Akoya pearl often shows high luster.
The qualities that determine a natural or cultured pearl’s
value are luster, nacre quality, size, shape, color, and surface quality.
