We can't generalize. Some good jewels and jadeites may be real, but they may also be imitations or processed jadeites. The authenticity of jadeite can be judged from the following aspects:

1. Color: Real jadeite usually has unique colors, such as emerald green and apple green. If jadeite is too bright or unnatural, it may be dyed or forged.

2. Glossy: Real jadeite has the luster of oil, and it will give off charming light under the light. If the surface of jade is dull or the light is not obvious, it may be inferior or forged.

3. Texture: The texture of jadeite is unique. Real jadeite is usually fine and even in texture. If the texture of jadeite is unclear or uneven, it may be inferior or forged.

In addition, jadeite can be appraised by professional appraisal institutions, such as Gemo Logical Institute(GIA) in the United States, who will use professional instruments and technologies to judge the authenticity of jadeite.

It should be noted that there are many imitations and fakes on the market, and manufacturers will use various means to make them look closer to the real jade. Therefore, when buying jade, you should choose a reputable merchant and learn as much as possible about jade in order to make a more accurate judgment and choice.
