Red Tourmaline is pink, pink, rose, dark red, purple and other red-key tourmaline. In mineralogy it is mainly a kind of tourmaline. Red tourmalines are similar to other red gemstones in color and ruby, but they are not rubies after all. How do you distinguish rubies from other red gemstones? (For more information, please pay attention to China Crystal Industry Network) The difference between ruby ​​and other red gemstones depends on hardness testing. Because the ruby's hardness is 8.8 to 9 on the Mohs, the hardness of other possible alternatives is lower than it. For finished products that have been polished, it can be used to sculpt top hardness plates such as topaz, crystal, etc. to determine the hardness. According to the hardness, it can be roughly confirmed whether it is ruby. In addition, according to the ruby ​​hue is also distinguishing red tourmaline and other red gems to distinguish one feature. One of the methods, measuring its refractive index, is similar to that of ruby. The garnet-like Mg-Al has a refractive index between 1.74 and 1.75, which is lower than that of ruby. The red tourmaline has a refractive index between 1.624 and 1.644. Sometimes iron-aluminum-magnesium garnets may be mixed with rubies from Thailand, but the colors are very different. In the second method, except for artificial ruby ​​and red tourmaline, all other red varieties have no dichroism. Red tourmaline's dichroism is similar to that of ruby, but under the Chelsea filter, the red tourmaline does not show red fluorescence (note that very few red tourmaline reds are caused by the chromium-containing elements, and fluorescent reactions are seen under the filters. But can be distinguished from the hardness). The two-story stone is not difficult to distinguish as long as it is carefully observed. That is, the accessories are removed from the tray and placed in a bottle filled with water. The waist of the gemstone is carefully observed. Since the two-layer stone is a mixture of two red varieties, the color is very different and it is easy to see in the water. In addition, observation of the waist with a 10x magnifier revealed bubbles in the bonding line and the bonding site. Another reliable method is to measure the refractive index of the upper and lower layers. The difference is a two-layer stone.
