What is tourmaline? Tourmaline, also known as tourmaline, is the English name Tourmaline. It is derived from the ancient Tunga Luo (Ceylon) word Turmani. It is the meaning of "mixed gemstone". Because its composition is complex silicate, its The hardness is 7.5, the specific gravity varies between 2.92 and 93, and the refractive index is between 1.6241 and 644. Under normal circumstances, the tourmaline raw material is long columnar, the column has longitudinal stripes, the cross section of the crystal is curved triangle, and the raw materials are easy to identify.

Tourmaline requires crystal clear, the more transparent the better the quality, do not have obvious fog or opacity, the higher the transparency, the higher the price.
Finally, the size of the tourmaline is also a very important factor to be referenced. The weight of tourmaline is calculated in carats. Under the condition that other conditions are similar, as the weight of tourmaline increases, its value increases geometrically; the tourmaline with the same weight will have a far-reaching value due to the difference in color, clarity and cut.
What is tourmaline? In the jewellery world, tourmaline is a medium-to-high-end gemstone, and high-quality tourmalines are rarer than diamonds.
