What are the identification methods of natural tourmaline and artificial tourmaline? Natural tourmaline has not undergone industrial processing, and its texture is natural and its color is pure and transparent. The artificially treated tourmaline will be filled with glue, and after being enlarged, the treated tourmaline will see the corrosion traces of spider webs, and the treated tourmaline is not tough enough, and the internal cleanliness is not good, which has the feeling of mixed glue!

Artificial tourmaline is mainly filled with glue.

And this kind of filling fraud mainly occurs on some rough tourmaline carvings and beads! This tourmaline has poor permeability and rough and loose texture due to ice cracks inside. It can be improved by injecting glue to cover up some cracks and impurities!

The treated tourmaline has enlarged friction on the surface, and there are also cobweb-like corrosion traces similar to jade B. Moreover, the treated tourmaline is not bright enough, and its internal cleanliness is not good, which has the feeling of mixed colloid!

One more thing, if it is tourmaline cut stone, then the brightness of tourmaline treated with glue on the reflective surface is not as good as that of natural tourmaline bare stone. Because of its good permeability and internal structure, the cut tourmaline is generally a high-quality natural tourmaline bare stone, with no impurities and cracks in its body and high transparency.

If the tourmaline bare stone you see has these characteristics, generally speaking, it will not be treated.

Tourmaline can be distinguished by its characteristics, such as its pyroelectricity. According to the pyroelectricity of tourmaline, rubbing tourmaline will produce electrostatic field to suck away the dust around it and darken it, so the real tourmaline will darken. If the tourmaline doesn't darken after rubbing it, it means it's fake. In addition, the commonly used fake tourmaline is a glass imitation. You can observe whether there are small round bubbles in tourmaline. If there is a round bubble, it means that it is a glass product and a fake tourmaline.
