翡翠净度及分级的探讨

Discussion about the Clarity and Grading of Jadeite

从商贸实践角度出发,将翡翠中的包裹体定义为:翡翠中影响翡翠净度的结构性缺陷或内含物。翡翠的裂隙可以分为宏观裂隙和显微裂隙,翡翠中内含物主要是在成分和显微结构上造成影响净度的包裹体,并总结出翡翠内含物特征表。提出了翡翠分级的工具、背景、光源、范围。最后在前人基础上提出了划分翡翠净度分级方案。

In the angle of commercial practice, it defied the fluid inclusion of Jadeite： the structural defect or inclusion that influences jadeite clarity in the jadeite. The cranny of jadeite can be divided into macro - cracks and micro -cracks, inclusions of jadeite is inclusions which impact clarity mostly in the composition and microstructure, and summed up the characteristics of inclusions jadeite Table. Put forward the tool for grading, background, source and scope. Finally, based on the previous study, the program about jadeite clarity is carried out. grading of
