If you’ve ever looked closely at a ring or maybe the clasp on a necklace, you may have noticed a three digit code stamped into the metal. Also, sometimes called a hallmark, these numbers stamped onto your silver jewelry or gold jewelry can differ, but one hallmark you’ll sometimes see is an 825 jewelry stamp.

What Does 825 Mean on a Ring (or Other Jewelry) Made From Gold?

You have some rings or maybe some other jewelry with an 825 stamp, and you’re pretty positive that the jewelry consists of gold — so what does the 825 mean?

Quote 1

Finding an 825 stamp on gold jewelry means that the gold jewelry in question includes 82.5 percent pure gold and 17.5 percent of some other precious metal. Gold marked with an 825 stamp is about equivalent to 19 karat gold. The different metals used within the gold can vary, but popular options include:

  • Silver
  • Copper
  • Nickel
  • Palladium

What Does 825 Stamped on Jewelry Made From Silver Mean?

Similarly, if your silver jewelry features an 825 stamp, it means that it’s made from 82.5 percent pure silver, with 17.5 percent of other precious metals mixed in.

Quote 2

Most silver is mixed with other metals to some degree, as pure silver can be pretty soft and subject to tarnishing. Adding other metals can make the silver more durable.

Popular metals to mix with silver include:

  • Copper
  • Zinc
  • Gold

However, note that if the silver jewelry has an 825 stamp present, the piece does not contain enough pure silver to be considered sterling silver. Sterling silver features a stamp of 925 or higher or a stamp that says “S Silver.”

What Does an 825 Stamp on Jewelry Made From Other Metals Mean?

jewelry stamps that you can expect to see as you trawl your jewelry boxTruthfully, you’re not likely to find an 825 stamp on jewelry made from other metals. An 825 mark on jewelry is not the most common type of hallmark overall, and both gold and silver jewelry often feature much more common marks.

What other jewelry stamps can you expect to see as you trawl your jewelry box? Here are a few that might come up.

A Purity Mark

The 825 stamp is an example of a purity mark. Still, there are many other purity marks, beyond the jewelry 825 meaning, that you might see on a piece of jewelry, letting you know to what degree a piece is “pure.” Sometimes, the purity mark might reveal that your piece is not pure at all — such as if a ring is gold plated silver versus fully gold or made from German silver, which contains no silver whatsoever.

More notable gold purity marks include 14K, 18K, and 10K, which indicate the gold’s karat, or purity.

Silver purity marks typically have three digits, which correspond to the percentage of real silver in the piece. For example, a 925 silver purity mark indicates that the piece is 92.5 percent pure silver. The 925 silver purity mark is one of the most common.

Ring Size

Sometimes, jewelers might stamp a ring with a single digit that indicates the ring’s size.

Gemstone Carats

A stamp with a decimal point followed by two digits could be a gemstone size stamp. These stamps let you know the size, in carats, of the jewel featured in the piece. The number might also be accompanied by a “CW” for “carat weight.”

Metal Type

Sometimes, rather than numbers, a piece of jewelry with a stamp featuring a series of letters, and these letters might indicate the type of precious metal used in the jewelry’s production. For example, “PLAT” and “PT” both stand for “platinum,” and, as mentioned, “S Silver” stands for “sterling silver,” as do “STG” and “STER.”

An Assay Office’s Stamp of Approval

Less commonly, an assay office will sometimes stamp a piece, indicating that it is authentic. The stamps will differ depending on where in the world the assay office is located.

For example, the Birmingham Assay Office uses an anchor stamp in the United Kingdom. Meanwhile, the national assay office in France uses an eagle stamp. Finland uses a stamp with a crown inside a heart, while Sweden uses a stamp with three crowns.

FAQs

How do I know that my jewelry stamp is correct?

If you purchased your jewelry from a reputable seller, you can likely rest assured that the stamps on the piece are correct. However, suppose you bought the piece from a secondhand seller or another, less-formalized route, such as at a thrift store. In that case, you may find the stamps less trustworthy. They can be forged and tampered with. Luckily, a qualified jewelry appraiser can verify your jewelry’s authenticity.

How do I find jewelry stamps on a piece?

Since jewelry stamps do not add aesthetic appeal to a piece, they’re often strategically placed in hard-to-see spots where the average viewer would not notice them. You can find jewelry stamps usually on the inside of rings, necklaces, or bracelet clasps.
