摘　　要：分析了山东蓝宝石与世界及我国各产地蓝宝石的质量差异。指出山东蓝宝石是国内质量最高的蓝宝石,在世界所有玄武岩源岩类蓝宝石中占有重要地位,可与澳大利亚、柬埔寨、泰国蓝宝石媲美;文章还剖析了包裹体、色带、熔蚀构造、裂纹对蓝宝石质量的影响。发现这4种因素一方面可通过影响蓝宝石的颜色、透明度、形状、大小、出成率等降低蓝宝石的等级,另一方面在某些特殊条件下,又可形成星光蓝宝石、魔彩蓝宝石、花色蓝宝石等稀有珍贵品种。The quality differences of sapphires coming from Shandong and other places in China and the world are analyzed. Sapphires in Shandongare the best in quality in China and play an important role in all sapphires coming from basalt. Sapphires from Shandong have the same quality as the onesfrom Australia, Kampuchea and Thailand. The influence of inclusions, color zones, corrosion structures and fractures on the quality of sapphires is dis-cussed. The above four factors affect color, transparency, shape, size of sapphires, and reduce grade of sapphires. In some special conditions, the factorscan also form rare varieties such as star sapphires, fantasic - color sapphires, variegated sapphires, etc.
