If you don't wear it for a long time, don't brush the amber surface with a toothbrush. This will make the surface of amber rough and lose its original luster because of friction, which is not worth the loss. Our correct approach should be to soak amber in warm water of 30-40 degrees for 2-3 minutes, and then dry it with a soft cloth.
Try to avoid bright light. Generally, sunlight and light are completely fine. Because amber has a low melting point, if there is fire around, don't let amber come into close contact with it.
If amber is rough due to friction, we should apply a little toothpaste on the surface, then wipe it with a soft cloth, and finally wash it with a soft cloth dipped in water, and then apply a little olive oil to restore its original luster.
Amber has been buried in the deep sea and underground for tens of millions of years and has been protected by nature. When they are excavated or washed ashore, they will accelerate evaporation and oxidation in the air. If they are exposed to air and sunlight for a long time, the color of amber will deepen quickly, and water loss will cause cracks on the surface, which will seriously affect the ornamental value of the inclusions inside. In addition, waxing the outer layer of amber after peeling and polishing will sometimes harm the long-term collection of amber, because some waxes contain clean chemicals.
