Tangled Gold filled chains can be frustrating, especially when the knot is small and tight. The good news is that you usually do not need to pull hard or take the chain to a jeweler right away. With a little patience and the right method, you can often loosen the knot at home without damaging the chain. Whether it is a gold filled necklace, bracelet chain, or a delicate piece with a pendant, the key is to reduce tension first and work on the knot slowly.
