Natural sapphire has obvious dichroism

Natural sapphires tend to be uneven in color, and most have flat growth patterns. The artificial sapphire has the same color, and its growth pattern is a curved belt, which often shows crumb-like or bead-like bubbles in the body.

Natural sapphire

Natural sapphire also has a distinct dichroism, which is blue in one direction and blue-green in the other. The coloration of other gemstones is different from that of natural sapphires and can be distinguished accordingly.

In addition, the easiest method is to use the hardness method. Natural sapphire can mark the topaz, while other blue stones are difficult to mark on the topaz. Therefore, when buying jewelry, if there is no instrument around, just have a piece of topaz. Sometimes it can solve some problems.
