The dark oxidization is a surface patina and, with continued use, will eventually wear back to silver, where it gets rubbed, with the deeper textured parts staying dark, which will make the bracelet unique to you since it reflects how you've used it in your life.
If you really love the dark look though, it can be re-oxidised, free of charge whenever you like (just drop me a message here).
The bronze details will develop a patina resulting from oxidation, due to the chemical reaction, that happens when the metals are exposed to the atmosphere and this is a natural process. However, it can be easily cleaned and polished to restore its original appearance. Use the polishing cloth I provide with every order to polish them.
