How To Tell If Jewelry Is Real Gold: The Difference Between Solid Gold, Gold-Plated, and Gold-Filled Jewelry
Not all gold jewelry is created equal. Understanding how to tell if gold jewelry is real and identifying how to tell if jewelry is gold plated starts with distinguishing these three categories:
-
Solid gold: Made entirely of gold or mixed with small amounts of other metals for durability.
-
Gold-plated: A thin layer of gold applied over a base metal (brass, copper, or stainless steel).
-
Gold-filled: A thicker layer of gold (typically 5% of the item's weight) bonded to a base metal.
How To Tell If Jewelry Is Real Gold: The First Step—Look for a Hallmark
The hallmark test is often the fastest way for jewelers to learn how to tell if your jewelry is gold.
Understanding Karat Stamps and Purity Numbers
A hallmark is a small stamp indicating the gold’s purity. Common markings include:
-
24K (999) – 99.9% pure gold
-
22K (916) – 91.6% pure gold
-
18K (750) – 75% gold
-
14K (585) – 58.5% gold
-
10K (417) – 41.7% gold (minimum standard for gold jewelry in the U.S.)
Hallmarking Standards in the USA, Canada, UK, and EU
Different countries have specific gold hallmarking regulations, which play a crucial role in how to tell if jewelry is real gold:
-
USA: Regulated by the Federal Trade Commission (FTC), requiring all gold jewelry to be marked with purity.
-
Canada: Overseen by the Precious Metals Marking Act.
-
UK: Assayed and marked by the British Hallmarking Council.
-
EU: Varies by country but typically follows a millesimal fineness system.
What If There’s No Hallmark?
If a piece lacks a hallmark, it doesn’t necessarily mean it’s fake, but extra verification is needed.
Jewelry that is antique or worn down may have lost its markings. This is where testing methods (covered below) come in handy.
How To Tell If Jewelry Is Real Gold: Letter Markings That Indicate Gold Plating or Fake Gold
Common Letter Stamps and Their Meanings
If you want to know how to tell if jewelry is real gold, check for these markings—if any are present, the piece is not solid gold:
-
GP – Gold Plated
-
GEP (Gold Electroplated) – This means that the gold layer was applied using an electroplating process, where a thin layer of gold is deposited onto a base metal (like copper or brass) through an electrical current. Electroplated gold is very thin, usually less than 0.5 microns, making it more prone to fading and wear.
-
GF – Gold Filled
-
HGP / HEG (Heavy Gold Plated / Heavy Gold Electroplated): This indicates that the jewelry has a thicker layer of gold plating compared to standard gold-plated pieces. However, it is still not solid gold, and over time, the plating will wear off, exposing the base metal underneath.
Why Gold-Plated Jewelry Looks Like Real Gold
Gold-plated jewelry is often indistinguishable from real gold at first glance, making it difficult to determine how to tell if jewelry is real gold.
However, the plating wears off over time, revealing the base metal underneath. Retailers should always double-check inventory using professional testing methods.
A quick way how can you visibly tell if jewelry is real gold is by inspecting its color—real gold maintains a consistent tone, while fake gold may show discoloration over time.
How To Tell If Jewelry Is Real Gold: Simple At-Home Tests
If you’re wondering how to tell if my jewelry is real gold, performing a few simple at-home tests can give you an initial idea of authenticity.
The Skin Test: Does It Change Your Skin Color?
Real gold doesn’t tarnish or cause skin discoloration.
If wearing a piece leaves green or black marks, it likely contains base metals like copper or nickel.
The Magnet Test: Is Gold Magnetic?
Gold is not magnetic.
If a piece is attracted to a magnet, it likely contains iron or other magnetic metals. However, some fake gold items use non-magnetic metals, so this test alone isn’t conclusive.
The Float Test: Does Gold Sink or Float in Water?
Real gold is dense and will sink immediately when dropped in water. If it floats or lingers, it’s likely fake or gold-plated.
The Scratch Test: Using a Ceramic Tile to Identify Gold
Scraping gold on an unglazed ceramic plate should leave a gold streak. A black or gray streak suggests it’s fake.
How To Tell If Jewelry Is Real Gold: Scientific Tests for More Accurate Verification
The Density Test: How to Measure Gold’s Unique Weight
Gold has a mass density of 19.3 g/cm³. Using a scale and a graduated cylinder, you can measure the volume displacement of gold in water to determine its density—one of the most reliable methods for how to tell if jewelry is real gold.
The Vinegar Test: Spotting Fake Gold with a Simple Household Ingredient
Applying white vinegar to gold should cause no reaction. If it changes color, it’s fake.
The Nitric Acid Test: A Professional-Grade Chemical Reaction Test
Real gold does not react to nitric acid, whereas fake gold turns green or milky.
How To Tell If Jewelry Is Real Gold: Professional Testing Methods Used by Jewelers
Professional jewelers use advanced tools when determining how can you tell if jewelry is real gold without damaging the piece.
X-Ray Fluorescence (XRF) Testing for Precise Gold Purity Analysis
XRF machines use high-energy X-rays to penetrate the surface of the jewelry, exciting the atoms in the metal.
This process generates a unique fluorescent signal that identifies the precise composition of gold and other metals in the piece—without causing any damage.
Electronic Conductivity Testing: How to Tell If Jewelry Is Real Gold
Gold has a unique level of electrical conductivity, which means it responds differently to electrical currents compared to other metals.
Electronic gold testers work by passing a small electrical charge through the jewelry and measuring its resistance.
Since different gold purities (e.g., 10K, 14K, 18K) conduct electricity at distinct rates, these devices can quickly determine if the gold is authentic and what karat level it is.
This method is a fast, non-destructive way to verify gold purity in-store before purchasing inventory or reselling pieces.
Ultrasonic Testing: Detecting Metal Composition Inside Jewelry
Ultrasonic testing works by sending high-frequency sound waves through the jewelry and measuring how they travel and bounce back.
Real gold transmits sound waves consistently, while gold-plated or counterfeit pieces with mixed metals cause disruptions or irregular reflections.
This method is particularly useful for identifying hidden base metals inside thick jewelry items where other tests, like acid testing, might not be practical.
The Best Way How To Tell If Jewelry Is Real Gold: Consult a Professional
When Should You Take Gold Jewelry to a Jeweler?
If you're wondering how can you tell if your jewelry is real gold, taking it to a reputable jeweler is the best way to confirm its authenticity.
If the hallmark is missing, worn down, or appears suspicious—or if at-home tests give mixed results—a professional evaluation using specialized tests can provide definitive answers.
How Jewelers Authenticate Gold for Retailers and Wholesalers

How To Tell If Jewelry Is Real Gold: Tips for Retailers to Avoid Fake Gold in Inventory
Best Practices for Sourcing Authentic Gold Jewelry
Always request certificates of authenticity (COAs) and detailed documentation from suppliers to ensure the gold jewelry you purchase is genuine.
Reputable suppliers should provide third-party assay reports, hallmark verification, and karat certification to confirm gold purity.
Additionally, establish long-term relationships with trusted manufacturers and wholesalers who have a proven track record in the industry.
Working with Reputable Gold Suppliers and Manufacturers
Reputable manufacturers often have long-standing industry experience, strong customer reviews, and memberships with recognized trade organizations like the Jewelers Board of Trade (JBT) or the Responsible Jewellery Council (RJC).
Additionally, consider ordering small test batches before committing to large inventory purchases and use gold testing tools in-store to verify the quality of each shipment.
Training Staff on How To Tell If Jewelry Is Real Gold
Educate employees on how to check hallmarks, interpret letter markings, and perform simple gold tests like the magnet and scratch test.
Investing in hands-on training sessions with professional jewelers or providing access to gold testing tools can help staff quickly verify authenticity.
Additionally, establish clear in-store procedures for gold verification before accepting new inventory or purchasing second-hand jewelry.
A knowledgeable team helps prevent counterfeit gold from entering your store while reinforcing your reputation as a trusted retailer.
FAQs About How to Tell If Jewelry Is Real Gold
What Is the Easiest Way to Test Gold at Home?
The magnet test and vinegar test are two of the quickest and simplest methods for how to tell if jewelry is real gold at home.
Can Real Gold Tarnish or Rust Over Time?
No. Gold doesn’t rust or tarnish, but alloys may discolor.
Is White Gold Considered Real Gold?
Yes, white gold is real but mixed with palladium or silver to give it a lighter color. So, how can you tell if jewelry is real white gold? Check for hallmarks like 18K or 750, which indicate its gold content. Additionally, white gold is often rhodium-plated, so if the piece shows signs of wear revealing a yellowish tint underneath, it may need re-plating but is still authentic.
