Is the crystal bracelet afraid of chemical things?

First of all, suppose that the bracelet of the subject is really made of crystal.

The main component of the crystal is silicon dioxide. Silicon dioxide is a very inert substance in chemistry and can only react with hydrofluoric acid or fluorine at room temperature. If you don't know what hydrofluoric acid is, it is almost certain that it will not appear in your life. They are all highly toxic and are usually found in specialized laboratories or chemical plants. Don't worry about this. In addition, it reacts with alkali at high temperature. If the subjects don't work in the laboratory, there should be no condition and elegance to heat the bracelet with high concentration of alkali. So in a word, if it's just daily life, silica, that is, your crystal bracelet, is absolutely super strong, so you don't have to worry about corrosion at all, but it would be better if you could clean it regularly. In addition, the hardness of silicon dioxide is relatively high, and the subjects can find a knife to scrape on it without scratches.

Of course, all this is based on the fact that your bracelet is really a crystal bracelet.
