For people who are now more and more focused on health, how can they better maintain their health? Many people say that they usually pay more attention to diet and exercise, but for fashion people, they are more than just the same in terms of health. They also have to pursue how to keep themselves closer to fashion while maintaining health. And more and more popular wearing tourmaline health has become the first choice for fashion women friends. But how do we identify the tourmaline? Below, we Shijingdao Crystal Caibao will share the three-step method for identifying tourmaline.
In normal times, we lack the identification of equipment, but we can still identify ourselves in the daily life. We usually identify the accessories of tourmaline based on the following three characteristics:
Tourmaline
First, tourmaline has strong dichroism, red tourmaline is red---pink; green tourmaline is green---light green. According to this, green tourmaline can be distinguished from olivine and green glass, green garnet and the like.
Secondly, the tourmaline has a large birefringence. When viewed from the stage, it can be seen that the ribs are obviously double-shadow, so that the tourmaline can be separated from the topaz and the synthetic spinel.
Third, the tourmaline is often ground into an emerald type. Some tubular wraps or cotton batt are often seen from the parallel long direction, and the color is often deepened when viewed in a short direction. This is because the tourmaline absorbs light in different directions. Different, this feature can be used to distinguish some synthetic imitations.
The key to the identification is that the long columnar and transverse sections of the tourmaline feature are arcuate triangles; often with obvious dichroism, visible double shadows. The price of tourmaline is mainly limited by its color. In the international market, the price of the bright red and bright blue tourmaline is the highest, and the red and green two-color and rose-red, emerald green tourmaline is also very popular in the market, and the price is higher.
