Whether you can scratch the glass may be effective for those fakes that use glass to imitate jade, because these "fake jade" have low hardness and certainly can't scratch the glass. However, it is a high-end product made of low-end jadeite (grade B and C jadeite) and cannot be identified by this method.
In addition, using jade glass to test the authenticity of jade may also damage the quality of jade itself. Therefore, it is suggested not to use this unscientific method to detect jadeite again.
Extended data:
The identification of jadeite requires two necessary conditions: professional knowledge and practical experience. The identification of jadeite bracelets can be summarized as four points: seeing, touching, weighing and listening.
Jewelry experts said: When touching the jade bracelet, it will feel unusual and have a cold touch. Natural jadeite is hard in texture, translucent to transparent, with good surface gloss and oiliness. Through magnifying glass or microscope observation, you can see the round slightly transparent "salt particles" and the fibrous substances around them.
Observing jadeite under strong light, we can observe the transparency, luster and internal structure of the crystal. If it is natural jade, we can observe it under strong light, and we can see that there are emerald flashes from other mineral particles inside. This flash is called Emerald or Cui Hua.
