You bought a secondhand piece of jewelry, inherited one, or you\u2019re simply not sure if what you have is real gold. Before you seek professional testing, there are a few simple tests you can do at home without special equipment. They don\u2019t replace professional testing, but they\u2019ll give you a good indication before you invest money or sell a piece of jewelry. <\/p>\n

What is considered real gold?<\/h2>\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. \u201cReal gold\u201d 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

Gold Hallmark Table: Karat vs. Purity<\/h2>\n

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

\n\n\n\n\n\n\n\n\n\n\n\n
Hallmark<\/th>\nKarat<\/th>\nGold percentage<\/th>\n<\/tr>\n<\/thead>\n
375<\/td>\n9K<\/td>\n37.5%<\/td>\n<\/tr>\n
417<\/td>\n10K<\/td>\n41.7%<\/td>\n<\/tr>\n
585<\/td>\n14K<\/td>\n58.5%<\/td>\n<\/tr>\n
750<\/td>\n18K<\/td>\n75%<\/td>\n<\/tr>\n
875<\/td>\n21K<\/td>\n87.5%<\/td>\n<\/tr>\n
916<\/td>\n22K<\/td>\n91.6%<\/td>\n<\/tr>\n
999<\/td>\n24K<\/td>\n99.9%<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/figure>\n

The higher the karat, the more gold in the piece, and the more expensive it is. But higher isn\u2019t always better for everyday wear: high-purity gold is relatively soft and tends to scratch and bend. That\u2019s why 14K and 18K are the popular choice for jewelry worn daily: they combine a rich appearance with durability. <\/p>\n

Test 1: Purity Hallmark<\/h2>\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\u2019s zoom. <\/p>\n

Important to know: Numerical markings like 585 or 750 are considered clearer, but even a hallmark isn\u2019t absolute proof. Complete absence of a hallmark is a sign that requires testing. <\/p>\n

Test 2: Magnet Test<\/h2>\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 clear warning sign that the piece contains other metals, or that only part of it is actually gold. Note that this test can only rule gold out: fakes based on copper or brass won’t react to a magnet either, so a normal result still isn\u2019t sufficient proof. <\/p>\n

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

Real gold doesn’t corrode the way base metals do, 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, grayish or reddish, it 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

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

Of the home tests, this is the one that comes closest to a real measurement. Weigh the piece, place it in a glass of water, and measure how much water is displaced: this 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

In practice, this test isn\u2019t always accurate for jewelry with stones, hollow spaces, links, or complex shapes.<\/p>\n

Test 5: Vinegar (Use with Caution)<\/h2>\n

Place a drop of vinegar or lemon juice on a small spot on the piece. Real gold generally shouldn\u2019t change color from brief contact with household vinegar, but the test isn\u2019t definitive and isn\u2019t suitable for delicate jewelry. Don\u2019t soak the piece in vinegar and don\u2019t leave it immersed for a long time: prolonged acidity can damage stones or other metal parts. <\/p>\n

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

None of the five tests provides complete certainty. Each tests a different aspect, and it\u2019s worth cross-checking several of them to get a more reliable picture. If something doesn\u2019t add up, or if it\u2019s an expensive piece, it\u2019s time for professional testing. <\/p>\n

Tests you shouldn\u2019t do at home<\/h2>\n

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