Jade is generally translucent, and it will glow when illuminated by a strong flashlight. Under the light, it will show the texture structure of jade, and the materials in different parts will generally change (color, permeability, etc. ) Porcelain is generally opaque and needs to be very thin to have a transparent effect. After polishing, most of them have no halo, and even if they do, they can't see the jade structure, and the material is uniform.
