You will get with every order a information how to handle the jewelry. Like every jewelry you have to care about. But I use my jewelry by my own daily and know that they are holding very long. But of course it depends how you use them.
The jewelry should not come in contact with water, especially, if its a hot day, because the wax will wash of the string, which will make it less lasting. If you use it careful it will make you happy for a long time. If you have any issues you can contact me anytime. Of course some polished stones, depends on the type can loose their glow, when they are to much into the sun.
