To perform this test to check if gold is real, make a light, tiny scratch on the item using a small nail file. Choose a spot that is not noticeable if possible. Use a dropper to apply a small drop of nitric acid to the scratch. If there is no reaction, then the piece is probably made from real gold.Source: https://www.goldkingsonline.com/how-to-tell-if-gold-is-real
To tell if gold is real or fake, measure its density. The density of gold, 19.3 grams / cm3, is much higher than most other metals. Even lead has a density of only 11.4 g/cm3 -- platinum, iridium, osmium, and neptunium are the only metals that have a density over 20 g/cm3! (For comparison the density of water is only 1 g/cm3).
To measure the density of a metal, you need a scale or balance (to measure the mass) and a graduated cylinder (to measure the volume).
First weigh the piece of gold on the scale. Then, to determine the volume, add some water to the graduated cylinder. It doesn't matter how much, but write down exactly how much there is.
Then add the gold to the graduated cylinder. Again, write down the exact water level. Take the difference of the two numbers to get the volume of the gold alone. Remember 1 milliliter = 1 cm3.
Finally, find the density by dividing the mass by the volume (density = mass ÷ volume). If what you get is approximately 19 g/cm3, then it is real gold. It might be slightly less because almost all gold jewelry is not actually 100% gold (pure gold is too soft for jewelry). Note also that this method won't work if there parts of the jewelry that are not gold (like gems, etc.) because the density you measure will be affected by those other non-gold parts.

Answerreal gold is softer than fake, which is why you always see people biting rings and such, to see if it dents. If it does not, it is fake AnswerOr, if you'd like to not have to do a complicated impossible solutions and NOT chip your teeth;
use a magnet on the piece, if it's attracted strongly to the magnet, it's not gold- if it isn't attracted or has a VERY light attraction;
Buy a nitric acid test kit on E-Bay for $20-$30, Rub the piece on the test kit stone, drip a drop of nitric acid onto the rubbing and see if it fades off- if it does, it isn't gold.
another way is get a coin mould and they have some at your nearest pawn shop...just melt it until it fits on the right coin mould.each tell how much its worth.
Fake gold, or "fools gold" has a foul sulfur odor while real gold does not. Usually, you can rub the gold and sniff it to determine if it is real or fake.
no because the real gold will mark with a small bite, the fake gold wont
Fools gold (Iron Pyrites) is crystaline in form and looks jagged, wheras real gold does not form crystals, in natural form it has a realtively lumpy appearance.
Not many fake coins are made from real silver or gold. Take it to a jeweler to be tested, most will do this for you.
You can tell if a ring is real gold or not by putting it near a magnet. If the ring is attracted to the magnet it is not real gold, real gold is not magnetic at all.

I was wondering the same thing. I can tell real gold from fake just by looking and the 'gold' that i saw that had FAS on it was surely not real gold.

In order to tell if gold jewellery is real, one would have to look from any characteristic traits that would distinguish it from fake gold (such as "Fool's Gold"). Websites that offer information about this feature include: "usellgold" and "cashgoldexchange".
Not necessarily. They are more for the attraction. However, it is possible if the watch was very expensive. Go check it out where an expert can tell you if it is real or fake.
you have to have the real one and see if its fake or not
We tell real gold by its weight.
How can you tell a real Vacheron watch from a fake or reproduction?
you throw it on the ground really hard and measure the height of which it reaches on the first bounce
