As with most jewelry, wear with care!
Most jewelry does not do well exposed to moisture or extreme elements, long necklaces can catch on door knobs, drawers. kids pulling or pets! Again just wear with care!
All my pendants and chains are Lead and Nickel free.
Pendants are water resistant but not waterproof, I recommend removing before showering, bathing or swimming.
I'd also recommend putting on lotions or perfumes first before putting on your pieces. Some chemicals in these products could deteriorate your jewelry.
