Have you ever wondered if that piece of jewellery sitting in your drawer is real gold or just gold-plated? Whether you’ve inherited family heirlooms, found old jewellery, or are considering selling some pieces, knowing if your gold is genuine is the first step to understanding its value.
At Midlands Gold Buyers, we encounter this question daily from customers across Derby, Nottingham, and throughout the East Midlands. While professional testing is always the most accurate method, there are several simple tests you can perform at home to get a good indication of your gold’s authenticity.
Why Testing Your Gold Matters
Before diving into the methods, it’s important to understand why this matters. Genuine gold retains its value and can be worth hundreds or even thousands of pounds, while gold-plated items typically have minimal scrap value. Knowing the difference can save you from disappointment and help you make informed decisions about selling or keeping your pieces.
1. The Magnet Test – Quick and Easy
What you’ll need: A strong magnet (neodymium magnets work best)
How it works: Real gold is not magnetic. If your jewelry sticks to the magnet, it’s definitely not pure gold. However, be aware that this test isn’t foolproof – some fake gold pieces use non-magnetic metals as their base.
The process:
- Hold the magnet close to your gold item
- If it’s attracted to the magnet, it’s not gold
- If there’s no attraction, it could be gold (but needs further testing)
Important note: Some genuine gold jewelry may contain small amounts of magnetic metals like iron or nickel in the alloy, especially in lower carat pieces, so a slight magnetic attraction doesn’t automatically mean it’s fake.
2. Look for Hallmarks and Stamps
What to look for: Legitimate gold jewellery should have stamps indicating purity
Common markings:
- 9ct, 14ct, 18ct, 22ct, 24ct – British carat markings
- 375, 585, 750, 916, 999 – European fineness markings
- 9K, 14K, 18K – Alternative karat markings
Where to look:
- Inside rings and bangles
- Clasps on necklaces and bracelets
- Backs of earrings
- Hidden areas on larger pieces
Red flags:
- No markings at all (though some very old pieces may lack stamps)
- Markings like “GP” (gold plated), “GF” (gold filled), or “HGE” (heavy gold electroplate)
- Stamps that seem newly made on obviously old pieces
3. The Float Test – Using Water Density
What you’ll need: A glass of water and your gold item
The science: Real gold is much denser than most other metals, so it sinks quickly in water.
How to do it:
- Fill a glass with water
- Gently drop your gold item into the water
- Observe what happens
Results:
- Real gold: Sinks immediately and sits at the bottom
- Fake gold: May float or sink slowly
- Gold-plated items: Usually sink but may behave differently than solid gold
Caution: This test works best with solid pieces. Hollow jewelry may behave differently due to trapped air.
4. The Ceramic Scratch Test
What you’ll need: An unglazed ceramic plate or tile
How it works: Real gold leaves a gold-colored streak when scratched against ceramic, while fake gold may leave a black mark or no mark at all.
The process:
- Find an unglazed ceramic surface (the bottom of a ceramic mug works)
- Gently scratch your gold item against the ceramic
- Examine the streak left behind
What to look for:
- Gold streak: Likely real gold
- Black or dark streak: Probably not gold
- No streak: Could indicate gold plating over another metal
Warning: This test can damage your jewellery, so only use it on pieces you’re willing to potentially scratch. Always test in an inconspicuous area first.
5. The Skin Test – Watch for Reactions
What to observe: How your skin reacts when wearing the jewellery
Real gold characteristics:
- Doesn’t tarnish or turn green
- Doesn’t cause skin discoloration
- Remains bright and lustrous over time
Fake gold signs:
- Turns your skin green or black
- Tarnishes quickly
- Loses its color or shine
- Causes allergic reactions in sensitive individuals
Time factor: Wear the piece for several hours or days to see if any reactions occur. Real gold should cause no skin discoloration.
When Home Testing Isn’t Enough
While these methods can give you a good indication, they’re not 100% accurate. Some sophisticated fake gold can pass several of these tests, and some genuine gold pieces might fail due to their specific composition or age.
Professional testing is essential when:
- You’re planning to sell valuable pieces
- Home tests give conflicting results
- The jewellery has significant sentimental or potential monetary value
- You need accurate purity assessment for insurance purposes
