How do you recognize real gold?

For centuries, gold has held a special allure. Whether it's jewelry, coins, or antique objects, recognizing real gold is important to avoid disappointment and bad purchases. But how do you know if that shiny piece of jewelry is truly gold? In this blog, you'll learn various methods to test for yourself whether you're dealing with real gold.

Check the hallmark

The first and most reliable way to identify gold is to check the hallmark. In Europe, these are often numbers like 585 (14 carat), 750 (18 carat), or 999 (24 carat pure gold). You'll usually find these stamps on the inside of rings, on clasps of necklaces or bracelets, or on the back of earrings.

However, beware: stamps can unfortunately be forged. So, treat this as an initial indication, not as conclusive proof.

Identifying gold with a magnet

A simple test is the magnet test. Real gold is not magnetic. Hold a strong magnet near the jewelry; if it's attracted, it's likely not pure gold but a metal with a gold plating. Note that some alloys may contain small amounts of magnetic metals.

The weight of the gold

Gold is a heavy metal. A gold ring or necklace will feel heavier than a comparable item made of, for example, brass or aluminum. Compare your jewelry with a similar piece that you know for sure is real. Large deviations in weight can be a clear indication.

The shine and color

Real gold has a warm, deep luster that does not quickly fade or tarnish. Imitation and gold-plated jewelry can dull over time or acquire a coppery undertone. With fake gold, you sometimes see the gold layer wear off, revealing another type of metal.

The bite test

Perhaps the most famous test: the bite test. Real gold is soft and will leave a small indentation under light pressure from your teeth. While this sounds appealing, it is not advisable: you could damage your jewelry or strain your teeth. So, view this more as a historical anecdote than a practical test.

The density test

Another method is the density test. Fill a measuring cup with water and note the volume. Place your jewelry in it and measure how much the water level rises. By dividing the weight by the displaced volume, you can calculate the density. Real gold has a density of approximately 19.3 g/cm³. This method is quite accurate, but less practical without the right tools.

The ceramic test

Take an unglazed ceramic tile and gently rub the jewelry across it. Does it leave a gold-colored streak? Then there's a good chance it's real gold. A black streak often indicates another metal. Please note: this method can cause scratches, so be careful.

Have it checked by a jeweler

Still in doubt? Then a visit to the jeweler is the safest option. A professional jeweler has special tests and equipment to determine with certainty whether your jewelry is made of real gold.
