Tourmaline is borosilicate crystal. Tourmaline is a borosilicate crystal, also known as tourmaline. Tourmaline has complex components and diverse colors. The international jewelry industry basically divides commercial varieties according to the different colors of tourmaline. The darker the tourmaline color, the higher its value, such as rose red, watermelon red and blue. Tourmaline is in a crystalline state with high hardness and humidity. The less impurities, the more crystal clear and the higher the value.
When the surface of real tourmaline is heated, it will produce electric ions. You can put tourmaline on clothes and rub it repeatedly to make it hot. Then, put tourmaline near the scraps of paper to see if the surface of tourmaline can absorb scraps of paper. There are many inclusions in natural tourmaline. There are two kinds of tourmaline inclusions, one is balloon-shaped gas-liquid inclusions, and the other is needle-shaped and thin tubular inclusions.
Tourmaline has high hardness and brittleness. When tourmaline and other ornaments are put together, scratches or collisions will occur, leading to other cracks. Therefore, it is recommended to keep tourmaline separately after wearing it. Wearing tourmaline for a long time will accumulate dust and grease on the surface. It is recommended to soak in warm water for more than ten minutes, and then wipe the surface with clean cotton cloth. Tourmaline is an energy gem. It is recommended to wear it every month and put it in a crystal for degaussing.
