The primary stamp for silver is 925, indicating it's sterling silver (92.5% pure silver), often seen with words like "Sterling" or "925/1000", while higher purity silver might be marked 950 (Britannia silver) or 999 (fine silver), but you'll also find maker's marks, city marks, or historical symbols like a lion passant for British silver, all detailing quality, origin, or age.
Standard Mark - this mark denotes the standard of metal, eg. 925 for sterling silver, 375 for 9ct gold. Assay Office Mark: The Anchor symbol is the mark to show the product has been hallmarked at Birmingham Assay Office.
Genuine sterling silver pieces often bear specific markings or 'hallmarks' that serve as evidence of their authenticity: in particular, look for a stamp marked as '925', 'Ster', 'Sterling', or 'Sterling Silver'. The '925' hallmark is particularly significant, referring to the 92.5% pure silver content in the piece.
There are 5 standard marks found on British Silver:
800 silver contains 80% pure silver and 20% other metals, while 925 silver, also known as sterling silver, contains 92.5% pure silver and 7.5% other metals. This means that 925 silver is more durable and resistant to tarnishing than 800 silver.
Many fake or low-quality items carry the “925” stamp to mislead buyers. These items may be silver-plated or made from cheaper base metals like brass or nickel.
Magnet Test: As we've established, silver does not stick to a magnet. If your jewelry does, it's likely not real silver.
One of the most popular methods of determining whether silver jewelry is real involves examining the item's hallmarks. Sterling silver items typically bear the mark “925,” indicating the 92.5% silver composition. Fine silver, the purest form, is stamped with “999,” reflecting its near-total silver content.
You might have seen "925" stamped on rings, chains, or earrings—that's your mark of quality. If you're buying wearable silver, this is usually the best option. Also known as Britannia silver, this grade contains 95.8% pure silver, with the remainder typically being copper.
Use A Magnet
See if the metal reacts to a magnet. Precious metals such as silver, gold, and copper are not magnetic. If a magnet is strongly attracted to the metal, it is not pure silver.
Yes, 925 gold is pawnable, but you won't get nearly as much as you would from solid gold.
Silver hallmarks comprise four main elements to tell you this: the town mark, the date letter, the maker's mark, and the lion passant. During the period between 1784-1890 a duty was placed on gold and silver, leading to the introduction of the duty mark.
Silver is a chemical element with symbol Ag and atomic number 47.
Sterling silver and silver look exactly the same, and if you have silver jewelry, it's most likely sterling. The best indicator is the marking, or hallmark, stamped on in small numbers or letters. Sterling silver will have a 925 or STER, and fine silver will have a 999 or FS.
It May Well Look Silver…
For starters, many antique silver pieces were gilded – this means that a very fine layer of gold is applied, changing the colour, appearance, and quality of the item. Silver also corrodes over time, and older pieces can often be tarnished dark brown or black in colour.
The “Ping” Test
Silver has a distinctive acoustic resonance, producing a clear, sustained ring when struck. Gently tap the silver item with another metal object and listen to the sound it produces. Genuine silver should make a high-pitched, long-lasting ring. Base metals will produce a dull, short sound.
Hallmarks that say "plate," "electro-plate," "EPNS," or anything other than "925," sterling," or "800," are not actually silver. Anything that is " German silver " is also not silver at all, but an alloy of nickel and copper.
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.
To test silver with vinegar, mix equal parts of white vinegar and baking soda in a bowl and stir until the baking soda is dissolved. Then, dip a clean cloth or cotton swab into the mixture and apply it to the silver object. If the object is real silver, the mixture will cause a reaction that will bubble and fizz.
Silver has a higher density than other metals, so it should be heavy for its size. Although you may have genuine silver, if it weighs lower than similarly-sized silver pieces, it may be because it is comprised of silver alloys rather than sterling silver.
Does 925 Italy mean the chain is real silver? Yes, but it's not pure silver —it's sterling silver, which is an alloy made of 92.5% silver. Always verify authenticity before purchasing.
