    • An apparatus for measuring the color of a brilliant-cut diamond, comprising a light source for providing a measuring light, a holder for holding the diamond to allow the measuring light to enter the diamond through a table facet thereof, a photodetector for detecting a light which has emerged from the diamond through its table facet, a measurement unit for measuring a spectrum of the detected light and an arithmetic unit for deriving tristimulus values from the spectrum.The apparatus is of great practical advantage in that it can objectively measure the colors of brilliant-cut diamonds, and can produce measured outputs which can easily be converted to color grades of the type which has widely been used conventionally.
    • 一种用于测量切割金刚石的颜色的装置,包括用于提供测量光的光源,用于保持金刚石的保持器,以允许测量光通过其台面进入金刚石;光检测器,用于检测光 其通过其表面从钻石出现,用于测量检测到的光的光谱的测量单元和用于从光谱导出三刺激值的算术单元。 该装置具有很大的实际优点,可以客观地测量辉光切割钻石的颜色,并且可以产生可以容易地转换成常规使用的类型的颜色等级的测量输出。
