Identification of Sapphire

time：2023-10-11 source：sznbone Views：





The color of natural sapphires is often uneven, with most having straight growth patterns. Artificial sapphires have the same color, and their growth patterns are arc-shaped, often with bread crumbs or bead like bubbles visible inside the body.




Natural sapphire also has obvious dichroism, appearing blue from one direction and blue-green from the other. The coloration of other gemstones is different from that of natural sapphires, and can be distinguished based on this.




In addition, the simplest method can be hardness measurement. Natural sapphire can carve marks on topaz, while other blue gemstones are difficult to carve marks on topaz. Therefore, when purchasing jewelry, if there is no instrument nearby, as long as there is a piece of topaz, sometimes it can also solve some problems.
