Amber will also have a fluorescent reaction disappearing after long-term wear. Usually, some old amber has lost its original fluorescence reaction under the light. Amber will also have some cracks, even broken... So, what happens when amber does not react?
Under normal circumstances, amber is exposed to sunlight or light for a long time, causing radiation inside the amber, causing undesirable physical damage.
Amber reacts with oxygen to turn amber into a tan, and even cracks when the temperature is too high.
In high temperature or dry environment, the phosphorus and moisture in the amber will evaporate, causing the amber to lose its luster and even cause surface cracking.
