Jade lovers should learn how to identify jade grading

The identification and grading of jade has always been a problem that has troubled jade lovers. For those who do not have a deep understanding of jade, it is difficult to tell the authenticity of jade, let alone distinguish the authenticity of jade with the naked eye. You can identify jade with the naked eye! Is this true?

Jade grading: look at the luster of jade

Why can experts tell whether jade is real or fake just by taking a look at it? Here we need to look at the gloss. Looking at the luster is just like looking at the "precious light" of an antique. This distinguishing feature is very useful for distinguishing between A and B grade jadeite.

①The luster of natural jadeite (commonly known as "A-grade" jadeite) is a typical glass luster, with a clear and moist feeling.

② The luster of bleached and filled jadeite (commonly known as "B-grade" jadeite) is worse, often with a wrong or even resinous luster and is relatively dull.

③ Techniques for observing gloss: Shake the jadeite back and forth and left and right when observing, and feel the intensity and uniformity of the jadeite's reflection through the reflected light from the surface.

Jadeite grading: second look at the jadeite's smoothness

Jade has a fine structure and high hardness, and its surface is very smooth after polishing. For example, if you compare a jade ring face with a green chalcedony (Australian jade) ring face, the jade ring face feels very smooth, while the green chalcedony ring face is relatively astringent and sticky.

Jadeite grading: three aspects to look at: the internal structure of jadeite

Structural jade has a fibrous interlaced structure, which is composed of countless tiny jadeite crystals interlaced together, and star-shaped and line-shaped light can be seen. Among them, the granular fibrous interlaced structure is composed of a mixture of fibrous and granular jadeite. In addition to star-shaped and linear light, flake-like light can also be seen. The granular structure is composed of coarser crystallized jadeite particles, and it is easy to see the jadeite nature, and it is mainly flake-like light.

The structure of fake jade is loose, the boundaries of crystal grains are unclear, and it does not have the clear porphyroblastic unequal grain structure of natural jade.

Jadeite grading: four aspects: look at the color of jadeite

The color of jade, especially green, appears in various shapes such as dots, veins, filaments, patches, etc. and is accompanied by color roots. This is one of the useful characteristics for identifying jadeite. Even on a ring face with full color, the color distribution in different areas is uneven (uniform color is very rare).

If the color distribution is uniform everywhere, the color is dull and has no spirit, it can basically be determined to be C-grade jadeite.
