| 摘 要： | 翡翠的矿物组成、岩石类型不同，将会对翡翠的比重、折射率产生直接的影响。从翡翠的岩石学、矿物学角度出发，讨论了翡翠的岩石类型，依据组成翡翠的主要矿物的比重和折射率值，建立了翡翠矿物组成成分及含量与其比重、折射率关系图解，确定了各种翡翠的比重、折射率变化范围分别为：2．93～3．60和1．593～1．750；优质翡翠的比重、折射率分别为：3．178-3．240和1．644～1．657．为翡翠的质量评估提供了客观依据。

| Abstract: | The contents of jadeite's mineral composition and rock types will influence the refractivity and specific density of jadeite directly. On the basis of the study on the mineral composition and rock types of jadeite,the authors determine that the specific density and refractivity of jadeite ranges from 2.93 to 3.60 and from 1.593 to 1.750 respectively, the specific density and refractivity of jadeite with high quality ranges from 3.178 to 3.240 and from 1.644 to 1.657 respectively, and offers the objective basis for jadeite's quality appraisal,through setting up several charts of the relation between jadeite's specific density refractivity and its mineral composition. |
