The contents of jadeite ' s mineral composition and rock types will influence the refractivity and specific density of jadeite directly
摘要翡翠的礦物組成、巖石類型不同，將會對翡翠的比重、折射率產生直接的影響。 -
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 jadeites quality appraisal, through setting up several charts of the relation between jadeite ' s specific density refractivity and its mineral composition
從翡翠的巖石學、礦物學角度出發，討論了翡翠的巖石類型，依據組成翡翠的主要礦物的比重和折射率值，建立了翡翠礦物組成成分及含量與其比重、折射率關系圖解，確定了各種翡翠的比重、折射率變化范圍分別為： 2 . 93 ~ 3 . 60和1 . 593 ~ 1 . 750 ；優質翡翠的比重、折射率分別為： 3 . 178 ~ 3 . 240和1 . 644 ~ 1 . 657 ，為翡翠的質量評估提供了客觀依據。
