摘　　要：钻石的光学效果包括亮度、火彩、闪烁等,借助观察仪器能直观反映钻石美丽璀璨的外观。在过去四十年内,大量公司和机构研制出了用于观察和拍摄钻石光学效果的仪器设备,并制定了评判钻石光学效果优劣的方法。较早的设备是通过观察钻石的彩色图案分布判断钻石的切工,其采用了彩色宽泛角度范围的环形光源结构,例如日本的FireScope、八箭八心观察仪和美国宝石协会(AGS)研制的ASET观察仪等。为了更大程度展现钻石的火彩和闪烁效果,光源结构较为复杂的设备采用了LED灯作为照明装置,包括戴比尔斯公司的IRIS装置、捷迈克斯的Brilliance Scope、Sarine公司的Diamond Integrator以及中国地质大学(武汉)珠宝学院刘萍萍博士的钻石光学效果观察仪、作者的钻石身份鉴定仪等。各机构分析钻石光学效果的方法是以色度学理论为基础,使用机器视觉技术对所采集图像进行数字化分析。钻石光学效果观测仪正朝着更美丽、更生动、更科学准确分析的趋势发展,钻石光学效果可以作为对传统钻石4C分级的有力补充,成为第5个C,从璀璨度(Cui can)的角度,对钻石实际光学效果的表现进行评价。The optical effects of diamonds include brightness,fire,and scintillation.The beautiful and bright appearance of diamonds can be intuitively reflected with the help of observation instruments.Over the past four decades,a large number of companies and institutions have developed instruments and equipment for observing and photographing the optical effects of diamonds,and developed methods for evaluating the optical effects of diamonds.Earlier equipment judged the cut of a diamond by observing its color pattern distribution,which used a ring-shaped light source structure with a wide range of colors,such as Japan's FireScope,Hearts&Arrows viewer and ASET observer from AGS.To display the fire and scintillation of diamonds to a greater extent,equipment with more complex light source structures uses LED lights as lighting devices,including De Beers'IRIS device,Gemex's Brilliance Scope,Sarine's Diamond Integrator and China Dr.Liu Pingping's diamond optical effect observer from the University of Geosciences(Wuhan).It also includes the author's diamond identification instrument.The method used by various institutions to analyze the optical effects of diamonds is based on colorimetry theory and uses machine vision technology to digitally analyze the collected images.Diamond optical effect observers are developing towards a trend of more beautiful,more vivid,more scientific and accurate analysis.Diamond optical effects can serve as a powerful supplement to the traditional 4C diamond grading and become the fifth C,starting from brilliance angle to evaluate the actual optical effect of the diamond.
