The tourmaline homophonic "dispels evil spirits", as the leader of domestic colored gemstones, has been leaping from 2006 to now. Nowadays, it has become a household name. In the long run, its growth momentum will continue to be maintained, but I think it will be relatively moderate and stable.
Tourmaline is the most colorful colored gemstone. What kind of tourmaline can be purchased to achieve both the value of wearing and the value of collection. Today, I can share some of my insights.
1, Paraiba Tourmaline ★★★★★
Speaking of the varieties of tourmaline, we have to first mention the king of the tourmaline, "Palaiba," which was first discovered in the province of Paraiba in northeastern Brazil, followed by Mozambique and Nigeria.
It is made of copper and manganese to give it a stunning blue color, and its output is only one-thousandth of a diamond, and the large carat of Paraiba tourmaline is even rarer.
Because of the high price of this tourmaline, the price of high-quality Paraiba blue tourmaline is about 20,000 US dollars per carat, and there are more imitations on the market. Therefore, you must choose the internationally authoritative color gem identification certificate when purchasing: Gubelin (Gublin Gem Laboratory), GRS (Swiss Gem Laboratory)

Since tourmaline is a gemstone with positive and negative ions, it tends to show the same color of the same gemstone crystal. Among them, the red and green watermelon tourmaline is the most precious and rare. It was very popular in the Empress Dowager Cixi in the Qing Dynasty. Watermelon tourmaline.
When choosing watermelon tourmaline, the color should be considered as the inviting factor. Bright red and green are the first choices, and the internal cleanliness should be taken into account. Because the tourmalines often have obvious inclusions inside, the choice is to be able to Considering.

The tourmaline covers the colorful colors, but the red tourmaline is the most precious, especially in the rich red (like the ruby ​​red), followed by purple red, pink, when choosing the red tourmaline, it is also the priority color, followed by the net Degree, the final comprehensive choice.

4, blue tourmaline ★ ★ ★ ★
The blue tourmaline is probably the rarest variety in the tourmaline, especially the pure blue tourmaline, which is bright and blue, comparable to the most beautiful sapphire. However, the pure blue tourmaline (Indicolite) is quite rare, and most of the blue tourmalines produced by nature are more or less green.
In the end, there are many customers who will buy the tourmaline carvings. I don't agree with it from my personal point of view. Because the tourmaline is different from jade, it is a gemstone crystal, and the tourmaline carvings are usually thinner and easier to break.
Secondly, the high-quality tourmaline will first cut the faceted gemstones, followed by the curved gemstones and bead strings, and finally the carvings. Therefore, from the perspective of collection, the carvings of the high-quality tourmaline crystals have the investment value.
