A guide to what jewelry stamps mean.
What does this jewelry stamp mean? This is one of the most common questions we get through Quora. You can fill in the blank as to what the stamp is. We will list them in a what is___ format, just as if we were answering a message. We have invested many hours of research in order to bring you this guide on the meaning of different jewelry stamps. We will start out with the most common stamps that we see and work our way through some more uncommon stamps on jewelry.
So what do jewelry stamps mean?
Jewelry stamps have different means but the three main things that are identified by jewelry stamps are-
The material the ring is made of
The ring maker
The location where the ring was made
What does a .925, 925 or ster stamp mean?
These stamps stand for sterling silver. This means the piece of jewelry should be 92.5% pure silver mixed with another metal, usually copper. Silver on its own is very soft and needs another metal added to make solid jewelry.
A common question that I get is “ I have a gold ring stamped 925, what does that mean?” Much to my dismay I have had a few people get very angry with my answer. The answer is this means that the base metal is sterling silver with gold plating. There is nothing wrong with this if you are wanting some jewelry made of high-quality metals at an affordable price. The issue will normally come down to was the person selling or gifting this item to you honest? I suspect that the anger stems from the answer being no.
Other common questions are what does 925___ mean. For example, what does 925nc mean or what does 14k KC mean. This is simply the symbol for 92.5 sterling silver (925) and the maker’s mark (nc). The 14k KC means simply 14k gold (14k) and the makers mark (KC). There have been thousands of maker’s marks, so if you need to know who the maker is, it will take some research to discover this.
I’ve also seen questions like what does 14k GP mean? This means 14k gold plated, but this does not give any information as to what the base metal is.
Gold is the same as silver in that it is much too soft on its own. There are several variations of gold mixes and these are what they actually stand for.

What does 10k stamp mean?
41.6% or 10 parts per 24 pure gold mixed with other metals, usually nickel, copper, zinc or silver.

What does 18k stamp mean?
75% or 18 parts per 24 pure gold mixed with elements such as silver, copper, and nickel.
What does 18c stamp mean?
Some countries use c instead of k for gold. So this still means 75% gold.
What does 24k stamp mean?
100% or 24 parts per 24 pure gold. This means no additives. While this is pure gold it is also very soft and tends to bend and scratch rather easily. This is one of the reasons it is rare to find jewelry that is pure gold.
As a side note, palladium is added to gold to make white gold. Also, Karat is usually stamped k, K, or KT and is different from Carat. Carat is for measuring the weight of gems and not metals.
Another common stamp on gold (especially from England) are essay marks. These marks are not made by the manufacturer but by the essay’s office to certify the purity. Each number stands for the percentage of purity of gold, platinum, and silver.
For gold, the stamps are 375, 585, 750, 916, 990 and 999
For silver, the stamps are 800,925,958 and 999
For platinum, the stamps are 850, 900, 950 and 999
Please refer to the photo to see what the stamps look like as well as the essay’s office stamp.
That covers the most common stamps on gold jewelry. There may be some other variations or even country marks such as Italy alongside these markings.

Are marks inside rings ever wrong?
The simple answer is yes. There are and always be scammers out there trying to rip people off. It has become more common for jewelry coming from China and other regions to have stamps that are not correct in order to pass of jewelry as real gold or even sterling silver. Always be aware of who you are buying from and make sure they have been around a while and have great ratings and / or reviews.
Another thing to watch for is mark manipulation. I have heard many stories on this. One that stands out in my mind is a ring marked 14kg. This ring originally was marked 14kgp meaning 14k gold plated but the p was polished out but there is no 14kg.
