Tourmaline, also known as tourmaline, is a common jade variety on the market now. With complex components and rich colors, it is deeply loved by people because of its changeable colors and unique functions, and at the same time, it is a high-grade gem with high transparency. The color of tourmaline is complex and changeable, including pink, blue, green, yellow, black, brown and colorless. Among them, bright blue, bright rose red, pink and green are the top grades.

Tourmaline is one of colored gems after diamonds, rubies, sapphires and emeralds. The brighter the color, the higher the value. Can be made into various jewelry and handicrafts, such as tourmaline bracelets, tourmaline rings, tourmaline pendants and so on.

Method for identifying authenticity of tourmaline:

1, depending on the characteristics

Tourmaline is a kind of tourmaline. After being heated, rubbed or irradiated by the sun, its surface can release charges and has the characteristics of adsorbing dust and paper scraps. If this feature is used to identify, this phenomenon does not appear, indicating that it belongs to the imitation of tourmaline.

2. Transparency

Most natural tourmalines have some impurities, which look foggy and not completely transparent. Only the rare best tourmaline will be completely transparent. If the tourmaline is transparent and fog-free, it is either the best or an imitation.

3. Birefringence

Looking at the gem's watch under a magnifying glass, we can find that there is obvious double shadow on the bottom of tourmaline. Accordingly, tourmaline can be distinguished from pato stone of any color, and tourmaline without birefringence is an imitation.
