Jade bracelets can be covered with silver, but the grade of jade bracelets covered with silver will be reduced and their value will be greatly reduced.
You can also choose to find someone to repair the cracks with gold tracing. If the surface of the jade bracelet is thrown out of the hole, some gold or silver can be embedded in the hole, which not only repairs the hole on the surface of the jade bracelet, but also improves the grade sense of the whole bracelet a lot.
If the cracks on the surface of jade are small, it will not affect the firmness of jade, but the beauty will be reduced. You can go to the jewelry store for inlay treatment, and use gold inlay to cover up and beautify the cracks, which can make jade more beautiful.
