This article will offer some tips on how to analyze and date antique jewelry.

Jewelry mirrors time, culture, and societal values. It reflects the taste and attitude of every period in history.

Luckily, there are definitely clues that can be used in deciphering how old your jewelry is. The older and more rare the piece of jewelry, the more valuable it will be. There are many more clues than just five, but these are quick and easy ways to help determine the age of your jewelry.

5 Clues to Help Identify the Date of Jewelry

1. Look at the findings and fittings on earrings.

2. Look at the findings and fittings on brooches.

3. Identify the material.

4. Use color to guess the time period.

5. Look at marks and hallmarks.

Clue 1: Fittings and Findings for Earrings

The invention of different earring findings will help date your jewelry. Jewelry findings are ready made pieces that jewelers use such as clasps, pin stems, hinges, etc. Fittings refer to the parts that can be custom-made for a piece.

This drawing shows the styles when they were introduced into the market. In order of date, the styles are named as follows: shepherd hook, image two is not named, kidney wire, screw-back (pierced), lever back, screw-back, post & butterfly, spring clip, and omega back.

Some of these styles are still made today. Thread stud earrings from 1890 are thicker in diameter and the nut is much heavier than those that are made today. Screw-back non-pierced earrings that were made in 1900 are still made today but they are not that common on newer pieces. Kidney wires were invented in the 1870s and are also still used today. The shape has been modified in the modern earring. Knowing the difference between all of these can be helpful when determining the date of your jewelry.

Clue 2: Fittings and Findings for Brooches

Most answers to understanding jewelry can be found by looking on the backs or undersides. Brooches have evolved over one hundred years, and the backs provide much of the information we need to date the piece. Again, this drawing shows the different types of clasps used on brooches or pins with the approximate date as to when they first appeared.

I have found that the trickiest thing about dating a brooch is not necessarily the kind of clasp, but an altered back. Look for any suspicious solder. Pools of solder would only be on a piece that has been altered or repaired. Another thing to look for are oval or round metal pads where the pin has been attached to the back of the brooch. This is also a sign that the piece has been altered.

When I first started buying jewelry I came across this unusual 14k gold-filled piece with a "c" clasp pin and a "hook" on the backside of what looks to me like a pendant. After some research I learned what it really is. Is this a brooch or a pendant? Have you seen this before? Take this poll and leave a comment.

Clue 3: How to Identify the Materials of Black Jewelry

Black jewelry can be found in abundance at flea markets, estate sales, and antique stores. Identifying what the black material is can make a big difference in determining when it was made and how much it could be worth. Black jewelry most likely made of one of the following: plastic, glass, stone, jet, gutta-percha, crepe stone, bog oak, and bakelite. There are ways to test each one of these materials to determine what it is.

  • Plastic is the most obvious of all materials to decipher. Plastic is very lightweight and you can tap it on your tooth to hear a "click" sound. Use your loupe to look for a mold line. A mold line will go all around the piece splitting in two.
  • Glass will be heavier and reflects light. Holding it in your hand will warm up the material.
  • Stone would remain cold if you held it in your hand.
  • Jet is as light as plastic, and hard and coal-like in material. This material is a type of fossilized wood that was first mined in Whitby, England in the mid 1800s. Carving jet was so popular that by 1870 there were more than two hundred jet shops in the small town of Whitby. Today, jet is in the seams of the cliff walls on which the town is built. Nowadays, it is illegal to mine for jet, which makes the material extremely valuable. To test for jet, rub the material on concrete or clay pottery. If a brownish black mark line is left, then it is jet. Just a note: jet breaks easily.
  • Gutta-percha can also be black. It is made from the sap of a Malayan tree. It was used primarily in the Victorian Era. Running this material under hot water will cause it to emit a strong burnt rubber smell. You can also rub a piece on your clothes to create friction. This material was introduced into England in 1841.
  • Crepe stone is another black material and is made of glass. It was introduced in 1883 by the Fowler brothers in Providence, Rhode Island. It was called English Crepe Stone. It has a very distinctive look. See photo show.
  • Bog oak is also another black material that is very easy to identify because it is oak wood that has been preserved in the bogs of Ireland. This jewelry is visually identifiable because of the Irish motifs.
  • Bakelite can be made black, but not all Bakelite is black. It is a phenolic plastic that was popular in the 1920s and 30s. A good test for Bakelite is to put 409 bathroom cleaner on a cotton swab and touch a small hidden area. If the cotton swab is yellow after touching the surface of the tested piece than it is Bakelite.

Clue 4: Using Color to Date Your Jewelry

The use of color gemstones and enamel correlates to architecture and decorative art of the times. For example, color in the Renaissance was almost gaudy, while the use of color during the Victorian Era was somber because the death of Prince Albert caused Queen Victoria to declare an extended period of mourning. After the Victorian Era, the period of Art Nouveau utilized soft and delicate colors with rich gold and silver metals. This was short-lived as the Art Deco era moved to the forefront with its use of bolder colors and geometric designs. A devil-may-care attitude influenced the look.

Color palettes dominated different time periods throughout history. Knowing which color gemstones were predominant at certain times in history goes a long way in helping to date a piece of jewelry.

Clue 5: Marks and Hallmarks

Hallmarks and markings are an important clue to help date a piece of jewelry. Most often these marks are hidden on the inside of a shank on a ring, the inside of a bracelet, or on the inside back of an earring. Using your loupe, you will often find some kind of mark identifying the jeweler, designer, retailer, or manufacturer. If you bring this to a jeweler, they may be able to date the piece based on the marks.

These marks can also make a tremendous difference on the value and collectability of the jewelry. Remember that the value is not always about the intrinsic value. The trademark can also provide information about when and where a piece was made. Good sources for this information can be found at: Researching Costume Jewelry History and the Online Encyclopedia of Silver Marks, Hallmarks & Makers' Marks

How I Analyze and Date Jewelry

The photo shown here is a sterling silver filigree camphor glass necklace. Dated about 1900, it features the "Order of the Eastern Star" in the center. The center star has five enamel points and with five different images. However, this piece is not all authentic. The open center panel has been taken off and replaced with this rectangular piece. You can see how it does not fit perfectly. Look on the outer edges and you will see the inconsistency of the space around it. On the back is a small screw that attaches this shape from the frame. I showed this to my jeweler. He said these pieces were designed so that different pieces could be changed out. It is bothersome that the center shape does not fit properly within the framed shape. This does affect the value and aesthetics.

I welcome any comments. Feel free to share your knowledge.

Hi I bought a necklace at a jewellery fair many years ago it’s pink stones they feel cold to touch and in between so many beads there are circles of what looks like small diamonds ( who knowes ) the fastener is a barrel shaped screw In and has made in France stamped on the fastener I am curious to know of this is costume jewellery Thankyou

PenelopePenrod on May 21, 2020:

I have just discovered this site today, and I am very impressed with the amount of information and knowledge here. I am also very excited to learn more about fashion, estate, vintage and antique jewelry, because my background in in designing and making one-of-a-kind fine jewelry in gold and platinum, and I am like a new baby here.

I'm retired now, and I am working with fashion jewelry pieces. One of the things I would like to know, is if there is a good place to buy broken pieces of nice older fashion jewelry. I have places I know of like thrift stores, Ebay,etc. , but would like to know if there is someone on line, or somewhere I wouldn't think about? I am using the pieces in collages, so they don't need to have pins, or earring backs, or pendant loops. It would help if they have all of their stones, but sometimes I can replace them, or work around the empty spot.

Also, does anyone know a good place to buy older stones of different sizes in one parcel?

I am so happy to have found this site, and the great information and knowledge found here!

Thank you for having a place like this for knowledge and information!!!

I found two 2 1/4" bracelets in a wall in Vancouver that was boarded over in 1960. They're 22k gold with lots of insets but not precious stones. Somebody hid these 60 years ago and apparently forgot all about them.

Peggy kocisko on May 02, 2020:

how could i get a piece appraised for its worth and time period

I have a silver two of them ones a heart with black ruby on it that opens and then I have a neck less with Ruby’s different colors and on silver chain the pendent opens from top with little diggling like hanging close to the pendent

calvinswishingstar on February 27, 2020:

Hello! I'm so glad to have found this site! I began seriously researching vintage jewelry a few years ago.

But, this is the first I've seen great information on figuring out the material of black jewelry.

And, I wish I'd known about the 409 & Bakelite. The only thing I'd seen before was an automotive paste that was $10 for a little tube that I have no other use for. I will definitely pass this on!

I have a question about your piece: sterling silver filigree camphor glass necklace. You say it's not all authentic, but then that your jeweler said the pieces were designed to be switched out. Because it doesn't fit perfectly, could it be authentic, but not meant for your pendant?

Can I mention a great vintage jewelry research & educational site? It's been fantastic & where I learned, with videos showing the real pieces' & their hardware, how to date by it. I'm sure you know what site I mean.

Thank you for making & moderating this site! The others I've found haven't been "running" for years. Except the wonderful Online Encyclopedia of Silver Marks... Which also covers silver plated & gold marks!

Elijah on January 10, 2020:

I have a cluster engagement bronze band silverplate multi cluster diamonds appears to be a 1 carat central piece and a surround in floral appearance of 20 other minature diamonds. (Theyre all mounted perfectly all reflect multicolours at differing times in the sun light) so maybe i have a costume piece from a victorian era? Im wanting a little help clarifying the piece that i have. If requiring a picture/photo then i can send through. Please assist its going to help greatly in dating my piece.

I have a beautiful brooch with a copper color backing. It has enameled and rhinestone flowers. It has a 51 or 57 stamped on the back. I am wondering what the backing might be. It is not tarnished at all. And curious about the number stamped on the back. Thanks.

Christine on December 13, 2019:

Thanks. I have a Victorian starburst pin with a C clasp and a round fastener. The pin itself is clearly not matching with the rest of the brooch. It makes sense that it would be a badly done repair.

Hi,

I was given a ring from an Italian aunt that belonged to her grandmother, not sure who gave it to her. It is silver or white gold and has a blue ceramic / glass face with 2 painted flowers ( millafiore?) surrounded by diamonds or crystals. There are 2 markings that appear to be letters and maybe numbers. I can’t really make it out.

It is designed to be both a brooch and a pendant.

VintageKate on April 28, 2019:

This is a great helpful article. Thank you to the long ago author. Could a follow up be organised and posted sometime please Administrators?? If at all possible? Thank you for your consideration.

Now.. commenters.. seriously??

To those who keep demanding their items be valued (the only applicable word) - please show some manners and common sense.

Firstly the author posted this article in 2016 .. she is hardly reading your comments daily.. and .. secondly ..it was an article inviting comments from readers NOT offering you free advice. And even then you are still not using the words ‘please’ or ‘tank you’. You have probably all scared her off unfortunately from ever writing another.

I write this comment as a stand against the poor manners so prevalent on social media these days.

Elizabeth Bryceland on April 11, 2019:

Your site is quite informative, and the video was well done. I have one question though, how do you tell what you actually have if the piece has no makers marks? The narrator said not all are marked. And it looks handmade, beautifully done, but plier marks left behind.

Kelly on March 04, 2019:

The pin with a hook could be for a watch?

Kelly Thomason on February 13, 2019:

I came across a few of my great grandmothers jewery from the late 1800’s to early 1900’s ,some costume and some that may be real. I have a great love and respect for anything old and I find these things very precious. I was hoping to send a few pictures if possible to see if you could help in determining what they are. I do hope that this was not a waste of your time. Sincerely ~ kelly. Kellythomason00@icloud.com

I have a Hedison Jewelry Co with the mark 'Hedy'. I can find sites showing their different marks, but I can't find info on WHEN that mark was used. Any idea

I believe your unidentified jewelry to be shoe duettes.

Madeline on November 14, 2018:

Very interesting! Wish I would have seen this years ago it would have been helpful. I love collecting beautiful jewelry. Nice video

coranmbeck on November 07, 2018:

The author of this article is merely giving readers advice and information on how they may date/identify their antique and vintage jewelry THEMSELVES. I'm not sure what is giving people the impression someone will be appraising their jewelry, or even answering their questions, as nowhere is it even suggested - much less stated - that these services will be provided. The reason you are not getting responses is because you are posting them in a "comments" forum. The author is asking for your comments on her article: was it helpful? What would you have liked to learn about?, etc. (i.e. she is asking for your help, not for you to be soliciting hers)

Nick Lord on November 03, 2018:

Hi.. i would like to send some pics for advise on a pair of earings. Is this possible? Thanks

Nick

CalvinsStar on October 16, 2018:

Very helpful information! But, I'm confused about something that is probably under my nose, so to speak. I see all these posts for help, but I don't see any responses.

My Questions:

1. The Clasp diagram is great! Is there a way to know how long each style was used? Only the 1920's indicates it's still used.

2. Does anyone have information on the designer or mark "Vero." I have 3 signed brooches & found less than a dozen more on resale sites, like Etsy. All I know is that Vero jewelry, I think only brooches, was made in the 1960s, as late as the 80s.

I have 2 Halloween brooches, which I haven't seen anywhere else: Frankenstein's Monster & an enameled ghost. That's right, kitschy! But fun!

As well as an enameled flower.

Thank you!

joy savarese on September 02, 2018:

I have a old ring that I bought for my sixth birthday. It had alternated stones of light and dark yellow stones the entire ring with these circle stones in atotal Val total shape with and adjusted band pending printed what is it worth???

Jacki O on September 02, 2018:

I have a signed YSL black runway cuff bracelet that I wish I could find someone to authenticate and date it. I had a local YSL store look at it, they couldn't but sent a picture to their Paris store and they couldn't either. Said its too old and they don't have data back to the early 60s to look at.? Were can I go that someone may know about it. It says YSL Made in France on the inside. I can take picture if you would like to see it.

Kathy eesteban on August 23, 2018:

I have a pair of screwback earrings the markings say Helzberg 14K on the actual earring itself, but on the part of where it screws it says Wells 1/20 12K and it says I am Loved, like the pins Helzberg is known for any idea about these earrings when they were made

Bradley Patrick on July 28, 2018:

I have what i believe is an old ring. Ita a birthstone ring with five stones and a silver band holding them in. The band is screwed in. If i sent a picture would you know when this style was used?

Kaleigh Barrett Bushnell on July 13, 2018:

At first i thought it was just a pendant/brooch as I have a few in my collection but after getting a pair of something eerily similar I now think it may be a shoe clip? Please someone comment if I’m correct...I’m dying to know now lol

Annie on July 12, 2018:

Just wanted to throw in my '2 cents' regarding that brooch/pendant at the top: I don't know the particular name for it, but I do actually own some because of ebay auctions. I'm pretty sure that I have seen them worn in in period movies set around the 1900's or so, usually on a longish, medium-heavy chain, and then pinned up to the side so that the chain is made to 'dangle' in some sort of artful display. (Or, maybe it's just as simple as to give the owner a choice: Hmmm, pendant or brooch?)

Kerre Huff on May 01, 2018:

My previous post described a brooch or pendant that could also be worn on a chain and it's heavy metal. It's not the thin open heart of Luchenbooth hearts rather solid with intricate designs and I can't find any kind of lettering on it at all. Can someone please help me

Kerre Huff on May 01, 2018:

I have a gold heart brooch with crown on top of it with what resembles a family crest of a crown with cross at top of crown on a green colored background and it has a c clasp

Mary on April 26, 2018:

Hey there - I have a pair of gold & diamond c. 1890’s stud earrings with post screw back. It is thicker than a modern post - even a screw back. To be able to wear the earrings I am going to have to get the posts replaced. How will this affect value? I’d really like to be able to wear them. I’ve also thought of changing over to a lever back - but this will alter them quite a bit.

Thank you for your advice.

cwpi on April 15, 2018:

I received an old brooch from a relative. I don't know who it belonged to or where it came from. Only when I cleaned it did I realize it was silver. It appears to have a clasp (unchanged) from the 1920's, has filigree and round silver discs and tear drops that dangle from it. I had a jeweler get the marks off the back for me: H within a circle then S088. I have researched this myself for days with no luck and am asking for help. There is no indication that anything on it was altered. Thank you!

naj on April 10, 2018:

Hi I have got an eternity gold ring that I think is very old .The marking says: N 825 or 625 C ( but reversed) and N.Can you help me to determine the age of my ring please ?

Cheryl White on November 08, 2017:

Hello, I have several pieces of jewelry that were my Mom's and probably my Grandmother's and great Aunt's. One piece, in particular, is a very large copper Indian vintage necklace that I need to find the value of. She also has several Ivory necklaces and some scrimshaw bracelets and ring, a star ruby and diamond ring, that dates back to the early 1900s, which has a very unusual shape and other valuable pieces. Where do I go to a reputable place who will give me an idea of what these pieces are worth. Any info you can provide me would be greatly appreciated. Thank you!

Mary on November 04, 2017:

The colors of the star are in the correct order, however, it is not facing the correct direction. The white ray should be pointing down. This also suggests that it is not original as an Eastern Star member would know the correct way it is worn.

Carol on November 04, 2017:

The colors on the star are incorrect but I don't know if it is just the way it photographed. The star should be blue, yellow, white, green, and red.

Liz on August 15, 2017:

Thank you for all the terrific information!

You have opened my eyes to a whole new world of fun collecting. What fun!

Carolyn C on August 11, 2017:

I have some jewelry that I know is vintage. I just don't know where to begin.

Pam on April 29, 2017:

Hi

I'm in the process of sorting out my jewellery that I have inherited from my two grandmas and my mum. Your website is proving to be very helpful. To give you an idea of time both my Grandmas were born in the late 1800s and died during the 1950s so your article is so helpful.

However are three items in my collection that I have no idea about. They are threaded on a piece of string . They are the same size (each are approximately 4 1/2 cms long, 2 1/2 cms wide and 1/2 cm thick); a curved almost diamond shape with curved edges and linked together with string that is threaded through the narrow ends. They feel like they are made of hardened glass or ceramic. However, they are covered with the most intricate beautiful minute coloured flower patterns on both sides, around the edges and even into the holes at both ends of each one. All patterns are different on each of these 'pendants' in blues, yellows, white, green and russett red. They look quite amazing and don't deserve to be tied together on a piece of string. They remind me of some Japanese prints. Can anyone help me work out what they are please.

Pree on April 24, 2017:

Hi I just purchased a camphor piece and cannot figure out if it's authentic, can anyone help?

Sharon on April 05, 2017:

Great article! Thanks for posting. Very helpful and well written.

karenm on June 14, 2016:

I think the unidentified piece of jewelry is a holder for a watch or decorative fob, which would hand from the hook at the bottom. Thanks for this resource.

Deborah Hileman on May 25, 2016:

I have a beautiful piece ( possibly pendant ) that has an unusual clasp on the back that I cannot identify. I have searched and searched but no one shows it.

I have several pictures that I can send if you are willing to help

thank you

Mina on May 23, 2016:

Thanks for posting this. I ended up getting a pair of earrings and could not figure out when the post was made. Your article is the first one I've seen on the web which actually helped me. Thanks again!

J Suzanne WM on January 24, 2016:

Hello. Loved your article! A few months back I purchased some rather non-descript earrings from a thrift store. I and my daughter love unique pieces. I almost passed them over until I noticed the screw on backs. I had never seen this before and thought surely they must be old. They are thin metal flowers and the other a simple circle. I think they are the screw-on for non-pierced ears. Very cool!

Mariana Fuzaro from São Paulo, Brazil on November 13, 2014:

Very helpful article. I enjoy antique jewelry.

anonymous on September 09, 2013:

I cannot add any knowledge I'm afraid as I have only recently started collecting. My comment is a question that brought me to this page which I know will be very helpful in my new hobby. I'm not sure how to word this question about a particular pair of earings so thst it can be understood but, I'll try. I found a pair of screw back vintage earrings that can also bd worn as pierced earrings. There are no discernable markings on the earrings with the naked eye. Has anyone seen this this before? They are not pierced earrings that have the screw on backs. I hope this was clear. Thank you

anonymous on August 08, 2013:

Really interesting video - well done. And the section on Black Jewelry was the best and easiest to understand that I have read so far. Thank you.

Wonderful lens, and very informative. Pinned to 2 of my boards: "collectibles" and "jewelry."

@anonymous: here is a search term for a great Ebay example, check out the back of the piece. Amazing-Georgian-Victorian-14K-Rose-Diamond-Brooch-Pendant. I would post the link, but the spam filter won't let me

The mystery piece is a convertible piece of jewelry called a brooch-pendant. It can hang on a chain or be pinned to the clothing. You can search on Ebay for similar pieces.

What a surprise to find my video showing here! Thank you for highlighting it. (If I had to do it over again, it would be of higher quality but, when I did the video, only smaller file sizes were allowed.)

Wow! This is so informative. And I thought it was going to be about dating jewelry instead of men! hee hee But really, I am dearly in love with historic pieces of jewelry but I am often very lost when trying to figure out when it was made or what it is actually made of.

The piece of jewelry above is a watch fob brooch. The hook on the back is to hang a watch chain from and the pin is usually pinned on the outside garment.

I have a pair of earrings that have .925 (C) M stamped on the backs. I've tried to find this online and have had no luck. Can you help? I have pictures of them. I know they were not made to be worn on the french wires they are on.

Thank you,

Melissa White

Great lens!

Diana Grant from United Kingdom on June 06, 2012:

I enjoyed reading this. My mother gave me some good advice - if you are having your jewellery valued, don't let it out of your sight - if they can't do it in front of you, and want to take it into a backroom, just leave: trust no-one because a good jeweller could change your valuable stone to a cheap one and replace it in the setting in a couple of minutes!

Angel Blessings for great information
