The reason why Tourmaline rose 5 times in 3 years

The price of a mid-range tourmaline bracelet two years ago was only more than 1,000 yuan in the Guangdi Jewellery Company of the Guangdong Geological Bureau. It has now risen to nearly 4,000 yuan. Once unfamiliar, willing to be emerald, diamond-lined tourmaline, with the public's constant understanding of colored gemstones, the price in the last five years rose at least 8 times, became a diamond, jade, Hetian jade, jewelry investment collection after another Focus on varieties.

The color of tourmaline is the most abundant In recent years, the price of tourmaline has risen dramatically. Why do people suddenly have so much interest in this colored gem?

Hu Xuenian, (registered jewellery inspector, registered jewellery appraiser, senior engineer of Guangdi jewellery company, Guangdong Provincial Bureau of Geology): Tourmaline is a tourmaline and its main ingredient is boroaluminosilicate. We say that it is a "brilliant tourmaline." On the one hand, it means that tourmalines are columnar crystals. The cylinders have vertical stripes. The cross-sections of the crystals are arc-shaped triangles. On the other hand, they refer to the "horses of its price." "Since the beginning," its price has been rising in recent years, and has risen at least 8 times in five years.

The reason why the tourmaline is popular is that, in the Guangdong area, the "Baiyan" and the "evil spirit" have a homonym. Many people therefore believe that wearing such a gem can ward off evil spirits; secondly, compared to other precious stones such as diamonds, red sapphire, and emeralds, tourmaline's "The tallest" is bigger and more beautiful. Third, the color of tourmalines is the most colorful of all gems. This is one of the reasons why it is popular and has a fast price increase. Pink, purple, brown, etc., in addition to green, blue, black, colorless and so on. In addition, the tourmaline also has the characteristics of polychromism. Observing the tourmaline in different directions will have differences in shades or shades. The effect will be more pronounced with the help of professional instruments.

The blue tourmaline, the most expensive tourmaline, can fire up, more or less related to the story of Cixi. Cixi is said to have a pair of watermelon tourmalines, tribute by Fanbang, worth 5 million two silver, has been placed in a jewelry room in the Summer Palace, by a group of three pro-trust eunuchs in turn to watch. Is this watermelon tourmaline the most expensive type of tourmaline?

Hu Xuenian: Similar to the 4C standard of diamonds, tourmaline mainly evaluates the quality in terms of weight, color, clarity and cut. The weight is naturally the heavier the better, and the color is even and pure. When other qualities (weight, clarity and cut) are the same, the blue tourmaline is the most expensive, red is the second, again Green. For example, in the head office of Guangdi Jewellery Co., Ltd. of the Geological Bureau of Guangdong Province, the price of the 14.84ct blue tourmaline pendant is 179,200 yuan, and the 13.66ct red tourmaline ring price is 112,560 yuan, all of which belong to collectible grade tourmaline. The name of the watermelon tourmaline is because it is red in the middle of the cross section, surrounded by green, just like the watermelon with red skin, the current market price of tourmaline is also higher; and in terms of clarity, the cleaner the tourmaline, the more Well, no cracks, no inclusions are the best. In addition, the finer the cut, the better.

Brassica's main producing areas are Brazil, Sri Lanka, Russia, and the United States. The most famous "Palaiba Tourmaline" comes from Brazil. It has a unique neon blue, electro-optical blue and other colors, and the fire color is also higher than other tourmaline. Due to the difficulty in mining the Paraiba tourmaline and the small crystal size, coupled with unclear mineral rights and disputes in recent years, the price has remained high and the retail price can reach 20,000 U.S. dollars. It is now almost impossible to see the market. , is an absolute collection level. In China, tourmaline's main producing areas are Xinjiang, Yunnan, Inner Mongolia, etc. Xinjiang's tourmaline granules are large, and the variety and quality are very good.

Can filled tourmaline be bought?

Because people do not have a deep understanding of the tourmaline, the percentage of false testers is quite high. Many of them are tourmaline coaches. Is this tourmaline potential for appreciation?

Hu Xuenian: Natural tourmaline most of the existence of different degrees of cracks, often used to make ring. The necklaces and bracelets that are generally sold in the market are all cracked. This is the structural feature of the tourmaline, but it affects the beauty and durability of the tourmaline. Because the tourmaline is easily cracked and broken during processing, in order to increase the production rate and improve the beauty and durability of the tourmaline, the fissures in the tourmaline raw materials are generally filled and consolidated prior to processing. Avoid raw material cracking. Therefore, there are more or less full-filled tourmalines on the market, but high-quality tourmalines, such as the abstaining class, are basically not filled. For the phenomenon of tourmaline filling, neither "stick kill" nor "let alone" is desirable. It should be treated differently depending on the degree of filling. For the tourmaline with a relatively large filling level, the testing organization should indicate "filling tourmaline" on the certificate. Clearly tell consumers.
