When you're in the market for silver jewellery, it's important to understand the difference between sterling silver and silver plate. These two types of silver can look remarkably similar at first glance, but they differ significantly in composition, value, and longevity. Whether you're a jewellery enthusiast or a casual buyer, knowing how to distinguish between the two can help you make informed purchasing decisions and ensure you're getting exactly what you pay for.
What is Sterling Silver?
Sterling silver is a precious metal alloy composed of 92.5% pure silver and 7.5% other metals, typically copper. This composition gives sterling silver its durability while maintaining the lustrous appearance of pure silver. The "925" stamp you often see on sterling silver jewellery refers to this 92.5% silver content - and you can learn more about 925 silver over on our blog.
Sterling silver has been used for centuries in jewellery making and tableware due to its beauty and durability. It's a popular choice for those who want the look of silver without the softness and malleability of pure silver.

What is Silver Plate?
Silver plate, on the other hand, is not a solid silver alloy. It consists of a base metal, often copper, brass, or nickel, coated with a thin layer of silver through an electroplating process. The thickness of this silver layer can vary, but it's typically much thinner than the width of a human hair.
While silver-plated items can look beautiful and shiny when new, the silver coating can wear off over time, revealing the base metal underneath. This is particularly noticeable in areas that experience frequent friction or wear.
Key Differences Between Sterling Silver and Silver Plate
Understanding the distinctions between these two types of silver is essential for making informed jewellery purchases. Let's delve into some of the key differences:
Composition and Durability
Sterling silver, with its high silver content, is inherently more durable and long-lasting than silver plate. The solid silver composition means it can withstand wear and tear better, and even if it tarnishes, the silver content remains throughout the piece. Silver plate, while initially attractive, may lose its silver coating over time, especially with frequent use.
Cost and Value
Generally, sterling silver is more expensive than silver plate due to its higher silver content. However, it also retains its value better over time. Silver-plated items, while more affordable initially, may need to be re-plated as the silver layer wears off, potentially increasing long-term costs.
Weight and Feel
Sterling silver typically feels heavier and more substantial than silver plate due to its solid composition. Silver-plated items, depending on their base metal, may feel lighter or have a different weight distribution.
Methods to Identify Sterling Silver vs Silver Plate
Now that we understand the differences, let's explore some methods to distinguish between sterling silver and silver plate:
Stamps and Hallmarks
One of the most reliable ways to identify sterling silver is through its hallmark. Sterling silver is usually stamped with "925," "Sterling," or "Sterling Silver." Silver-plated items may be marked with "EP," "EPNS" (Electroplated Nickel Silver), or "Silver Plate." However, be aware that some counterfeit items may have false stamps, so this method isn't foolproof.
The Magnet Test
Sterling silver is not magnetic, while many base metals used in silver plating are. If a magnet sticks to your silver item, it's likely silver-plated. However, this test isn't definitive, as some non-magnetic metals can also be used as a base for silver plating.
The Acid Test
A nitric acid test can definitively distinguish between sterling silver and silver plate. When a drop of nitric acid is applied to sterling silver, it turns a creamy grey. On silver plate, it may turn green or a different colour depending on the base metal. This test should only be performed by professionals, as nitric acid is dangerous if mishandled.
Visual Inspection and Patina
Over time, sterling silver develops a unique patina - a thin layer of tarnish that many consider beautiful. Silver plate, when it tarnishes, may reveal the base metal underneath, especially in areas of wear. Look for signs of a different coloured metal peeking through, which would indicate silver plating.
Professional Appraisal
When in doubt, especially for valuable or antique pieces, it's best to seek a professional appraisal. Experienced jewellers and appraisers have the tools and knowledge to accurately determine whether an item is sterling silver or silver-plated.
Common Myths and Misconceptions
There are several myths surrounding the identification of sterling silver. For instance, some believe that all tarnished silver must be sterling, which isn't true - silver plate can tarnish too. Another common misconception is that all real silver is marked, but some antique or handcrafted pieces may not have visible hallmarks.
Final Thoughts
Distinguishing between sterling silver and silver plate can be challenging if you’re an amateur in jewellery, but armed with this knowledge, you're now better equipped to make informed decisions when purchasing silver pieces. Remember, both sterling silver and silver plate have their place in the jewellery world; Sterling silver offers durability and value, while silver plate provides an affordable way to enjoy the look of silver.
