These problems should not be the quality problems of the crystal itself. The difference between a good crystal and a bad crystal lies in its purity, and its basic composition is the same. Even if there is a small crack in it, it will never float to the surface without great impact.

After wearing for a long time, the crystal beads will touch hard objects such as tables and doorframes outside. Beads made of cowhide tendons, because of their elasticity, will be tightly squeezed together. When wearing activities, the contact points between beads will wear each other, especially when playing badminton. If you are used to wearing multiple strings of crystals at the same time, the situation will be more serious. Pay special attention to this when wearing crystal beads with fine cross section.

Also, you should pay attention to the fact that all kinds of gems should not be concentrated in a unique jewelry box at the same time. Otherwise, they will rub against each other and cause wear.

Finally, the composition of crystal is actually similar to that of glass. Will be corroded by alkaline substances, resulting in mottled and dim surface. So it's best to take off the crystal products when washing your hands.
