If it sinks, it’s likely real gold. If it floats, it definitely isn’t real gold. Real gold will sink to the bottom because it’s denser than water. Gold will also not rust, so if you see any signs of rust you know your piece isn’t real gold, and there’s no worry about damaging your item if it is indeed real gold.

Does gold float in water?
Gold is hydrophobic: it repels water. Because of this, even if the piece of gold is first completely submerged, if it gets near the surface it will throw off the water above it and float.Since most placer gold is flat and thin, its weight is small relative to its circumference so it will usually float.
