摘要
我国东部蓝宝石为岩浆型原生矿床及与之有关的残坡积、冲积砂矿．对各矿区蓝宝石的宝石学研究表明，蓝宝石普遍特征是颜色较暗、透明度差，色彩鲜艳程度低，严重地影响了宝石的质量和经济价值．
The sapphire in eastern China comes from the primary magmatic deposits and the related residual and alluvial placer. The gemological study on the sapphires from different mining areas shows that the sapphire is generally characterized by dark colour, low transparency and low colour brightness, seriously affecting the quality and economic value of the sapphires.
