Many friends often do not know the red tourmaline and ruby, because these two gems are red, the color is very close under natural light, almost can not be judged with the naked eye. Many unscrupulous traders use red tourmaline jewelry to pretend to be ruby ​​jewelry, and consumers should pay attention when purchasing. Below, the Breguet classroom teaches you to identify red tourmalines and rubies. The easiest way Observed under the illumination of the UV light of the banknote, because most of the ruby ​​is strongly fluorescent, the ruby ​​is ruby, and the non-fluorescent is tourmaline. 2. Look at the color Ruby and tourmaline colors are very similar, and it is more difficult to distinguish. The color of the pigeons is vivid, but most of the rubies do not reach that feeling. They are all lighter and have a little powder. In contrast, the color range of the tourmaline is very broad, the color is fresh, from shallow to deep. 3. Look at the hue Ruby is chrome-to-colored, and in general, brown tones are rarely seen; most of the tourmalines can be seen in brown tones. 4. Look at the gloss Ruby has a higher refractive index than tourmaline, and its outer gloss is ruthenium, while tourmaline exhibits glass luster. 5. Look at cracks and inclusions Ruby interiors are common in crystals, melts, fluids, and fingerprint inclusions, so they affect the brilliance and transparency of the gemstone. In addition, ruby ​​crack development is more, so there is a saying of "ten red nine cracks". The common tubular fibers inside the tourmaline also have cracks but are not dissociated. In addition, the most common ruby ​​is that the rutile inclusions are clearly arranged at an angle of 60 and 120 degrees, but this is to be seen with a magnifying glass. 6. Look at the density Rubies are denser than tourmalines, so rubies of the same size are heavier than red tourers. To put it another way, it means that the same carat number of tourmaline is larger than ruby. 7. Measuring hardness The hardness under test can also be distinguished, the ruby ​​hardness is 9; the tourmaline is 7-8. However, the hardness test is a damage test, which is generally not very advocated.
