There is a lot of color in the tourmaline, and the red tourmaline is the leader among them. Its color is mainly from pink to deep red. When the tourmaline is close to bright red, it will be very similar to the color of ruby. What is the difference between tourmaline and ruby? There is a very simple way to distinguish between them: the fire reflected inside the ruby ​​is bright red, and the tourmaline is red with a pink hue.
The simplest method of identification is to observe the gemstone under the illumination of the UV light of the banknote, the ruby ​​is the fluorescent, and the red tourmaline without the fluorescence. Secondly, although the colors of the two are close, the difference in the color of the two gems can be seen by careful observation. The most precious ruby ​​is the pigeon blood red, the pigeon blood red color is bright red, most of the red tourmaline does not have this difference. Moreover, it is also possible to distinguish rubies by observing the color of the gems. In general, it is rare to see rubies in brown tones; and most of the tourmalines can be seen in brown tones. Ruby has a higher refractive index than tourmaline, and its outer gloss is ruthenium, while tourmaline exhibits glass luster.
Of course, you can also distinguish the two gems by the density and hardness of the gems. Regardless of the density and hardness, the rubies are stronger than the tourmaline, so you only need to distinguish the two gems by the details.
