Vintage Jewelry Marks: Help for Dating Your Vintage Jewelry

Why Vintage Jewelry Marks are Important

Maybe you’ve just acquired some vintage jewelry from a family member or friend. Or you found some nice vintage jewelry at a yard or garage sale or at the thrift shop. Whether you plan to keep the jewelry as a family heirloom or would like to resell it, a knowledge of vintage jewelry marks will help you to identify and date it properly.

I often get requests from people asking for help with vintage jewelry they’ve acquired. Because it’s not possible to have a comprehensive discussion of how to identify and date vintage jewelry in a single article, this article is the first in a series, and will specifically address vintage jewelry marks. Future articles in this series will discuss how to date patented jewelry and jewelry without signatures and/or hallmarks.

Signatures vs. Hallmarks – What’s the Difference?

According to Lang Antiques’ Antique Jewelry University, the term “hallmark” refers to any stamps or marks on jewelry and usually includes one or more of the following:

  • Purity marks – indicates gold, silver, or other precious metal content
  • Maker’s marks – the firm or person responsible for guarantee of the purity mark (usually the firm or artist who manufactured the jewelry)
  • Dateletters – indicates when it was made
  • Town marks – indicates where it was made
  • Other marks (described below)

The photo below shows some of the most commonly seen vintage jewelry silver purity marks.

Vintage Jewelry Marks for Silver Purity
Marks commonly used in vintage silver jewelry

Purity marks for older silver pieces can differ from those commonly seen today. For example, most Sterling Silver Jewelry up until the 1940s era was usually stamped “STERLING” or “STER” or “STG.” The “925” mark did not come into common use until later. Some makers continue to use the “STERLING” mark in place of “925” even today.

Vintage jewelry from other countries may have European purity marks, such as “585” for 14K gold and “750” for 18K gold, as shown in the photo below.

A hallmark can also include other marks, such as:

  • Designer marks – used when multiple designers worked for the same firm
  • Tally marks – indicate the journeyman or artisan who actually created the piece
  • Retailer marks – a specific sales outlet, usually a large branded store
  • Duty marks – indicate that taxes have been paid on domestic pieces
  • Import and export marks – indicate that taxes have been paid or that items were exempt from taxes
  • Patent and inventory numbers – government or company issued numbers to protect and track jewelry designs

Vintage costume jewelry usually doesn’t have purity marks, but will often have a maker’s mark (commonly called the signature), and can sometimes have a retailer mark and/or patent or inventory marks. Patent numbers are especially helpful when dating older vintage jewelry, and will be covered in a separate article in this series.

Resources for Learning About Hallmarks

Antique Jewelry University: Lang Antiques features a section on their site named “Antique Jewelry University” with lots of useful information, such as this page discussing hallmarks: Hallmarks on Period Jewelry

925-1000: Described as the “Online Encyclopedia of Silver Marks, Hallmarks, and Makers Marks,” the 925-1000 site is the first place I go to research vintage silver jewelry marks. It includes silver marks from many countries and you can access it here: 925-1000 Silver Marks

Vintage Jewelry Marks: Changing with the Times

When learning how to date vintage jewelry, a maker’s mark (or signature) can be a big help, since most companies changed their signatures over time. As a general rule, signatures without a copyright symbol indicate the piece was manufactured prior to 1955. There are exceptions, however. Jewelry companies would often use up their supply of pre-stamped clasps and findings after switching to a new signature, so some pieces made soon after 1955 might not have copyright symbols.

A detailed study of vintage jewelry marks could fill multiple books, but to give some guidance we can use the Trifari company as an example. Trifari always signed its jewelry and was very diligent about protecting its designs. Prior to the change in the copyright law in 1955, the designs were patented. The most commonly seen vintage Trifari pieces have signatures from pre-1955 through the 1990s. In 2000 the company was bought by Liz Claiborne and production was moved overseas to create mass produced unsigned jewelry.

The photo below shows the various signatures you’ll find on Trifari vintage jewelry.

Robin Hawn

I have a 14 k gold necklace. On the clasp it has engraved the word butterfly. The clasp is a small hook with a weird looking butterfly. I have never seen this kind of clasp. Do you have any idea? Thank you, Robin


Are you sure that it is Mexican? There are a number of Southwest Native American marks that are doves and similar birds. If your sure it is Mexican, either bought there or marked Mexico, there are a number of different dove marks here as well. You would really need to show which mark it is, to get the correct answer.


You’ve shown my silver mark “silver” as number 4 in your silver examples, however, I don’t see a date or place of origin noted. Any information?


Jennifer Slone

Maker mark on a sterling silver heart locket that is an “M” inside of an elongated diamond with STER. above it??? Anyone?

Karen K

I have a piece of rhinestone jewelry that looks to be somewhat expensive. It is marked with 7-2 =. Can anyone tell me what this means? It is costume jewelry, I am sure, but it is nice a shiny with diamond shaped, baguettes, some small round and one larger round rhinestone in the center. It is a beautiful piece, just wondering what the marks on the back are for.


Great info- thanks for sharing! What do you call a tiny tag, or symbol attached to the jewelry? My grandma left me tons of jewelry and many pieces have a tiny gold key attached. Nothing matching the piece itself, clearly some kind of logo or signature, but have not been able to find any info or even figure out what it is for sure called? Kathy


I have a silver and marcasite bracelet from around the 1950s. There is a mark on the back of the piece PRK STERLING. Any ideas of the origin? I’m trying to research but not having any luck so far. The bracelet itself is made of 6 leaf shapes with openwork and highlighted with marcasite.

Thank you for any information you can provide

Shelley Neth

I have a vintage silver Fleur de Lis With small pearls from my grandmother (born 1903) that has the Mark 925/1000S. What does that mean, besides Sterling?


I have a pearl necklace with a gold flower clasp and inlaid sapphire. On the underside of the clasp is something that looks like an ornate crest with the letters NGM or NCM? Underneath the letters is something that looks like a rooster or other bird? It’s difficult to tell and I’ve looked everywhere and can’t identify the markings. If anyone can help… Thanks!


Good afternoon. I am trying to identify two antique jewelry marks and was hoping to get your assistance. They are both on rings, the first one the mark resembles -O-, with the circle having a dot in the center. It looks like the morse code symbol for the letter K. This is a simple ring with a solitaire clear glass stone. The second ring, the mark is on the outside of the band, it is a simple ring with an amber stone. The mark looks to have a vine or branch along with the letter O. Any information you may have would be greatly appreciated. Thank you for your time. Regards,


I have an oval locket that was my mother’s. It’s gold (?) with a flower design on front and black inlay and what looks like a fluer de lis on the back. Inside is not smooth, but looks like tool marks that smoothed it out. Inside the right portion is an XVIIII, scratched into the gold. XVIII = 18, so XVIIII should = 19, but 19 is actually XIX. I haven’t been able to find anything resembling it in order to help identify it or determine its value.

It comes with a heavy chain, with each link engraved with a pattern. It doesn’t clasp in back like modern necklaces where the clasp is hidden at the back of the neck, but clasps near the locket itself.

Can anyone help, or point me in the right direction? Thanks.

I have a lovely two tone brooch, a cornucopia with wheat coming out of it. The cornucopia is goldtone and the wheat is silver tone. The two sections are riveted together. The one mark is a number inside a rectangle 48498. I have never come across this before and sites like illusion jewels are of no help as they only use the alpabetical list. Can anyone help?


I have a brooch with the signature JASPER on it. I can’t find anything about it.
Can anyone give me an idea of where to start? Google only pulls up Jasper the stone.


Hello, Christine, this is Sharon. I have a polished-back CROWN TRIFARI bangle; the TRIFARI mark is followed by the letter “M” — I’ve never seen this before and i”m confused by it. Any information for me at all? I’ve been searching all over…

Sandra Drane

tks for the info…really helped..i have a few older pieces that has marking on them just says Pend..what does this mean? tks in advance.


I have a few pieces that I am having trouble identifying. One is a ring. The inside of the band says,
1 over 40 (there is a line between), 14K, Shank, R.G.P. >U< (the <'s are actually arrows), Made In USA.
There is a Princess stone set in a decorative gold ? and there are two smaller diamonds on each side set in silver settings.

The next piece is a necklace which has LJA10K on the clasp and is two separate pieces held together with a tiny jumper. Both piece has a tiny pearl and the other is a small diamond.


Lovely jewelry designs. For Victorian Jewelry online shopping Read customer reviews, they have a lot to tell about the quality of product. Plus you will find out if the website has forged the review and it is actually hustling the customers.


I have a 10K old quality gold ring that looks to be old with what looks like a French female bust (not the cameo bust)on a reddish stone… Etched inside of ring, are the markings of SK inside diamond… Any info would be helpful… Thanks

Have a silver shell brooch that is signed but can’t make it out, it appears to be “Gaglee Cme Cme” but can’t find anything. Any help?

Hi. I’ve clicked through most of your cyperlinks – very thorough! But I did not find the mark I’m looking for. I have matching vintage brooch and earrings.
They’re marked Sterling V.A
The A does NOT have a period after it.

Any thoughts? Thanks for your help.
