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 gluedin gemstones, as it can loosen the glue. However, if youre looking to clean heavilysoiled jewelry made entirely out of gold or gold jewelry that contains strong gemstones (like diamonds), boiling is a great choice.
