How to choose the best tourmaline The tourmaline is very rich in color and has a high hardness, but it has a relatively brittle character. In the process of purchasing tourmaline, we mainly start from the three aspects of transparency, color and purity of tourmaline. (1) Transparency of tourmaline The crystallized and clearer the crystal, the better the quality of the tourmaline. If there is obvious fog and opacity, the relative quality is poor. Usually, the opaque scraps will be ground into beads to make bracelets or necklaces. The price is cheap and the collection value is not very high. (2) The color of the tourmaline Tourmaline can be divided into red tourmaline, green tourmaline, azure tourmaline, black tourmaline, purple tourmaline, colorless tourmaline, bicolor tourmaline, watermelon tourmaline, cat eye tourmaline, sodium magnesium tourmaline, Alexander color tourmaline, calcium lithium tourmaline, chrome tourmaline and para There are 14 kinds of Ibashi and other kinds. Among them, red, blue and green are more expensive, and among them, the color is gorgeous and the fire is outstanding. Also more valuable are the two-color tourmaline and multi-color tourmaline, the tourmaline cat eye belongs to the top grade in the tourmaline. (3) The purity of tourmaline Tourmaline has more brittle characteristics, it is more prone to cracks, and the interior will contain a large number of inclusions. The presence of a large number of cracks and inclusions will affect the transparency and color of the tourmaline. Of course, the inner pure tourmaline is called the vitreous. Very rare, belonging to the top collection. Purchase considerations 1. As a collection or have an appreciation requirement, the top quality and rare gems will be safer and faster. In general, the top tourmaline above 10 carats guarantees its rarity. 2. In terms of color, if it is green tourmaline, it is best to choose transparent grass green or blue-green, because the green tourmaline color will be black when it is too dark, affecting the beauty and transparency of the gemstone; red tourmaline must choose very positive Red, the price of red tourmaline with a little yellow, brown or light pink will be much worse; blue tourmaline itself is very rare, the price is much higher than other tourmaline species, if you buy a blue tourmaline above 10 carats, certainly not I am worried about how to shoot in the future; as for the Paraiba Tourmaline, it is not necessary to say that if the financial resources can be achieved, then there should be no hesitation, because Paraiba is the price increase every day, and it is also likely to disappear at any time. Priceless treasure. At present, a 10-carat tourmaline gemstone is about RMB 50,000-200,000 depending on the price of the color (except Paraiba). Basically only equivalent to one carat of diamonds of the same grade. This is of course related to the reasons for the short history of the tourmaline and the low market acceptance. But it is worth noting that the tourmaline deposits are much faster than diamonds. In other words, the rareness of the tourmaline will surpass the diamond in the short time to come. In fact, in the field of gemstones, there are more than one type of gemstone that exceeds the price of diamonds due to its scarcity, the most famous of which is emerald. In the middle of the 20th century, the price of emeralds soared at a rocket-like speed. Until now, it has become a regular auction of major auction events. The price of emeralds of the same size has surpassed diamonds. SHAOXING CLOTHO APPAREL CO.,LTD , https://www.clothoapparel.com
