Unlike silver, Gold doesn't develop a dull tarnished finish over time. However, gold can still easily accumulate dirt and grime with normal use. Read this wikiHow to learn how to restore the shine to your precious rings, bracelets, necklaces, and other gold Jewelry.
How to Use Boiling Water
Know when boiling is appropriate. Gold itself can be boiled with no problems. However, boiling delicate gemstones (like opals, pearls, coral, and moonstones) can cause them to crack or become damaged - especially if the jewelry is cold before boiling. Boiling is also a bad idea for jewelry with glued-in gemstones, as it can loosen the glue. However, if you're looking to clean heavily soiled jewelry made entirely out of gold or gold jewelry that contains "strong" gemstones (like diamonds), boiling is a great choice.
Bring water to a boil. You don't need to boil much water - just enough to submerge all of the jewelry in. As you're waiting for the water to boil, set your gold jewelry in a sturdy bowl or another vessel that won't 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.
Carefully pour the water over your jewelry. Be very careful not to spill or splash by pouring too rapidly - boiling water can cause serious burns. When all of the jewelry is completely submerged, you've added enough water.
Wait for the water to cool. When you can comfortably put your hands in the water, you can remove the jewelry. Follow a good boiling by scrubbing each piece of jewelry with a soft brush, then dabbing it dry with a soft towel and allowing it to sit and air-dry completely.
Don't be afraid if the water appears dirty - this is good! As boiling water loosens the dirt, wax, grime, etc. that's built up on your jewelry, it may float to the surface of the water. The dirtier your water looks, the more dirt you've removed from your jewelry!
