国际拍卖市场粉钻价格影响因素浅析

Influence Factors of Price of Pink Diamond Sold in the International Auction Market

粉钻作为彩色宝石中的重要品种,近年来受到市场广泛地关注和欢迎。通过整理和统计1998年至2012年期间苏富比与佳士得两大拍卖行在全球范围内的粉钻拍卖记录,对粉钻价格的影响因素进行了分析。研究结果显示,不同颜色等级会导致十分大的价格差异,其中饱和度和明度是影响粉钻价格的重要因素,次要色调会降低粉钻的克拉价格;同时,克拉价格整体上与粉钻克拉重量呈正比趋势,但两者之间并非简单的线性关系;此外,净度等级、拍卖时间以及粉钻出身(品牌、设计师、历史等)及是否为Ⅱa型钻石对粉钻价格也有一定程度的影响。

Pink diamond attracts much market concern and it is increasingly popular as an im- portant type of coloured diamonds in recent years. In order to analyze the influence factors of price of pink diamond, the authors collected and tabulated the worldwide auction data of pink diamonds from Sotheby＇s and Christie＇s during the period of 1998 to 2012. Research results show that pink diamonds with different colour grades could be sold at significantly different prices. Saturation and brightness affect the price of pink diamond greatly, and the price could be reduced by all kinds of modifying colours. Prices per carat trend to be in proportion to the carat weight of pink diamonds on the whole, but they are not simply linear relation- ship. Other factors such as clarity grade, predigree （brand, designer, history and so on） and diamond type （type Ⅱa or not） would affect the price of pink diamond partly.
