You bought a secondhand piece of jewelry, inherited one, or you’re simply not sure if what you have is real gold. Before seeking professional testing, there are a few simple tests you can do at home without special equipment. They don’t replace professional testing, but they’ll give you a good indication before you invest money or sell a piece of jewelry. <\/p>\n\n

\"Quality<\/figure>\n\n

What is considered real gold?<\/h2>\n\n

Pure gold is too soft for jewelry, so almost every piece is made from an alloy: gold mixed with other metals that give it strength and tone. “Real gold” means the gold content matches the hallmark on the piece, such as 585 or 750. Gold-plated jewelry, on the other hand, is inexpensive metal with a thin layer of gold on the surface, and its value is much lower. <\/p>\n\n

Gold marking table, karat vs. purity<\/h2>\n\n

The hallmark indicates the percentage of pure gold in the jewelry:<\/p>\n\n

Hallmark<\/th>Karat<\/th>Gold percentage<\/th><\/tr><\/thead>
375<\/td>9K<\/td>37.5%<\/td><\/tr>
417<\/td>10K<\/td>41.7%<\/td><\/tr>
585<\/td>14K<\/td>58.5%<\/td><\/tr>
750<\/td>18K<\/td>75%<\/td><\/tr>
875<\/td>21K<\/td>87.5%<\/td><\/tr>
916<\/td>22K<\/td>91.6%<\/td><\/tr>
999<\/td>24K<\/td>99.9%<\/td><\/tr><\/tbody><\/table><\/figure>\n\n

The higher the karat, the more gold in the piece, and the more expensive it is. But higher isn’t always better for everyday wear: high-purity gold is relatively soft and tends to scratch and bend. That’s why 14K and 18K are the popular choice for jewelry worn daily\u2014they combine a rich appearance with durability. <\/p>\n\n

Test 1: Purity Hallmark<\/h2>\n\n

This is the first test. Almost every real gold piece bears a tiny hallmark in an inconspicuous spot: on the inside of a ring, on the clasp of a necklace, or on the back of an earring. Use a magnifying glass or your phone camera’s zoom. <\/p>\n\n

Important to know: Numerical markings like 585 or 750 are considered clearer, but even a hallmark isn’t absolute proof. Complete absence of a hallmark is a sign that requires testing. <\/p>\n\n

Test 2: Magnet Test<\/h2>\n\n

Real gold is not attracted to a magnet. Bring a strong magnet close to the jewelry. If the piece is attracted to the magnet, it’s a very suspicious sign that it contains metal other than gold, or that part of it isn’t made of gold. Note that this is only an elimination test\u2014even fakes based on copper or brass won’t react to a magnet, so a normal result still isn’t sufficient proof. <\/p>\n\n

Test 3: Color and Wear<\/h2>\n\n

Real gold doesn’t rust like simple metals, and generally maintains a stable appearance over time. Check the areas that rub against skin, like the inside of a ring or the back of an earring. If a different tone appears there\u2014grayish or reddish\u2014it may be gold plating that has worn off, exposing the metal underneath. The color of solid gold tends to be uniform and warm, while worn plating looks flat and dull. <\/p>\n\n

Test 4: Weight and Density<\/h2>\n\n

This is the home test closest to accuracy. Weigh the piece, place it in a glass of water, and measure how much water is displaced\u2014this is the volume. Divide the weight by the volume to get density. For comparison: pure gold is about 19.3 g\/cm\u00b3, 18K around 15.5, and 14K around 13. Gold is very heavy relative to its size, and fakes made of light metal will behave differently. <\/p>\n\n

In practice, this test isn’t always accurate for jewelry with stones, hollow spaces, links, or complex shapes.<\/p>\n\n

Test 5: Vinegar\u2014Use Caution<\/h2>\n\n

Place a drop of vinegar or lemon juice on a small spot on the piece. Real gold generally shouldn’t change color from brief contact with household vinegar, but the test isn’t definitive and isn’t suitable for delicate jewelry. Don’t soak the piece in vinegar and don’t leave it immersed for a long time\u2014prolonged acidity can damage stones or other metal parts. <\/p>\n\n

Remember, home testing provides only an indication<\/h2>\n\n

None of the five tests provides complete certainty. Each tests a different aspect, and it’s worth cross-checking several of them to get a more reliable picture. If something doesn’t add up, or if it’s an expensive piece, it’s time for professional testing. <\/p>\n\n

Tests you shouldn’t do at home<\/h2>\n\n

There are tests circulating online that can damage your jewelry. Avoid them: <\/p>\n\n
