How to Identify Genuine 916 Gold: 5 Simple Tests You Can Do at Home
With gold prices reaching RM 528.42 per gram for 916 gold in Malaysia today (June 1, 2026), ensuring your jewellery is genuine has never been more important. Whether you’ve inherited gold pieces, bought second-hand jewellery, or simply want to verify your collection, knowing how to identify authentic 916 gold can save you from costly mistakes.
In this comprehensive guide, we’ll walk you through 5 simple tests you can perform at home to check if your gold is genuine. While these methods aren’t 100% foolproof, they’re excellent first steps before consulting a professional gold buyer or assay office.
What is 916 Gold?
Before we dive into the tests, let’s understand what “916” actually means. The number 916 refers to the purity of the gold:
- 916 gold = 91.6% pure gold (22 karat)
- The remaining 8.4% consists of other metals (usually copper, silver, or zinc) added for durability
- This is the standard purity for most gold jewellery in Malaysia
Compared to 999 gold (24K, 99.9% pure), 916 gold is more durable and better suited for daily wear jewellery like rings, necklaces, and bracelets. The slightly lower purity means it can withstand the knocks and scratches of everyday use while still retaining excellent value.
5 Simple Home Tests to Verify Your 916 Gold
1. The Magnet Test
This is one of the easiest and quickest tests you can perform.
How to do it:
- Find a strong magnet (a refrigerator magnet won’t be strong enough)
- Hold the magnet close to your gold item
- Observe if there’s any magnetic attraction
What to expect:
- Genuine 916 gold: Will NOT be attracted to the magnet. It may slide off or show no reaction at all.
- Fake or plated gold: Will show clear magnetic attraction, sticking to or being pulled toward the magnet.
Important note: While pure gold is not magnetic, some fake gold items use non-magnetic metals. So passing this test doesn’t guarantee authenticity — it just rules out the most obvious fakes.
2. Hallmark and Stamp Inspection
Malaysian gold jewellery is required by law to carry specific hallmarks. Knowing what to look for can tell you a lot about your item’s authenticity.
Common 916 gold hallmarks in Malaysia:
- “916” — The most common stamp indicating 91.6% purity
- “22K” — Alternative marking for 22 karat gold
- “K22” — Another variation used by some manufacturers
Where to look:
- Inside ring bands
- On necklace clasps or pendants
- On the back of earrings or bracelet locks
- On the inside surface of bangles
Red flags:
- Missing hallmarks on heavy or expensive-looking pieces
- Stamps that look stamped poorly or unevenly
- Marks like “HGE” (Heavy Gold Electroplate), “GF” (Gold Filled), or “GP” (Gold Plated) — these are NOT solid gold
3. The Float Test (Density Test)
Gold is a very dense metal — much denser than most materials used in fake jewellery.
How to do it:
- Fill a clear glass with water
- Gently drop your gold item into the water
- Observe how quickly it sinks
What to expect:
- Genuine 916 gold: Will sink immediately to the bottom. Gold’s density is approximately 19.3 g/cm³, making it one of the heaviest metals.
- Fake gold: May float, sink slowly, or hover in the middle of the glass.
Important: This test works best with solid pieces. Hollow jewellery or pieces with air pockets may not sink as quickly even if genuine.
4. The Sound Test
Gold produces a distinctive sound when struck or dropped, thanks to its density and softness.
How to do it:
- Hold your gold coin or flat piece about 6 inches above a hard, non-metallic surface (like a wooden table)
- Drop it and listen carefully to the sound it makes
What to expect:
- Genuine 916 gold: Produces a soft, dull “thud” or muted ringing sound.
- Fake gold or other metals: Produces a bright, sharp, high-pitched ringing sound (like a bell).
This test is particularly effective for gold coins and flat bars. For jewellery with gemstones or intricate designs, the sound may be affected by other components.
5. The Skin Discoloration Test
While not the most pleasant test, it can reveal a lot about your gold’s authenticity.
How to do it:
- Wear the gold jewellery for several hours, especially during activities that cause you to sweat slightly
- Remove the item and check your skin underneath
What to expect:
- Genuine 916 gold: Should NOT leave any discoloration, green marks, or black streaks on your skin.
- Fake gold or gold-plated items: May leave green, black, or gray marks on your skin due to the base metals (like copper or nickel) reacting with sweat and body oils.
Note: Some people’s body chemistry reacts strongly with certain metals, so a slight reaction doesn’t always mean the gold is fake — but it’s worth investigating further.

When to Seek Professional Help
While home tests are useful preliminary checks, they cannot replace professional authentication. You should consult a professional gold buyer or assay office when:
- You’re planning to sell your gold — Professional buyers use XRF (X-ray fluorescence) machines to precisely measure gold content without damaging the item
- The item has sentimental value — Don’t risk damaging heirlooms with home tests
- Home tests give conflicting results — If some tests suggest genuine gold and others don’t, get professional verification
- You’re buying gold — Always request a certificate of authenticity from reputable dealers
Where to find professional gold testing in Malaysia:
- Licensed gold dealers and jewellery shops
- Bank Negara Malaysia (BNM) registered goldsmiths
- Professional gold buyers in Negeri Sembilan, Perak, Melaka, Kuala Lumpur, Selangor, Putrajaya, and Johor
FAQs About Testing 916 Gold
Can fake gold pass all home tests?
Some sophisticated fakes can pass one or two tests, but it’s extremely difficult for fake gold to pass ALL tests convincingly. Combining multiple tests significantly improves accuracy.
Does 916 gold tarnish?
Authentic 916 gold does NOT tarnish under normal conditions. However, it can appear slightly dull over time due to dirt, oils, and environmental exposure. Regular cleaning with mild soap and water restores its shine.
Can I use vinegar to test gold?
Yes! The vinegar test is another home method — place a few drops of white vinegar on the gold. Real gold won’t react or change color, while fake gold may show discoloration or fizzing. However, this test can potentially damage delicate items, so use it cautiously.
How accurate are electronic gold testers?
Electronic gold testers (conductivity testers) are fairly accurate for basic screening but may struggle with certain alloys. For precise purity measurement, XRF machines used by professional buyers are the gold standard (pun intended!).
Conclusion
Learning to identify genuine 916 gold is an essential skill for any gold owner in Malaysia. With current prices at RM 528.42 per gram, even a small piece of fake gold represents a significant financial loss.
The 5 tests outlined in this guide — magnet test, hallmark inspection, float test, sound test, and skin discoloration check — provide a solid foundation for preliminary verification. However, for complete certainty, especially when selling valuable pieces, always seek professional authentication.
Remember: When in doubt, consult a professional. The small cost of expert verification is nothing compared to the value of knowing your gold is genuine.
