Have you found a problem recently, more and more people have begun to be interested in the blue turquoise, and even directly say no green, as long as the blue. However, many people are familiar with turquoise, and few people know about blue turquoise. In fact, blue turquoise is another name for turquoise, which means that turquoise is blue turquoise. The biggest difference is the difference between blue and green. The colorful turquoise is deeply loved by the majority of friends. The strong green color makes the wrist look more white, and the round beads make you love it. There is only a blue-colored turquoise in the market. What does it have to do with turquoise? What is the difference between bluestone and turquoise that can be easily distinguished by the naked eye? Turquoise, also known as blue turquoise, is an opaque gemstone with a variety of colors such as light blue, medium blue, green blue, green, etc., with mottled colors, dark spots and textures (turquoise texture commonly known as iron wire). The quality of the turquoise is relatively dense, which is good for polishing the color; the poor quality of the porous, easy to lose water and fade after the sun. Turquoise green is caused by iron, and blue is caused by copper coloration. The quality of the evaluation criteria is that the bluer the color, the better the wire, the less the wire. Listening to the name, most people may think that turquoise must be the most valuable green. In fact, this is not the case. According to the domestic turquoise classification, the bright sky blue is the color that the first turquoise should have, and also the luster. Strong, translucent to slightly transparent, the surface has a glassy feeling; the texture is dense, delicate, tough, without iron wire or other defects, the block is large, can be regarded as a level of turquoise. This is the basis for the grading of turquoise in China's arts and crafts industry: color, luster, texture and blockiness. Secondary turquoise: dark blue, blue green, emerald green, strong luster, slightly transparent. The texture is tough, the iron wire or other defects are few, and the blockiness is medium. Three-level turquoise: light blue or blue-white, light yellow-green and other colors, poor gloss, relatively stiff texture, obvious iron wire, or more defects such as white brain, tendons, and heart, and the block size varies. As turquoise minerals are declining, their prices are also rising and not falling. How to choose the best quality turquoise, can not only achieve the effect of decoration, but also play the role of investment preservation? The purchase of turquoise can be carried out according to four factors: color, texture, distribution of iron wire and weight. 1. Color: The color unique to turquoise is present due to the coloring ions contained in the body. When the turquoise contains more copper ions, it tends to blue; when it is contained in turquoise The more iron ions, the greener. Therefore, turquoise can be divided into three categories according to color: blue, green, and gray (white). Its value is the best of the sky blue turquoise, followed by dark blue, blue green and light gray blue, the more balanced the better. 2, texture: density is one of the most important aspects, high density turquoise, smooth surface, polished color, surface less holes, not easy to fade. On the other hand, it is determined by the structure of turquoise, and the structure is dense. According to the texture from excellent to secondary classification: transparent turquoise, massive turquoise, blue turquoise, iron turquoise, magnetic turquoise, spotted turquoise. Transparent turquoise is very rare and extremely valuable. 3. Iron wire distribution: Irregular black lines in turquoise are called iron wires, and the black or brown spider mesh pattern on the mesh is an iron wire formed by iron oxide. The better turquoise should be that the iron wire is evenly distributed, not too thick or too thin, the lines are clear and pleasing, and the iron wire should be as small as possible, and this naturally formed texture may have a special pattern. Its value doubles. 4. Weight: Turquoise with similar color and quality should be collected in a large, positive shape. At present, more than 15 kilograms of turquoise is very rare on the market, so more than 15 kilograms of turquoise can not be determined by its weight alone, and its collection value is much higher.
