How is it that there are many white spots when the Taqing pendant is polished?

There are many white spots on the polished Taqing pendant, which may be due to the reduction of colloid structure of crystals in the epidermis under the action of water, resulting in the distribution of white spots on the jade surface.

If the Taqing pendant is not polished after purchase, it may have a rough surface and loose structure. After lighting, some light will pass through these white spots, so there will be many white spots. If the white spot is structural, it can be improved by grinding or adjusting the lighting angle.
