Emerald appraisal
The jadeite as high -end jade is high. The value of natural jadeite A goods and artificial glue processing emerald B goods and dyeing treatment of jade C goods is very different. The market is full of artificially handled sub -jade. Some people say that using the Dao's color filter to take a piece of green jadeite. If it transforms into red, it can indicate that this jadeite is dyed, and the color does not change color. This statement is very mechanical and the understanding of people. Is we know that the Dow's color filter is a color filter film, which only allows red light and orange light to pass through. The dyes used for dyeing emerald generally contain chromium salt. When it is very high, it will emit red light, and it appears red under the Dao's color filter mirror. However, if the color of the dye is not dark, the concentration of chromium salt is not high, and it is reddish under the Dao's color filter mirror, which is not easy to observe. In addition, natural green emeralds sometimes contain a small amount of red light, so it is used to observe the green emerald with the Dao's filter to analyze it carefully. So what is the difference between the natural green of emerald and dyed? We already know the reason for dyeing emeralds, and the reason why natural jadeite is green, white, and purple because the grains that make up the jadeite are green, white, and purple. So when we look at the color of a natural jadeite, its color and crystal cannot be divided into boundaries, and the original crystals, its original crystal is not color, and the dyeing agent that enters the emerald is along the crystal. The gap between the granularity or some fine cracks is infiltrated, so the color and crystal will have obvious divisions. diamond appraisal diamonds are the hardest substances in natural substances. Diamonds can be carved with any other gemstone, but any other gems can be scratched by diamonds. The most accurate and reliable way to distinguish is to use the "heat -guided meter" to measure heat -conducting data to distinguish between true and false diamonds, but the price of "thermal guide" is more expensive. Since the diamond is a noble and luxurious jewelry, the market uses cheap gems, artificial gemstones and even glass to replace or claim that diamonds are often seen. The commonly -colored fake diamonds have the following: ① 锆 ：: And with the stones: and with Diamonds are extremely similar and are the best substitutes for diamonds. The appraisal method is that because the vermiculite has polarization and a large double refractive index, when the vermiculite edge after 10 times the large mirror is used to observe the processing of the processing, it can be seen from its top surface. Shadow, and diamonds have no phenomenon. ② Glass: The discount rate of glass is very low, and there is no flashing color light of diamonds; especially sinking into the water, the glass products are glory at all, and immediately expose the horse's feet. ③ Soviet diamond: That is, cubic oxidation, the earliest was successfully developed by the Soviets, hence the name. Soviet diamonds are artificial compounds, but they are very close to natural diamonds in terms of scattered and folding. They also have the seductive appearance of "fire". But its hardness (8.5) can be distinguished from each other. And thermal conductivity is much lower than that of diamonds, which can be identified by the "hot guide" and accurately distinguish it.
Regular, the state recognizes the jewelry appraisal center
