The occurrence of natural ruby and sapphire are relatively at a small amount, therefore, they have been considered as the precious ornaments cherished by the people. However, in the natural world, the minerals similar to the ruby and sapphire are at a big amount and even there exsit various kinds of artificial gems at present time.In order to tell the true from the false,the best from the poor,different physical methods and mineral crystal analysis have been adopted to discriminate their hardness, density and refraction etc..
