How to identify natural tourmaline

How to identify natural tourmaline? In the jewellery world, tourmaline is a medium-to-high-end gemstone, and high-quality tourmalines are rarer than diamonds. At present, many unprofessional homes on the market sell some low-end tourmalines and crystals together, and tell customers that tourmaline is a kind of crystal, which makes many people think that tourmaline is a kind of crystal with low price. In fact, this is not true. Tourmaline and crystal are two different minerals. Let's take a look at how natural tourmaline is identified!

Tourmaline uses color, transparency, internal defects and weight as the basis for evaluation and purchase.

The transparency of the tourmaline is better, the surface has a glass luster, the same crystal color is uneven, the internal defects (inclusions and cracks) are less, the tourmaline is brittle, and care should be taken to avoid impact when wearing.

When the tourmaline is heated, rubbed or irradiated by the sun, its surface will carry a charge. These charges are attracted to the opposite charge in the air, and can absorb the dust and paper scraps in the air with opposite charges. Some characteristics.

The cut surface of the tourmaline gemstone is quite good because of its transparency and internal structure. Generally speaking, the high-quality natural tourmaline bare stone has almost no impurities and cracks in the naked eye, and its transparency is also very high! If you see the tourmaline bare stone has these characteristics, then in general it will not be processed!

True tourmaline often has obvious dichroism, visible double shadow; tubular wrap or cotton batt can be seen in the body, and the cross section of the crystal is curved triangle. These characteristics are not available in the imitation.

As the most colorful gemstone in the world, the tourmaline crystal has up to 15 colors, and the colors are colorless, rose red, pink, red, blue, green, yellow, brown and black. Among them, the transparent blue, fresh rose red and pink plus green color are the top grades.
