Journal: Identification and Appreciation to Cultural Relics

Keyword:  秋葵黄黄至黄闪鸡蛋黄;
Abstract: <正>和田黄玉产于新疆昆仑山、阿尔金山一带的且末地区,极为稀少,产出块度也较小,和田黄玉主要有淡黄、甘黄至黄闪绿色。黄玉的颜色一般比较淡,黄色鲜艳,浓艳的极为罕见,优质黄玉价值高于羊脂白玉。黄玉基质为白玉,因长期受地表水中氧化铁渗滤在缝隙中形成黄色调。根据色度变化定名为:密蜡黄、栗色黄、秋葵黄、黄花黄、鸡蛋黄等。古人以"黄侔蒸梨"者为最好。色度浓重的密蜡黄、栗色黄极罕见,其经济价值可抵羊脂白玉。在清代,由于黄玉为"皇"谐音,又极稀少,一度经济价值超过羊脂白玉。
