Natural tourmaline belongs to tourmaline, which gives off a weak current. It is still difficult to make imitations. It is enough to see if there is current when the two are rubbed when buying.

Natural tourmaline is rich in color and high in light transmittance. When the tourmaline line is illuminated with light, other colors will appear. However, the fake tourmaline has a low light transmittance, so it generally looks very black.

You can also watch the texture of tourmaline and observe tourmaline with strong light. There are many natural inclusions and cracks in tourmaline. Under a magnifying glass, the better the quality, the less cracks and inclusions. False inclusions will appear unnatural.
Tourmaline maintenance method
The first trick is to put tourmaline jewelry alone in the jewelry box when you don't wear tourmaline jewelry at ordinary times, so as to avoid the friction and collision between tourmaline jewelry and other jewelry, causing unnecessary losses.
The second measure, tourmaline hardness is 7-8, which is relatively high, but tourmaline itself is brittle and afraid of breaking. Unless it is pure and flawless tourmaline, try not to wear tourmaline stones for strenuous exercise or heavy work, so as not to cause tourmaline stones to break.
Third, it is a good habit to check and repair your jewelry regularly. Go to a professional jewelry store to check your tourmaline jewelry every month. If the gemstone falls off and is scratched, solve it in time.
