Well, Archimedes did it by weighing the "gold", calculating how much space it ought to take up, then dunking it into a full tub of water to see how much space it actually took up. If it helps, the density of gold is 19.3 grams per milliliter. The tub has to be exactly brim-full, you have to lower the "gold" in without splashing, and you have to have something to catch the water. The volume of water spilled is the same as the volume of the "gold".

Real gold is very soft. It also has a specific ring to it when dropped on a table. Fake is usually made from copper or zink then plated. It will be hard and sound more tinny when dropped

Gold has a very unique texture. When you rub it with your fingers, it feels like you are rubbing off paint off a surface, but your fingers end up clear.
Fake gold tends to cause rashes and itchiness when worn. Real gold doesn't do that, and it also never stops shining. Hence its value.

If you don't maind destroying whatever it is you wish to test, drop it in conc. sulphuric acid: gold will not disslove unless you use aqua regia - a mixture of sulphuric acid and nitric acid.

Get a touch stone and rub it on it.
