Sabine, Gold is an acceptable metal for body piercing jewelry,
however, you must not use any with nickel in the alloy. The use
of 14kt or 18kt yellow gold, or Palladium white gold is
especially safe after the piercing has begun to heal. We make
body jewelry all the time out of gold and have never had any
Sterling silver however should NEVER be put in a body piercing.
It reacts badly and can cause horrific infections and piercing
Stick with your most non-reactive gold alloys you’ll be just
fine. Also make sure to get a VERY good polish on the metal, as
small grooves, scratches, or rough spots can hold bacteria and
cause a whole barrage of problems themselves.
