| 摘 要： | 近年来彩色钻石（简称彩钻）在国际拍卖市场上的重要性越来越明显，统计、梳理和定量分析近十年来苏富比、佳士得两大国际著名拍卖公司的彩钻拍卖记录，对研究彩钻价值的影响因素及其分级、价值评估具有十分重要的意义。研究结果显示，彩钻价格主要建立在颜色稀有程度及消费者偏爱之上，对价格影响最大的是其颜色色系、色彩瑰丽程度（饱和度、亮度和次要色调）；克拉单价通常与大小呈正比；净度、拍卖时间、来源（品牌）、类型等对其成交价格也有一定的影响。合成和经优化处理的彩钻可能会影响部分彩钻的价格，但总体上，其价格和天然彩钻价格之间没有发现必然联系。另外，高档彩钻在金融危机期间的表现显示其商品属性已从一般的奢侈消费品转变为资产投资品。上述结果说明，色彩、饱和度、亮度和次要色调是影响彩钻品质最重要的因素，就此而言，我国可参考美国GIA彩钻分级体系和澳大利亚力拓集团粉红色钻石的分级体系来建立适合中国市场的彩钻分级标准。

| Abstract: | Coloured diamonds play an increasingly important role in the jewelry family in recent years. In order to have a better understanding of pricing factors, criteria of rating and evaluation of coloured diamonds, the authors collected and analyzed the auction information of coloured diamonds from Sotheby and Christie in the last 10 years. Research results show that the prices of coloured diamonds are mainly based on the rarity and the consumer＇s preference of colour. And colour group, saturation, brightness as well as sub-group of colour also in- fluence the prices greatly. Price per.carat of coloured diamonds usually is in a direct ratio to their carat weights. Clarity, auction time, sources or brands, diamond type also affect the transaction prices. Although synthetic and improved coloured diamonds may affect the prices sometimes, no direct connections are found between their prices and the natural ones. Besides, it seems that superior coloured diamonds have changed from luxury goods to assets and investments during the financial crisis. In conclusion, colour is the most important pricing factor of coloured diamonds. Therefore we can refer to the coloured diamonds＇ grading system of GIA and the pink diamonds＇ grading system of Rio Tinto Group when establishing the coloured diamonds＇ grading standard suitable for Chinese market. |
