Most gold used in jewelry is actually a mix of silver and gold. Like gold silver isn't attracted to a magnet. There may even be other metals like copper platinum or nickel mixed with the gold to give it different colors. They also make it harder so it doesn't bend or scratch. So even if you gold isn t magnetic that doesn t mean it s pure.
