摘　　要：翡翠，从广义讲是指具有商业价值，达到宝石级的硬玉岩的商业名称，是各种颜色宝石级硬玉岩的总称；狭义的翡翠概念是单指那些绿色的宝石级硬玉岩。影响翡翠成品的商业等级评价的因素是：颜色、透明度（水）、纯净度、结构（种）、成品的形状、做工及重量。颜色是全面评价翡翠成品商业等级的第一因素或者是关键因素，颜色不纯正，其他因素再好也上不了档次。透明度和结构及纯净度有相关关系，所以透明度是评价翡翠的重要因素。抓住这两极主线，再结合考虑其它因素，对翡翠成品进行商业等级评价就会顺理成章。In sensu lato, feicui is a commercial name for jadaeitite with gem quality and commercial value, the general name of gem jadaitite with various colors. However, in sensu stricto, it only means the green jadaitite with gem quality. The factors affecting commercial class evalu ation of feicui product are color, transparence (watery), purity, texture (species), product form, processing and weight. And the color is the first or key factor in the comprehensive e valuation of commercial class of feicui product. If the color is not pure and correct, the prod uct cann,t be a high quality feicui even other factors are very good. The transparence is an im portant factor in the evaluation of feicui because it is related to the texture and purlty. Paying attention to these two main factors, in combination with consideration of others, the evalua tion of commercial class of feicui product will have reasonable results
