The most direct way to identify A-grade jadeite. You don't need to find an expert to identify it after reading this.

Natural A-grade jadeite is divided into jade bracelets, jade pendants and jade hand-held ornaments according to styles; divided into high ice type, ice type, ice glutinous type, glutinous type, oily green type, bean type, and iron dragon type according to its origin; and divided into emerald, sun green, emerald green, yellow jadeite, red jadeite, oily green, blue water, clear water, water green, and ice white according to color.

The functions of A-grade jade bracelets generally have three aspects: one is to show identity and highlight personality; the second is to beautify the arms; and the third is to maintain health. Bracelets are usually worn on the left hand. Bracelets with gemstones should be worn close to the wrist; those without gemstones can be worn loosely on the wrist. Only pairs of bracelets can be worn on both wrists.

Identification

1. Texture. Natural jade is transparent or translucent in texture, with an oily and shiny surface. Upon closer inspection, you can see nearly round, slightly transparent "salt grains" and fibrous substances surrounding them.

2. Hardness. Natural jade is hard jade with a Mohs hardness of 7. It will not leave any marks if carved with a sharp knife. Fake jade has a low hardness and can be carved with marks by a sharp knife.

3. Jade nature. When observing natural jade under strong light, you can see emerald flashes of other mineral particles inside it, which are called jade flowers or jade properties. Fakes made of glass, plastic, or porcelain do not have this "jade property" feature.

4. Relative density (specific gravity). Natural jade has a hard and tight structure, no bubbles, high density, and a crisp sound when knocked; fake jade has a loose structure or has bubbles, low density, and a hoarse, unclear sound when knocked.

The most direct way to identify A-grade jadeite is to learn to see its flaws. Why do I say that? Because A-grade jade is a crystalline mineral formed under high pressure, low temperature and in areas with intense crustal movement, its harsh formation environment means that it usually has scars, or flaws. And those few perfect A-grade jadeite are not found in the ordinary jewelry market, so learning to see flaws is the most direct way to identify A-grade jadeite.

Another flaw of A-grade jadeite is "dirty spots", which are black crystal particles or impurities inside the jadeite. First of all, glass or other quartzite imitations will not have this feature. Secondly, B-grade jadeite will not have it, because B-grade jadeite has been cleaned with strong acid to remove impurities and unclean base color. Therefore, if the base of the jade jewelry is particularly clean, without any yellow or gray components, and it looks white to the naked eye, then you have to suspect whether it is B-grade jade.

The surface of A-grade jadeite is usually not perfectly smooth. When observed under magnification, some pits can often be seen. These pits are usually caused by natural defects or improper post-processing. However, this must be distinguished from the acid-etched reticulation on the surface of B-grade jadeite.

Due to the diversity of jadeite varieties, even among samples with poor water head, there will be a few areas with uniform and fine texture. Therefore, glow observation has broad significance. The glow reflects the combined effects of reflection, refraction, scattering, interference and diffraction of light by tiny crystal faces and cracks in the jade structure, which is similar to the moonlight effect.

It is quite common for A-grade jadeite to have cracks between crystals (which appear as ice debris) and stress cracks (which appear as large cracks running through) due to crystallization and geological stress, especially in jadeite with poor water head. White cracks are an important sign of A-grade goods.

For operators and consumers who are only interested in A-grade jade, to a certain extent, distinguishing between A-grade and B-grade jade means understanding the difference between real and fake jade. Of course, the actual situation is much more complicated than the above introduction, so comprehensive consideration is necessary.
