How to determine the color and value of tourmaline?

Tourmaline has the reputation of a kaleidoscope in gemstones, which can be seen in its rich colors, with red, yellow, blue, green, and black as the main combination of colors, including transparent and lustrous blue tourmaline, rubellite, watermelon tourmaline and green tourmaline as the top grade; Tourmaline is loved by people, especially women, because of its bright color, variability and high transparency. The international jewelry industry divides the grade of tourmaline by the color of tourmaline, and the color with the highest demand is pink, bright red and green, of which red and green tourmaline are the most common and popular, but only the color of medium and vivid depth is a good product, if the color is too dark or too light, the value will be greatly reduced, so what is the best color of tourmaline, the most expensive value? 1. Rubellite Tourmaline Rubellite is the highest value in tourmaline, the color is purple-red, rose-red is the best, if the color is deep, it is also called "double pink", and the light color is called "single pink" or "child face".

The good ones are like rubies; This is followed by pink and light red tourmaline. Second, green tourmaline green tourmaline, green tourmaline in the emerald is the best, in Europe and Brazil and other countries green tourmaline has been mistaken for emerald, which can be seen its preciousness, followed by yellow-green green tourmaline; 3. Blue tourmaline Blue tourmaline is very rare in pure blue, common dark blue or greenish blue, blue tourmaline is like sapphire as the top grade; Fourth, watermelon tourmaline Watermelon tourmaline is because tourmaline presents a complex of two colors or a variety of dyeing, this kind of tourmaline is very rare, like watermelon, this kind of tourmaline is also a relatively high value in tourmaline. 5. Yellow tourmaline Yellow tourmaline, pure yellow or orange tourmaline is difficult to see, different shades of yellow or brownish yellow are very popular, but yellow tourmaline is pure yellow tourmaline as the top grade, but it is rarely seen on the market.

In addition, in addition to the above colors of tourmaline is better, there is also a kind of tourmaline is the Paraiba tourmaline from Brazil, which is revered as the king of tourmaline because of its extremely rare production, very unique color, sparkling and transparent, and unique fluorescent effect. In the international market, the general bright red and bright blue tourmaline is the highest, and the red and green bicolor and rose red and emerald green tourmaline are also very popular in the market. In the selection of inlaid tourmaline jewelry, it is better to have a uniform and bright color; In necklaces and bracelets, it is better to have rich colors, and the color of each bead can be different, with red, yellow, blue, green, purple and other colors; Pandora is more abundant in color, and more valuable is that there are two or more colors on the same tourmaline, that is, bicolor tourmaline or multicolor tourmaline, and watermelon tourmaline with inner infrared green is also more precious; In addition, tourmaline cat's eye belongs to the top grade of tourmaline.

Generally look at the transparency and whether there are impurities.

Colourless. The least valuable color of tourmaline is colorless. The color of tourmaline can be divided into several categories, such as blue, red, green, brown, colorless, and multicolored.

Only vivid colors with medium depth are good, and if they are too dark or too light, their value will be greatly reduced. In general, the more intense the color of tourmaline, the higher its value.

Distinguishing between real and fake tourmaline can be distinguished by the appearance, light transmittance, hardness, and characteristics of tourmaline. Tourmaline is a kind of tourmaline, which will have a certain adsorption after heating, which can absorb tiny dust or fine debris, while fake tourmaline will not appear such a phenomenon. So what else can be found on how to identify true and fake tourmaline, you can continue to understand.

1. Tourmaline can observe the inside of tourmaline through strong light irradiation, and it will be found that there will be relatively natural inclusions and cracks in the real tourmaline, while the internal texture of fake tourmaline is very pure, without inclusions and cracks, and will contain some bubbles.

2. The light transmittance of true tourmaline is very high, and the sunlight can show other colors after penetration, while the light transmittance of fake tourmaline is low, and the light will be darker after light projection.

3. The Mohs hardness of tourmaline is the degree, and the hardness can be compared by scratching the glass, and the surface of the real tourmaline will not show any scratches, while the fake tourmaline will have scratches.

4 Generally speaking, real tourmalines will have an appraisal certificate, while some glass-counterfeited tourmalines will not have a formal appraisal report.

Tourmaline comes in many colors, the common ones are red, rose, pink, blue, green, yellow, brown, black, etc. In short, through the above content, I believe that everyone has an understanding of the question of "how to identify true and fake tourmaline", and it can be known that distinguishing true and fake tourmaline can be identified from many aspects, keep the above points in mind, and you will not buy fakes when you buy tourmaline next time.

The quality of tourmaline can be seen as the color, the color of the tourmaline of good quality is bright, and the color of the tourmaline of poor quality is more sluggish. You can also look at the luster, the surface of good quality tourmaline is vitreous, and the surface luster of poor quality jadeite is relatively dull. You can also look at the texture, the texture of good quality tourmaline is crystal clear, and the poor quality jadeite has an obvious sense of fog.

1. The quality of tourmaline can be seen in color, and the quality of tourmaline is bright, the texture is thorough, and it is very transparent. Poor quality tourmaline has a sluggish color and lacks the natural "treasure" of natural tourmaline The inside also contains a tubular wrap.

2. The quality of glossy tourmaline can be seen by the luster, the surface luster of good quality tourmaline is very bright, glassy, and there is an obvious double shadow phenomenon at the bottom edge. Poor quality tourmalines have a dull luster and no ghosting effect.

3. The quality of tourmaline can be seen in the texture, the quality of tourmaline is crystal clear, the internal impurities are less, and it has a certain charge. Poor quality tourmaline texture has a pronounced haze and is not very transparent.

<>1. Clarity, the texture of tourmaline is relatively fragile and prone to cracks, which often contain a large number of inclusions, which will affect the clarity of tourmaline. Therefore, the pure tourmaline inside is very rare and belongs to the top grade, so when choosing tourmaline, try to choose a tourmaline with a pure texture.

2. Cut, the cut of tourmaline is also one of the factors that can best reflect its quality, generally speaking, the better the cut of tourmaline, the more blind changes can show its beautiful color, showing the best side of tourmaline. And a poorly cut tourmaline, even if its own quality is good, cannot reflect the beauty of the tourmaline itself.

3. Transparency, the higher the transparency of tourmaline, the better its quality and the more crystal clear. The surface of the Biqing Shenma Seal, which has poor transparency, will have obvious fog or opacity, and it does not look particularly transparent and appears relatively blurry.
