Brass oxidises in time (becomes brownish and maybe matte), so it needs to be polished. It contains copper, which may cause a dark shadow on the skin – this is not dangerous and can be washed off. Acid, sweat and salt enhances this process.
Brass can get scratched at exposed areas, e.g. by contact with other jewelry. We recommend you to take off your jewelry while sleeping, exercising or engaging in other activity that can scratch it.
Our jewelry are made of highpolished brass and is of course without nickel.
