关于选祖母绿的指南

祖母绿属于蓝绿色至绿色绿柱石家族中的一员。色泽可以说是决

定祖母绿的价值和质量的重要因素之一。祖母绿有一系列的绿色色

调:从浅到深的绿色,或是绿中透黄、绿中含蓝。最受众人喜爱的

祖母绿莫过于通透清澈、质地晶莹的纯绿色或是绿中透着淡淡的蓝,

色彩饱和度高,明度不会太亮或太暗,这样的祖母绿才可以冠上价

值高、质地优越的标签。如果色调掺杂着太多蓝色或黄色,那就不

能称为祖母绿,它可能是绿柱石中的其他品种。

Emerald is the bluish green to green variety of beryl

family of minerals. Color is the biggest factor in establishing the

value and quality in natural emeralds. Emeralds come in a range

of green shades, from light to dark with tints of other colors

ranging from yellow to blue. The most desirable emerald

colors are bluish green to pure green with vivid color

saturation and the tone that is not too light or too dark. The

color is evenly distributed. If the hue is too yellowish or too

bluish, the stone is of a different variety of beryl.
