Nothing. Gold is inert with bleach. Bleach can effect the other metals in the alloy as most gold items are not pure gold. If the piece contains silver or copper, the bleach can affect those metals.Most items we call gold are not pure gold but are mostly gold alloyed with other metals. 14k gold for example is 14 parts pure gold and 10 parts other metals ( such as silver and copper) However the gold itself is not harmed in anyway
