GoldQuestions
Is my gold real?
No single home check proves gold is real. A sensible process combines paperwork, dimensions, weight, markings, and professional testing when value or doubt is significant.

Start with the lowest-risk checks
Before using acids, filing, or destructive methods, start with non-destructive checks: product details, invoice, dimensions, weight, packaging, serial numbers, and whether the seller is known and traceable. For coins and bars, compare the item with official mint or refiner specifications. For jewellery, check hallmarks, construction, wear patterns, and whether the item description matches its weight and appearance.
Build confidence from several signals
One check is weak evidence. Several consistent checks are stronger. A genuine-looking coin with correct weight, diameter, thickness, edge detail, sound, invoice, and dealer provenance is more convincing than one that only passes a magnet test. The same principle applies to bars: serial numbers, packaging, assay details, dimensions, and dealer records should agree. If one signal conflicts with the rest, slow down.
Reliability table
These checks can raise or lower confidence, but none should be treated as a guarantee on its own.
| Check | Reliability | Why it is limited |
|---|---|---|
| Magnet response | Low | Gold is not magnetic, but many non-magnetic metals are also not gold |
| Weight and dimensions | Medium | Useful for known coins and bars, but plated or filled items can be engineered to mislead |
| Visual marks and packaging | Medium | Helpful for consistency checks, but marks and packaging can be copied |
| Specific gravity | Medium to high | More informative when done carefully, but technique and reference data matter |
| XRF, ultrasound, or professional assay | Higher | Professional tools improve confidence, though method and operator quality still matter |
When doubt is expensive
If the value is meaningful, professional testing is usually cheaper than a serious mistake. XRF, ultrasound, density checks, or assay services may be appropriate depending on the product. Private-sale bargains, inherited items, damaged packaging, and unfamiliar foreign products deserve extra care. A seller who resists normal checks, pushes urgency, or avoids traceable payment routes increases the risk regardless of how the item looks. A clear invoice from a recognised dealer is not absolute proof, but it is much stronger evidence than an anonymous cash sale with no return route.
Key points
No single home check proves gold is real. Start with non-destructive checks and official specifications. Combine paperwork, weight, dimensions, marks, and seller traceability. Avoid damaging an item without a reason. Use professional testing where value or doubt justifies it. Keep a note of who tested the item, which method they used, and whether the test affected packaging or resale condition.

FAQs
Is the magnet test enough?
No. It is only a quick screen and cannot prove authenticity.
Can fake gold pass simple checks?
Yes. Some counterfeits are designed to pass basic visual or weight checks.
Who can test gold professionally?
Bullion dealers, assay offices, jewellers with suitable equipment, and specialist testing services may be able to help.
Can a real-looking coin still be fake?
Yes. Some counterfeits are designed to look convincing, so dimensions, weight, provenance, and stronger testing may all be needed.
