摘　　要：针对我国珍珠分级国标无法定量化确定珍珠总质量级别而难以在市场广泛应用的问题,以淡水无核养殖珍珠链为例,通过市场调查收集我国淡水珍珠价格信息,分析颜色、光泽、大小、光洁度、形状等各品质因素对淡水珍珠价格影响的权重,确定了权重系数;利用权重法、光泽主导法两种方法确定了样品珍珠的总质量级别。结果表明,以权重法为基础确定了三个主要质量因素的影响系数,具有一定的参考意义。但因无法在市场上收集到所有影响淡水珍珠质量因素的级别资料,难以准确量化分析,确定的权重难免存在误差;以光泽为基础确定总质量级别,依赖于权重和有色宝石的标准,存在一定的不确定性;切实落实我国国家标准在市场中的应用还需要不断的考察研究。Chinese national standard on cultured pearls can’t stand for the method and standard of the total quality of jewelry pearls,which limits its application in the market.This paper takes Chinese freshwater non-nucleus cultured pearl chains as examples,use the market survey to collect freshwater pearl price information in China,analyzes quality factors including colour,luster,size,finish,and shape,make sure each quality factor’s weight that impacts the price of freshwater pearls,and determine the weight coefficient.The total quality level of the pearl samples was determined by weight method and luster dominant method.The results show that based on the weight method,the influence coefficients of the three main quality factors are determined,which is of certain reference significance.However,due to the inability to collect all grade data of factors that affect the quality of freshwater pearls in the market,it is difficult to make accurate quantitative analysis,and it is inevitable to have errors in the weight determination.Determine the total quality level based on luster,depending on the weight and the standard of coloured gemstones,is not scientific enough,and the practical implementation of Chinese national standards in the application of the market also needs constant investigation and study.
