Buying jewellery can be exciting – but also confusing. If you’re unsure whether a piece is genuine, learning how to tell if jewellery is real can save you money and disappointment.

This guide shows you simple, reliable tests you can do at home to check metals and gemstones safely.

Check for Hallmarks

In the UK, genuine precious metals usually carry hallmarks. Look for tiny stamps inside rings or on clasps.

  • 925 – sterling silver
  • 375 – 9ct gold
  • 585 – 14ct gold
  • 750 – 18ct gold

You can verify marks using the
UK Assay Office.

Magnet Test

Real gold and silver are not magnetic.

  • If it sticks strongly → likely fake
  • If it doesn’t → still needs further checks

This test alone is not conclusive but helpful.

Weight Test

Precious metals are heavier than cheap alloys.

  • Compare with a known real piece
  • Lightweight jewellery is often plated

Sound Test

Drop gently onto a hard surface:

  • Real silver → soft ringing sound
  • Fake → dull thud

Only do this on durable items.

Skin Reaction Test

Wear for several hours.

  • Green/black marks → fake metal
  • No reaction → usually genuine

Note: sweat can affect results.

Scratch Test (Careful)

Scratch lightly on an unseen area.

  • Same colour underneath → solid metal
  • Different colour → plated

Vinegar Test (Gold Only)

  • Place drop of vinegar
  • Colour change → fake
  • No change → likely real

Rinse immediately.

Gemstone Checks

Fog Test

Breathe on stone:

  • Clears instantly → real
  • Fog lingers → fake

Light Test

Real diamonds refract light differently than glass.

Rustic & Handmade Jewellery

Handmade jewellery may not always carry hallmarks, especially small artisan pieces.
