Bring water to a boil

You dont need to boil much water just enough to submerge all of the jewelry in. As youre waiting for the water to boil, set your gold jewelry in a sturdy bowl or another vessel that wont be damaged by boiling water. Pyrex or metal cooking bowls/dishes are good choices. Arrange jewelry in the dish or bowl so that no piece of jewelry is covering up another piece water should be able to reach every piece of jewelry.
