No matter which kind of jewelry and crafts made from Burmese jade, we hope to buy the genuine A goods. Jadeite A is a pure natural jadeite. It has not been processed in the later stage, and its value is high, and the appreciation space is large. There are two methods of identification, one is identification by instrument and the other is identification by naked eye. At the time of purchase, you need to ask for a certificate. If the certificate is marked with natural jade, then it is A goods. No matter what word is added in front, it means that this jadeite is not pure natural, not A goods. Here is how to identify the jadeite A goods with the naked eye. We mainly observe the quality of Burmese jade through the naked eye, and see that it does not meet the requirements of pure natural jade. The first is to judge the nature. It is best to use a magnifying glass when observing, some of the crystal grains are relatively thin, and the naked eye cannot see the green. The second is to judge whether the color is natural. Jadeite A goods will not be treated by dyeing and other processes, and the color is pure natural. The color of natural jade is distributed along the direction of the texture, and gives the impression that the deep embedding in the jade does not give a feeling of emptyness. The transition between the colored part and the uncolored part is natural, with colored roots. If you use a Charles filter to observe, the natural Burmese jade will not turn red. The third is to judge the luster. The natural jade has a good luster and is translucent. When viewed, it is like the same water, bright and transparent, full of aura. The fourth is to judge the hardness and density. The hardness of the jadeite A is strong and cannot be compared with other gems. Place the jewelry in diiodomethane, and the natural jade will be suspended inside. The fifth point is to judge the sound. The sound of natural jade is clear and loud. We can use the agate stick to tap and listen to its voice to judge. However, the sound can only be used as a reference, because some of the B-good craftsmanship can make the sound sound very clear and loud, similar to the real Burmese jade. The above methods should be combined to judge, in order to identify the A goods. However, the most reliable method is to send it to the appraisal agency for identification and let the authority to produce the appraisal.
