Magnet test: DIY jewellery quality check

The magnet test is a popular DIY hack for spotting fake jewellery at home, but it has serious limitations - especially for diamonds, gold alloys, or luxury pieces. Here's the complete guide on how to test jewellery with a magnet, what results mean, why it falls short, and why Xazina's certified lab-grown diamond jewellery offers far superior quality assurance.

How the Magnet Test Actually Works

The test relies on basic physics: strong magnets attract ferromagnetic metals like iron, nickel, cobalt, and steel, which are cheap alloys used in costume or low-end plated jewellery.
What you'll need: A powerful neodymium (rare-earth) magnet-fridge magnets are too weak.
The method:

1. Hold the magnet 1-2mm from different parts of the jewellery (clasp, back, edges).
2. Watch for attraction: strong pull/stick = base metals; no reaction = likely non-ferrous.
3. Test multiple spots-plating can mask magnetic cores.

Pure precious metals (gold, platinum, silver, palladium) are diamagnetic or paramagnetic and show no visible reaction.

Interpreting Magnet Test Results

Key Reality Check: Real gold (even 22K/916) isn't magnetic, but many high-quality fakes aren't either-brass, copper, or tungsten plating mimics non-magnetic behavior perfectly.

Why the Magnet Test Completely Fails for Diamonds

Diamonds - lab-grown or natural - are pure carbon crystals with zero metallic properties. They never react to magnets.
Common simulants also fail:

• Cubic zirconia (CZ): Non-magnetic ceramic.
• Moissanite: Silicon carbide, non-magnetic.
• White sapphire: Non-magnetic corundum.

Bottom line: No reaction proves nothing about diamond authenticity. Magnet tests gold settings at best, ignoring the stone entirely.

Magnet Test Limitations in Luxury Jewellery

Even for metals, the test is unreliable:

• Gold alloys (14K-22K) contain copper/silver-non-magnetic even if slightly magnetic traces exist for strength.
• Platinum/rhodium plating on white gold: Non-magnetic surface hides any core.
• Fine jewellery clasps/prongs: May use trace magnetic steel for durability-false positive.
• Ignores purity levels: Can't distinguish 22K from 14K gold, or 925 silver from plated.
• No 4Cs info: Reveals zero about diamond cut, color, clarity, carat.

For plated vs. solid gold, magnets spot obvious fakes but miss sophisticated plating (1-5 microns thick).

The Right Way to Verify Jewellery Quality

For Metals (Gold/Silver):

• BIS Hallmarking (India): Mandatory logo + purity (916/750/585) + HUID number verifiable via BIS Care App.
• Acid Test/Nitric Acid: Professional jewellers scratch and apply acid-color change reveals karat.
• XRF Spectrometry: Non-destructive purity scanner used by reputable stores.

For Diamonds:

• IGI/GIA Certification: Full 4Cs report confirming lab-grown/natural origin, growth method (CVD/HPHT).
• Professional Loupe/UV Test: Experts check inclusions, fluorescence patterns.
• Thermal Conductors: Diamond testers measure heat conductivity (CZ/moissanite fail).

Why Xazina Lab-Grown Diamond Jewellery Beats DIY Tests

Xazina eliminates guesswork with science-backed verification:

• Every diamond IGI/GIA certified-verifies 4Cs, authenticity, CVD/HPHT origin.
• BIS-hallmarked solid gold/platinum (14K/18K/22K)-HUID-traceable purity.
• Transparency: Detailed specs, 360° images, warranties-no "trust us" needed.
• Ethical sourcing: Conflict-free lab-grown + sustainable metals.

Xazina vs. Magnet Test:

Skip home hacks-Xazina's lab-grown diamonds arrive with unbreakable proof of excellence.

Practical Home Checks (Better Than Magnets):

1. Weight/Feel: Solid gold feels heavier than plated for size.
2. Hallmark Stamp: Look for 916/750/925 + BIS logo.
3. Edge Test: File gently-solid gold resists scratching deeper than plating.
4. Vinegar/Iodine: Minor tarnish test (not for diamonds).

For real confidence, trust professional certification over hacks.
