Is My Gold Real?
Test your gold at home with our interactive step-by-step guide
What markings do you see on your gold?
Look for small numbers or letters stamped on the inside of rings, clasps of chains, or backs of pendants. Use a magnifying glass if needed.

Guide by James Whitfield·Investment Research Lead·Last updated April 2026How to tell if gold is real — 6 home tests
Testing gold at home involves six key methods. The stamp check reveals the claimed purity. The magnet test identifies magnetic metals. Color inspection reveals the alloy composition. The ceramic scratch test checks for genuine gold streaks. The vinegar test detects reactive base metals. Finally, the density test measures if your item has the extreme heaviness of real gold. While no single home test is conclusive, combining all six gives you a strong probability assessment.
Understanding gold stamps and markings
Gold purity is marked using fineness (parts per thousand) or karats. 999 means 99.9% pure (24K). 916 means 91.6% pure (22K). 750 means 75% pure (18K). 585 means 58.5% pure (14K). 417 means 41.7% pure (10K). Warning stamps include GP (gold plated), GF (gold filled), GE (gold electroplate), HGE (heavy gold electroplate), and RGP (rolled gold plate) — these indicate a thin gold layer over base metal, not solid gold.
Professional gold testing methods
XRF (X-ray fluorescence) is the most reliable non-destructive test, reading exact elemental composition. Acid test kits use different strength acids for different karats. Electronic gold testers measure electrical conductivity. Fire assay is the most accurate but destroys a sample. Most jewelers offer free or low-cost testing. For valuable items, always seek professional verification.
Common gold fakes and how to spot them
Gold-plated brass or copper passes color tests but may fail the magnet test. Tungsten-filled gold bars match gold's density exactly, requiring XRF to detect. Gold-washed items have ultra-thin plating that rubs off quickly. Brass jewelry has a brighter, more orange color than real gold. Vermeil is gold plating over sterling silver (look for a 925 stamp).
What to do if your gold is fake
If gold-plated: the item has minimal gold value — keep as costume jewelry. If gold-filled: some dealers buy gold-filled items, as they contain ~5% gold by weight. If completely fake: buy from reputable sources in future. If uncertain: always get professional testing before selling or making decisions based on home test results.
Frequently asked questions
How can I test gold at home?▾
You can test gold at home using six methods: check stamps/hallmarks, magnet test, color inspection, ceramic scratch test, vinegar test, and the density test. Our interactive checker guides you through each step. No home test is 100% conclusive — for valuable items, professional XRF testing is recommended.
Is the magnet test reliable for gold?▾
The magnet test quickly identifies obvious fakes — if your item sticks, it contains magnetic metals. However, many fakes use non-magnetic metals like brass and copper. The magnet test rules OUT fakes but cannot confirm gold is real.
What does 585 stamped on my ring mean?▾
585 means 14 karat gold — 58.5% pure gold mixed with 41.5% alloy metals. This is the most common purity in the US and Europe. At today's price, 14K gold is worth USD 75.71/gram.
Is gold-plated jewelry worth anything?▾
Gold-plated (GP) jewelry has very little gold value — the layer is typically 0.5-2.5 microns thick. Gold-filled (GF) has more gold (~5% by weight) and some dealers buy it, but value is minimal compared to solid gold.
How much does professional gold testing cost?▾
Many jewelers test free when you visit. Professional XRF costs $10-30 per item. Home acid test kits cost $10-20 online. Fire assay costs $50-100+ and is destructive.
Can fake gold pass all home tests?▾
Yes. Tungsten-filled bars match gold's density. High-quality plating over non-magnetic metals passes magnet, color, and vinegar tests. Professional XRF testing is essential for high-value items.
What is the most reliable test for gold?▾
XRF analysis is the most reliable non-destructive test. Fire assay is the most accurate overall but destroys a sample. For home testing, the density test is the most scientific.
How do I know if my gold chain is real?▾
Check for a stamp near the clasp (10K, 14K, 18K, 585, 750, etc.). Hold a magnet to it. Check color in natural light. Green or black marks where it touches skin suggest worn-off plating.
