How to Tell if Gold Jewellery Is Real: Hallmarks, Stamps & Tips

How to Tell If Gold Jewellery Is Real (A Simple, Confident Guide)

Buying gold jewellery should feel exciting — not stressful. The good news is: real gold usually leaves clues. With a quick stamp check and a few smart habits, you can shop with confidence in Canada and anywhere in the world.

Here’s how we recommend verifying gold.

1) Look for Stamps: 18K, 14K… or Numbers Like 750

Gold is often marked in two systems:

-Karat stamps: 10K, 14K, 18K

-Millesimal fineness: numbers like 750, 585, 417

Common meanings:

-750 = 18K (75% gold)

-585 = 14K (58.5% gold)

-417 = 10K (41.7% gold) 

If you see “750” on a piece, that’s a strong sign it’s in the 18K category.

2) Understand the Word “Hallmark”

A hallmark is essentially a mark that indicates metal purity and sometimes maker/assay details. Not every country uses the exact same hallmarking system, but stamps and marks are still one of the fastest first checks. 

3) Canada: Marking Rules Matter

In Canada, precious metals marking has specific rules about how items can be marked and described (e.g., quality marks should be accompanied by factual karat designations in many cases). 

What this means for you as a buyer:
Clear, correct stamping and honest descriptions are part of trustworthy selling.

4) Quick “Reality Checks” (Not Perfect, But Useful)

These are gentle checks—helpful, but not final proof:

-Magnet test: gold itself isn’t magnetic, so strong attraction can be a red flag.

-Weight/feel: real gold feels dense for its size.

But remember: some fakes can pass basic tests. The best verification is professional.

5) The Best Way: Professional Testing

If you’re buying high-value pieces (or you’re unsure):

-Ask the seller about authenticity

-Request documentation/receipt

-Get a jeweller to test (common methods include acid testing or XRF)

A reputable seller won’t get uncomfortable with honest questions.

6) Buying Smart: The “Luxury Checklist”

Before you purchase, ask:

-Is it solid gold or plated/filled?

-What is the karat? (18K / 14K / etc.)

-Is there a stamp like 750/585?

-Do you provide a receipt and clear description?

If the answers are vague, it’s okay to walk away.

Final Thought

Real gold jewellery is about more than shine — it’s about confidence. When you know what “750” means, when you understand karats, and when you buy from trusted sources, your jewellery becomes what it should be: beautiful, meaningful, and secure.
