1. Friction method: Two beads are gently rubbed, and there is resistance. Real pearls rustle and fake pearls slide like glass balls. When natural pearls are rubbed, pearl powder will appear at the same time. When the pearl powder is wiped off, the skin of the pearl is still smooth.
2. Bite method: Pearl teeth often have a concave-convex feeling, and white powder will appear, while fake pearls bite hard and the coating will partially fall off.
3. Look at the hole: there is a layered structure in the perforated hole of the pearl, but a careful inspection of the fake pearl will reveal that there is no layered structure in the hole.
4. Magnifying glass observation method: When observed with a magnifying glass 5 times or 10 times, growth lines can be seen on the surface of real pearls (including natural pearls and cultured pearls), as if sand dunes were blown by the wind; Artificial beads can only see the eggshell-like coating.
5. Find a professional organization for appraisal.
6. Touch it gently with your hand, and it feels great.
