The complexity of the chemical composition makes the chemical formula of tourmaline extremely complicated. Basically, tourmaline is a compound composed of a group of borate and silicate and a variety of metal elements. It is precisely because of its complex chemical composition that tourmaline will be diversified. Colors. Almost all the colors of colored gemstones, tourmaline has one type, and even a gem has two to three colors, ve daha.

Tourmaline is not only bright in color, but also has a strong enzyme pleochroism, so tourmaline crystals often show different colors when viewed from different directions. The crystal system of tourmaline is a trigonal crystal system, the crystals are mostly long columnar, viewed from the cross section as hexagonal or triangular columnar crystals, often co-existing with minerals such as quartz and beryl, with a hardness of 7, a refractive index of 1.615-1.655, double The refractive index difference is between 0.018 Ve 0.040, usually 0.020, and the specific gravity is between 3.00-3.26.

After the tourmaline is heated, the two ends of the crystal will have different positive and negative charges. This is the unique thermoelectric effect of tourmaline. People use this effect to remove soot. Only tourmaline of all gems has this effect. This is why tourmaline is called tourmaline in mineralogy.

Ek olarak, tourmaline has an effect called piezoelectric effect, also known as alternating current effect. When the two ends of the tourmaline are pressed, they will also show different charges. Among all gems, only quartz has the same piezoelectric effect. This effect of quartz stone is used in the watch industry, and these two effects of tourmaline can be used to measure the luminous intensity and pressure changes, and are widely used in the optical industry.

In short, the characteristics of tourmaline not only make her colorful, but also can be used in industrial production.
