Then, once armed with the knowledge of how to tell if earrings are real gold, discover where to shop quality gold earring designs for women. By understanding the following nuances, you can confidently select a piece of gold jewelry that stand the test of time.
Understanding the Basics of How to Tell if Earrings are Real Gold
How Karat and Gold Type Determine Value
Solid gold jewelry is crafted entirely from a gold alloy. Its karat number—such as 10k, 14k, 18k, or 24k—indicates the proportion of pure gold mixed with other metals for durability. The karat system, originally popularised by the Romans in 309 CE, uses the “solidus” coin as a gold standard – a legacy that remains pivotal today. This measurement not only defines the purity of solid gold, but also applies to the gold layer in vermeil and gold-plated jewelry.
While all three types of gold jewelry—solid, vermeil, and plated—contain real gold, the karat number significantly influences their value. Higher-karat gold, such as 18k or 24k, contains a greater proportion of pure gold, contributing to a richer hue and higher cost. Conversely, lower karats like 10k or 14k offer increased durability due to their higher alloy content, making them more practical for everyday wear.
Why is this important?
Understanding these distinctions is essential when determining how to tell if earrings are real gold and what you should expect to pay. Solid gold commands a premium price due to its high proportion of real gold, which as a rare and valuable precious metal significantly impacts that cost of the jewelry piece. In contrast, vermeil offers a more cost-effective option consisting of a gold layer over a sterling silver base, which is less costly to source. Gold-plated jewelry, while affordable, has the thinnest layer of gold and is less durable over time.
Buyers should carefully review descriptions of gold jewelry beyond the karat number. This knowledge helps avoid overpaying for plated jewelry or falling prey to sellers misrepresenting gold-plated items as solid gold. Identifying the type and purity of gold ensures you pay a fair price and make an informed purchase, whether you’re investing in an heirloom-quality piece or a fashionable alternative. See the table further below for a detailed comparison of gold jewelry types, including karats, durability, and value.
Solid gold
How to tell if earrings are real gold – what is pure solid gold, white gold, and rose gold?
Pure, solid gold is crafted using a specific percentage of pure gold (according to karat number) mixed with alloy metals for added strength. The karat system measures the purity of gold, with 24k representing the purest form of gold. The higher the karat, the higher the composition of pure gold. Their composition ensures that the colour, finish, and integrity of the gold last over time. Hence, solid gold jewelry, such as gold rings or engagement rings, maintains its value and offers superior longevity. Hence, they are ideal options for family heirlooms and investment pieces.
Gold jewelry, including gold pendants and earrings, made from pure gold, white gold, or rose gold. Specifically, white gold is composed of pure gold alloyed with white metals such as palladium or nickel. Whilst, rose gold is made by combining pure gold with a higher percentage of copper to achieve its distinctive pink hue. (As a side note, white gold should not be confused with platinum (link to blog post comparing the white gold with platinum). Platinum is a naturally white, luxurious metal known for its exceptional durability and rarity, often used for high-end engagement rings and fine jewelry.)
Gold is one of the least reactive metals, making it an excellent choice for hypoallergenic jewelry. Though, the presence of certain base metals can affect this (especially in lower-karat gold alloys like 10k or 14k). Unlike imitation gold pieces, solid gold jewelry retains its brilliance over time with minimal maintenance. Additionally, the surface of gold jewelry tends to remain free from oxidation or tarnishing, unlike other metals that may develop a black streak or visible mark with age.
A few tests for solid gold jewelry
Hallmarks are the most reliable source for how to tell if earrings are real gold. Gold jewelry is often stamped with markings like “10k,” “14k,” or “18k” to indicate its karat and purity. Furthermore, hallmark digits like “375,” “750,” or “999,” are used internationally to represent the gold’s fineness or purity. These numbers reflect the parts per thousand of pure gold in the alloy.
| Karat | Percentage of Pure Gold Hallmark | Hallmark (Fineness) |
| 24k | 99% (pure gold) | 999 |
| 22k | 91.6% | 916 or 917 |
| 18k | 75% | 750 |
| 14k | 58.5% | 585 |
| 12k | 50% | 500 |
| 10k | 41.7% | 417 |
| 9k | 37.5% | 375 |
Reputable jewelry stores may also offer a hallmark test to verify authenticity. For at-home verification, the magnifying glass test or liquid foundation method can reveal black marks or scratches inside the ring. Their presence signals that the piece of jewelry may not be solid gold or contains more base metals.
These simple tests are an effective way to distinguish solid gold from imitation jewelry, ensuring your investment is in genuine precious metal. See further below for a table with more types of tests for gold jewelry.
How to tell if earrings are real gold from its lustre
Real solid gold has a warm, deep lustre.
Gold’s density and molecular structure reflects a higher percentage of light more evenly. The higher the gold content, the warmer, deeper, and more intense lustre.
Therefore, gold’s structure produces a radiant, mirror-like reflection that is characteristic of gold. Conversely, base metals often have irregular or less dense atomic arrangements. Meanwhile, gold’s dense molecular arrangement ensures minimal scattering of light, resulting in a sharper and more brilliant lustre.
How to tell if earrings are real gold from its colour
Furthermore, the high density of gold enhances its natural ability to absorb and re-emit light within the visible spectrum, contributing to its rich and warm hue. This is why solid gold, particularly in higher karats like 18k or 24k, exhibits such an intense and deep colour compared to lower-karat gold or gold-plated items. In contrast, imitation gold is often made from brass or other non-precious metals. Imitation gold lacks this depth and warmth, appearing duller and less lustrous even when polished.
Gold-plated Jewelry
How to identify gold-plated jewelry from appearance
Gold-plated jewelry features a thin layer of real gold, typically about 0.5 microns thick. The layer of gold is bonded to a base metal, such as brass, copper, or sterling silver via electroplating.
Though, gold-plated jewelry lacks the durability and hypoallergenic properties, in addition to the colour richness that is characteristic of solid gold. However, gold-plated jewelry can exhibit a richer hue if plated with higher-karat gold, such as 18k or 22k, due to the greater proportion of pure gold in the layer.
Nevertheless, its lustre may still lack the depth and brilliance of solid gold of the same karat, as the underlying base metal and thinner gold layer affect its overall radiance. The higher alloy content in lower-karat gold (like 10k or 12k) or non-gold metals (like copper or silver in gold-plated jewelry) diffuse the light, resulting in a softer lustre. Hence, this leads to a duller appearance compared to solid gold. Furthermore, the gold layer may wear off faster, revealing the base metal underneath.
Additionally, the base metal (such as brass or nickel) can cause allergic reactions, especially for sensitive skin. Gold-plated pieces are often more affordable but are generally not as resilient as solid gold.
Price
Gold-plated earrings are typically the most affordable option among gold jewelry. Their price reflects the low composition of gold and the use of less expensive base metals like brass or copper. This makes them an accessible choice for budget-conscious consumers seeking a gold-like appearance.
Gold Vermeil
How to tell if earrings are real gold – vermeil
Gold vermeil is a notable upgrade in quality compared to standard gold-plated jewelry, offering a more refined and durable option. It features a layer of gold—typically 10k or higher—plated over a sterling silver base rather than a base metal like brass or copper. To meet gold vermeil standards, the gold layer must have a minimum thickness of 2.5 microns, significantly thicker than the 0.5 microns often found in regular gold-plated jewelry. This added thickness enhances its resistance to wear and tarnish, though it still falls short of the longevity offered by solid gold.
How to distinguish gold vermeil from gold-plated jewelry
Gold vermeil can often be identified by specific hallmarks, such as “925” or “Sterling” to indicate its sterling silver core, alongside karat markings for the gold layer, such as “10k” or “18k.” In contrast, gold-plated pieces may lack these stamps or display only karat numbers without reference to the base material.
In terms of appearance, gold vermeil typically displays a richer and deeper colour than gold-plated jewelry due to its thicker gold layer, especially in higher karats like 18k or 22k. However, it may lack the sharp brilliance and lustre of solid gold because of the underlying sterling silver and the electroplating process. For those seeking a balance between the luxurious look of gold and affordability, gold vermeil remains an exceptional choice.
Additionally, the base metal can cause allergic reactions, especially for sensitive skin. Gold-plated pieces are often more affordable but are generally not as resilient as solid gold.
Price
Gold vermeil earrings typically cost more than gold-plated earrings due to their thicker gold layer and sterling silver base, offering greater durability and a more luxurious appearance.
How to Tell if Earrings Are Real Gold: Types of Tests
Practical Tips for Identifying Authentic Gold Jewelry In-Store and Online
Understanding how to verify the authenticity of gold is essential for making informed purchases. Below, we outline the most effective methods to distinguish genuine gold jewelry from imitations.
For instances when DIY tests are impractical—such as in-store visits—the most reliable evaluations rely on tactile and visual cues. Observing the jewelry’s weight in hand, its rich, deep hue, and the characteristic brilliance of gold can help minimise the risk of overpaying for counterfeit or non-solid gold pieces. Similarly, when shopping online, look for clear indicators of authenticity, such as hallmark stamps and detailed descriptions of karat purity.
| Test Name | Method | What to Look For | Notes |
| Hallmark Stamp Test | Most gold items bear a hallmark stamp indicating karat markings or millesimal fineness. For instance: 24k or 999: Pure gold. 18k or 750: 75% gold. 14k or 585: 58.3% gold. Use a magnifying glass to inspect the inner part of the ring. | Authentic gold items will have a clear hallmark stamp indicating gold purity. | Some fake gold jewelry may have counterfeit markings, so combine with other tests for verification. |
| Magnet Test Scratch Test | Use a strong magnet to see if the piece is attracted to it. Scratch the gold item on an unglazed ceramic plate or black stone. | Genuine gold is non-magnetic and will not stick to the magnet. Real gold leaves a gold streak, while fake gold may leave a black or greenish mark. | Not foolproof, as base metals in gold-plated jewelry can be non-magnetic. Risk of minor damage to the piece; proceed with caution, especially for valuable jewelry. |
| Density Test | Measure the gold item’s weight in grams and volume in cubic centimetres, then calculate density. | Authentic gold has a density of approximately 19.3 g/cm³. | Requires precision scales and tools for accurate measurement. Ideal for solid gold jewelry. |
| Nitric Acid Test | Apply a drop of nitric acid to a small scratch on the jewelry. | Real gold will remain unaffected, while fake gold or gold-plated items may show a green reaction. | Use only on inconspicuous areas. Protective gear is essential for handling nitric acid. |
| Float Test | Place the jewelry in a cup of water. | Pure gold is a dense metal and will sink, while lightweight fake items may float or not sink fully. | A simple method but may not differentiate between gold-plated items and genuine gold. |
| Skin Test | Wear the earrings for an extended period and observe the colour of your skin. | Authentic gold will not cause discolouration or allergic reactions. | Effective for identifying potential base metals in gold-plated jewelry that may irritate sensitive skin. |
| Colour Changes Test | Check for any visible discolouration on areas that rub against the skin or experience wear. | Gold-plated items may reveal the base metal underneath as the thin layer of gold wears off. | Best for assessing frequently worn jewelry, especially in rings or earrings with exposed edges. |
| Lighter Test | Hold a flame to the jewelry for a few seconds. | Real gold will not darken, while fake gold or gold-plated items may show discolouration or melting. | Be cautious to avoid damaging valuable pieces or exposing base metals. |
| Vinegar Test | Place a drop of vinegar on the gold item. | Authentic gold will remain unaffected, while counterfeit gold may change colour or react. | A quick at-home test, though not as precise as professional methods. |
| Professional Appraisal | Have the gold piece tested by a professional jeweller using specialised equipment. | A jeweller can confirm gold purity and provide a karat breakdown. | The most accurate and reliable method for determining the authenticity and gold content of your jewelry. |
Comparison of Gold Jewelry Types
Solid 24k, 22k, 14k, 12k, 10k, vermeil and gold-plated
When evaluating gold jewelry, it is essential to consider the karat. Karat number determines the gold’s purity, durability, and suitability for various purposes.
Ultimately, choosing the right karat ensures your jewelry matches your lifestyle—whether for everyday wear or as a valuable investment piece. This knowledge also helps you avoid overpaying or falling victim to misleading pricing.
