The magnet test is the simplest method for checking the purity of gold at home. Gold is a non-reactive and non-magnetic alloy, whereas the majority of other metals are magnetic. As a result, putting actual gold near a magnet will have no results.

The Float Test is one of the most basic gold preliminary tests you may do at home. A cup (or bowl) of water and your gold item are all you need. You only need to drop your gold piece into the water!

If it’s real gold, it will just sink to the bottom of the cup right away. Because of its high density (19.32 g/ml), pure gold is heavy. If your gold object floats or hovers over the bottom of the cup, it’s either false or plated gold. This is due to its reduced density (12.9 to 14.6 g/ml for 14K, 15.2 to 15.9 g/ml for 18K, and 17.7 to 17.8 g/ml for 22K).
