颜色 : 宝石的颜色取决于个人的喜好。铬和铁的含量产生了红

宝石颜色的差异,而蓝宝石的各种颜色变化主要取决于宝石当中

钛和铁的含量。不同的国家有不同的地质条件,每个国家的矿山

都不同,因此所产的红/蓝宝石颜色也各不相同。

Color is a matter of personal preference. Rubies vary in

color depending mainly upon their chromium and iron content,

whereas sapphires vary in color depending mainly upon their

titanium and iron content, Therefore ruby /sapphire from different

countries* and mines have different predominant color.
