1, jewelry magnifying glass is the general name of magnifying glass used to observe jewelry, antiques and other collections, but it is not completely equal to jade appraisal magnifying glass. Jade identification magnifying glass is a subdivision of jewelry magnifying glass, which mainly tends to identify authenticity. Therefore, the magnification of the magnifying glass is required to be higher.

2. Because of the uneven hardness of mineral particles that make up jadeite, the jadeite particles after polishing are relatively large. When we observe the jade surface with naked eyes under the reflected light, we can see that the jade surface has a slight and uniform uneven appearance, commonly known as microwave pattern.

3. Generally speaking, if the polishing is rough, the microwave pattern is not obvious, and if the polishing is good, the microwave pattern is clear. The smooth transition between depression and ups and downs presents an uninterrupted phenomenon. As long as you see this phenomenon, it means that it is a natural A-goods jade, which is also an important feature to judge whether it is A-goods.

4. Compared with grade A jadeite, grade B jadeite is rough in texture, non-reflective, and there is no microwave pattern in imitation jadeite. The surface particles of jadeite are very rough, and the polished jadeite is easy to be observed by naked eyes. If the particles are fine, it is necessary to carefully observe whether there are microwave patterns (wipe off oil stains, sweat stains, handprints, etc.) in the highly reflective parts under soft light with a magnifying glass of 10 or even 20 times. ). This observation requires some experience.
