对多种彩色珍珠样品进行了可见光光谱和拉曼光谱测试，研究了珍珠致色成分的种类及其与颜色的关系。研究结果表明：（1）彩色淡水珍珠和海水珍珠样品均会在1121～1132和1506～1524cm-1范围出现强峰，该特征峰归属于多烯化合物的C-C和C=C伸缩振动；（2）随着珍珠颜色的加深，样品位于1117～1132，1502～1524和2000～3500cm-1范围的峰逐渐增强，特征峰所代表的有机质与珍珠颜色有关；（3）深紫色淡水珍珠和深橘红色海水珍珠样品在1475～1575cm-1范围的包络峰可分成8～10个次级峰，计算可知多烯化合物C=C双键数目分别为N＝9～27和N＝7～27。珍珠中不同种类和含量的多烯化合物，可能是彩色珍珠的致色原因。

Based on the visible spectra and Raman spectra test of a variety of colored pearls samples to study the relationship be-tween the organic component and the pearl’s color was studied .The study results show that both the freshwater and seawater pearls exhibit strong characteristic peaks in 1 121~1 132 and 1 506~1 524 cm-1 range ,which is respectively attributed to the C-C and C=C stretching vibration ;the peak intensity in 1 117~1 132 ,1 502~1 524 and 2 000~3 500 cm -1 range increases as the color deepens ,which is closely related to the pearl’s color ;The peak in the 1 475~1 575 cm-1 range is divided into 8~10 secondary peaks of purple freshwater pearl and deep orange seawater pearl .The number of C=C double bonds is N=9~27 and N=7~27 respectively after calculation .Polyene compound of different varieties and content could be the reason for the pearls’ color .
