The tourmaline ring is not limited to decorative effects, but also has valuable accessories for value preservation. As a mosaic of tourmalines, they often have high-grade quality, even reaching the gem level, which is denominated in carats. As we all know, the greater the value of tourmaline is, the greater the value of the value-for-money appreciation. The finished tourmaline ring on the market usually takes the civilian route and is mainly decorated. If the inlaid tourmaline crystal is small, the potential for value-added preservation will be very low, so if you want to have a value of the tourmaline value that can be preserved, the best way is to buy the jewelry store and make the mosaic after you purchase the tourmaline. It is possible to determine the style of the ring by itself, and after the final production, the price is likely to be lower than the purchase of the same quality finished tourmaline ring. Save money and buy good goods, why not? Choosing a good tourmaline ring is not an easy task, similar to identifying ruby: a high-end tourmaline ring is rated 4C and 1T: color, clarity, cut ( Cut), carat weight, transparency. (1) color The price of tourmaline is mainly limited by color. In the international market, the price of blue and bright red tourmaline is the highest, and the red and green two-color and rose-red, emerald green tourmaline is also very popular in the market, and the price is higher. When choosing the tourmaline face, the color is even and beautiful; the two-color tourmaline or multi-color tourmaline, and the inner-infrared green watermelon tourmaline are also more precious and have collectible value; in addition, the tourmaline cat eye belongs to the top grade in the tourmaline. (2) Clarity The nature of the tourmaline is brittle and prone to cracks. At the same time, the interior contains a large number of inclusions. The presence of a large number of cracks and inclusions will affect the transparency, color and fire of the tourmaline. The inner pure tourmaline is also rare and belongs to the top grade. The business of the tourmaline itself has already chosen the crystal, but it is also exempt from a little embarrassment. Even a little bit of 瑕疵 has a great influence on the value of the tourmaline. Therefore, when selecting, try to select the inside of the crystal under the strong light without visible sputum. (3) The cut of the cut-behind tourmaline refers to the accuracy of its cutting ratio and the perfection of the finish after finishing. The shape design of tourmaline must firstly maintain the weight of the original stone according to the cleavage, quality and weight of the original stone, and dissect the original stone structure in the best state; and ensure the restoration of the color after the tourmaline is cut, showing the most beautiful Color, and then use the best method to deal with the original stone 瑕疵, to design the best tourmaline shape. For example, it is very important how some catfish with cat-eye effects make it fully express its special effects. The cutting of the tourmaline ring is usually made of super-fine diamond cutting method. After perfect cutting, it shows the brightness and fire of the tourmaline. (4) carat weight The weight of the tourmaline ring 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. (5) Transparency Bismuth ring is a high-end tourmaline, especially 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. Some of the tourmaline pendants, bead strings and engravings have more internal ice cracks and poor permeability. The merchants will increase the transparency through the injection molding process to cover up some cracks and impurities! High-quality tourmaline will not go to the glue injection process, so generally do not worry about the phenomenon of injection of glue on the tourmaline ring, but those with lower prices are likely to be glued!
