翡翠自诞生至今一直受到国人的追捧,大家都喜欢漂亮的翡翠,这也吸引了造假者的注意。最早的处理翡翠是什么时候出现在市场的现在已经无从考证,一个普遍的说法是改革开放前后,由于国内需求的强势扩张使得香港商人嗅出了其中的商机,他们开始研究如何提高低档翡翠的市场价值,最直接的方法就是用化学处理的方法增加翡翠的水头从而大幅提高翡翠的商业价值。造假和鉴定一直都是矛与盾的关系,但是在红外吸收光谱检测出现之前造假都是道高一尺魔高一丈的怪像,往往新的造假方法出来很久以后大家才研究出对应的检测方法,这种关系一直持续到现在。

现在大家都认同的翡翠鉴别标准是把翡翠分为ABCD四档,A货翡翠即天然未经人工处理的翡翠,但包括经过烧红的焗色和上蜡等优化过程的翡翠:B货翡翠即经过酸洗充胶处理的翡翠;C货即经过人工染色处理的翡翠;D货即仿制翡翠的翡翠相似品。现在市场上大家最常见到的还是A货,至于B货和B+C货及D货则是旅游点和超市柜台的常客,但需要指出的是还有一种内地市场不常见的翡翠游离于A货和B货及C货之间,如上抛光粉的翡翠和弱酸洗浸蜡的翡翠。这里面对于普通消费者欺骗性最大的是普通的B+C货翡翠和染色石英岩,对于从业者来说容易摔跟头的则是高B和浸蜡翡翠。

1、B货翡翠可能观察到的酸蚀网纹。酸蚀网纹指翡翠在经历酸洗充胶后雕刻抛光加工时由于填充于裂隙中的胶体硬度明显低于周围硬玉精准平特一肖论坛的硬度而被明显切磨更多形成下凹沟槽,这种小沟槽沿小裂隙和颗粒间隙分布,连结起来就形成了蛛网状的表面纹。酸蚀网纹是B货翡翠的重要鉴定特征,明显的酸蚀网纹肉眼即可观察到,不明显的酸蚀网纹即使显微镜下没有经验的人也不容易找到。酸蚀网纹的明显与否直接关系到以下因素:

6、B货翡翠的敲击声沉闷。此方法鉴别一般的B货翡翠手镯屡试不爽,但无法鉴别较小的翡翠挂件和翡翠戒面以及做工很好的高B翡翠。B货翡翠手镯的敲击声多为沉闷嘶哑,不够清脆,与天然翡翠截然不同,反而类似于天然水沫玉手镯的声音。若用此方法鉴别挂件时,不能用手持住玉件,最好把玉件用细线吊起,用一另块实心的玉件轻轻敲击。需要注意的是天然翡翠如果有裂纹,或者质地疏松也会出现嘶哑和沉闷的敲击声。高B翡翠由于使用了高强度树脂胶之后,充胶量也较少,这样的B货翡翠手镯的敲击声音清脆度和A货翡翠几无区别。

B+C货翡翠的颜色色调往往过于鲜艳,如染绿色则往往是偏黄色的阳绿和浅绿色较多,染紫色则是天然翡翠罕见的比较浓的紫色较多,染红色则是比较鲜艳的红色,往往都背离了天然的颜色分布规律,如天然红翡一般都伴随较灰或较黄的颜色,但近年也出现了染出的偏蓝或偏灰的绿色。

B+C货翡翠的颜色放大观察或者仔细观察时可能发现染的颜色都是丝瓜瓤状结构的细丝沿颗粒间隙和颗粒表面分布,透射光下尤其明显,这点和天然翡翠色根的颜色脉状分布的形态截然不同。
