To find the density of your gold item, divide its volume by its weight. For example, if your item weighs 40 grams and has a volume of 2.2 milliliters, its density will be 40 / 2.2, which is 18.18 g/mL. Since the density of gold is 19.3 g/mL, the chances are your item is mostly real gold.
Can brass be mistaken for gold?
Brass is not a fake gold; it is an alloy that consists of copper and zinc. If the product contains more copper, it will give a more yellow tone, while more zinc provides a whiter tone.

How do you test a brass with a magnet?
Solid brass is not magnetic. If the magnet sticks, the item is usually steel or cast iron, with a brass plating. If the magnet does not stick, you can test further by scratching a hidden area with a sharp tool. If you see a shiny yellow scratch, the item is likely solid brass.
How can you tell real brass?
You can tell the difference with the help of a magnet. If you hold a magnet against the item and feel a pull, you know the piece is brass plated. If there’s no attraction, then the piece is solid brass. That’s because the underlying metal is usually iron or steel, both of which are magnetic.
