There are other tools such as gold brand, the touchstone and chemical methods to distinguish the real gold from tungsten gold-plated products.
Tungsten gold-plated product is covered with a thin coat of gold. You can make some distilled water, take your jewelry sharpening, then put the jewelry into the distilled water, out of the distilled water for a while. If it is not gold plated jewelry, it will not change color.
This is an easy test, but it is not an all-encompassing or full proof way to distinguish between real gold and gold-plated product . Something as weak as a fridge magnet will not be useful, but stronger magnets that you can find in specialized hardware stores or in common objects such as women's purse latches, children's toys, or even in old unused hard drives will be strong enough to perform this test. Hold a magnet up to the item, gold is not a magnetic metal, so if it pulls towards, or sticks to the magnet, it's tungsten gold-plated product. However, just because it doesn't react to the magnet doesn't mean it is not tungsten gold- plated product, as non-magnetic metals are used in counterfeit pieces as well.
Tungsten gold-plated product is anything less than 10 Karats. If you are wondering whether your jewelry is tungsten gold-plated product or not, the most reliable way to find out is to take it to a certified jeweler and have it tested. If you want to check for yourself, the mentioned above tests you can conduct to tell if your gold is real or tungsten gold-plated product.
