In the colored gem world, the tourmaline is unique in its rich colors, and the color plays a decisive role in the value of the tourmaline. First of all, like diamonds, tourmaline also evaluates its overall quality in terms of color, clarity, cut, and carat weight. The most important factor is color. Whether the color of tourmaline is bright and natural, whether it is soft or not is very important. .
Because the color is close to ruby, the red treasure tourmaline is called red treasure tourmaline. The color ranges from purple red to rose red, pink to deep red. It is the most popular color in the tourmaline, and it is also a relatively high price, except for Paraiba. The value is far more than the other colors of the tourmaline. At present, a 10-carat tourmaline gemstone is priced at 50,000 to 150,000 yuan depending on the color. It is basically equivalent to a one-carat diamond of the same grade. Good quality red tourmaline requires bright colors, pure color, uniform distribution and bright luster. The color tones vary and the values ​​vary widely.
The inside of the tourmaline usually has more inclusions. It is more common in tubular inclusions and gas-liquid inclusions. The clearness of the tourmaline requires less internal inclusions, and the cleaner the price. But usually fish and bear's paw can't have both, the color and clean tourmaline is hard to find after all, but the choice of colored gemstones is still based on color.
Because the tourmaline is relatively fragile and has many inclusions, it is prone to cracks during the carving process, and it also has great requirements for cutting. It is tailored to cut, symmetrical, and polished. It can usually be cut into emerald, oval, round diamond and hybrid. Among them, the emerald type can best reflect the beautiful color of tourmaline, which is the most suitable type of cutting, but the emerald type has the highest requirements for the quality of the tourmaline stone, and the relative price is also higher, so the large tourmaline that can be formed is very rare. In the jewelry auction held in the past two years, in addition to the jade is still rising, the tourmaline began to emerge as an emerging gem, and the upward trend is obvious.
