一般来说,天然的祖母绿都含有微小

的瑕疵或是肉眼可见的杂质,一般细微的杂

质是可以为众人所接受的。但如果宝石的缺

陷影响到了整体的美观和宝石的质量,那样

宝石的价值也会随之降低。通透清澈、毫无

瑕疵的祖母绿价格不菲且非常罕见。如果您

看到的宝石是毫无杂质且透亮异常的,那您

应该留个心眼了,因为有可能是人工合成品

或仿制品。

Emeralds by nature contain inclusions that are visible to

the unaided eye. The trade generally accepts eye-visible inclusions

but when the inclusions have a negative effect on transparency

and clarity, or compromise the durability of a stone, they can

lessen the value. Eye-clean emeralds are especially valuable

because they’re so rare. However, any emerald without inclusion

or appears flawless could be suspected to be synthetic or simulant.
