Q. Hi,

Could you please give me some insight as to what "18.PLO" inside a white metal ring could be.

Thanks, Karin

Q. Hi. I bought a gold 14k ring for my wife with 3 sapphires and 2 diamond stones. Inside there is an engraved marking -- it looks like HI namdar or HI namdax? too small I don't know what does it mean. I hope you can help me. Thank you and regards.

Q. My sons found a ring digging outside. It was covered in mud, but cleaned up nicely. Its garnet surrounded by ten diamond stones. Is marked ga in the golden band. All I can find online is ga is a possible m makers mark. Could this be of any value. The gold tone seems flawless for the condition it was found.

A. Hi Joy. All we can do is guess whether the garnet, the diamonds, and the gold are real whereas any jeweler will probably tell you in seconds. My guess is that it is costume jewelry and the ga means garnet.

I have an old ring that looks like silver. It is marked with A.19 and 900. Do you know what these could mean? Thank you.

Q. I have a claddagh ring that has printed on the inside made in Ireland, but also has two markers I have no idea what they mean. One of them are the letters O C in a bolder type font, the others are in small boxes and appear to be the letters H.G.R. what does this mean??

Q. I have a ring that has 925 on the inside as well as the c copyright mark along with the word "thailand" on the inside of the band. The ring has 6 large stones that appear to be sapphires along with small black stones in the middle. The ring appears to be old but is very beautiful.

I would like to know what the inside markings mean and if this ring could possibly be Thailand Sapphires? Any information is greatly appreciated. Thanks!

Q. I have a ring that is the color of either silver or white gold. It has a 14K symbol on one side of the inside of the band and then it has Q.Q on the other side. The stones are clear, and look like they could be real. What does the Q.Q mean? Does this sound like a real ring?

Abbie Watkins
- Fort white, Florida, USA

October 18, 2012

A. Hi Abbie. Assuming the 14k mark isn't counterfeit, and it's probably not unless it has a shady history, yes, it's real 14k gold.

Stones that aren't huge and aren't diamonds aren't, to my knowledge, worth a bunch though.

Q. Hi there, I have a gold ring with the markings B1701 on the inside and it also has these scratches. Three slanted lines one way and three slanted going the other way. both markings are on the inside. I can't find what they mean?

thanks sara

Sara Blum
- Canada

November 28, 2012

A. Hi Sara. When you say gold, I guess you mean "gold color" or "gold tone"? If it doesn't have a karat mark it's probably not gold. If it doesn't have a "sterling" or ".925" mark it's probably not silver. If you send a photo of the markings it's vaguely possible that a reader may be able to identify the maker, but it's probably just one among hundreds of thousands of styles of costume jewelry. Look up the trademarks for Silpada and see if their 3-prong arrowhead is the scratches you are describing. Good luck.

Q. I was given a ring for Christmas and noticed inside the ring there is a "14K" imprinted and the letter "p", the star symbol and the letter "m". I was wondering what they both mean.

Kim Ingram
- Canal Winchester, Ohio, USA

January 10, 2013

thumbs up sign Folks! 14K means 14/24's gold. If you include a good photo of the hallmark there is maybe a very slim chance of a reader pointing you in the right direction towards what the hallmark means. But there are hundreds of thousands of hallmarks if not millions, and a verbal description of a hallmark is a waste of bandwidth; millions of readers have seen these pages over the last 18 years, and in all that time not a single reader has ever hazarded a guess from a verbal description of a hallmark :-(

Q. I am thinking of purchasing a ring that has this stamp inside. I tried to send a photo but I do not have outmail capabilities ;(.
But it says 925 P "star" M. I am told that it is silver plated. My question over what?

Cindy Skiba
- Mpls, Minnesota, USA

January 18, 2013

A. Hi Cindy. If it's marked "925" that indicates it is 92.5 percent pure silver, i.e., "sterling silver". It is possible that it is solid sterling silver and still has silver plating on it, because the silver plating could be 100% pure silver to deter tarnish, or the plating could be rhodium for the same reason.

It would certainly be misleading and absolutely illegal to stamp it 925 if it is not solid 92.5% pure silver.

Q. My wife bought a ring with the letters "9 ct oc" could you please tell me what this means, as she paid 180 euro for it but got a value on it from another jeweler who said it was worth only 60 euro. It's a white gold ring; the second jeweler said it was a second-hand ring sprayed with rhodium. Thanking you for your time. John

john noctor

February 12, 2013

A. Hi John. The symbol for purity of gold is Karat, Kt, or K.
Carat or "ct" refers to the size of a stone. So why a ring would be marked "9 ct" is a mystery, but indicates that it might be a fictitious marking. The second jeweler didn't comment on that!? The "oc" is probably the designer, and there are a million.

If it is 9 Kt gold, it's 9/24 pure, 37.5%. So multiply its weight by .375 by the current price of gold and you'll have the intrinsic value.

Most white gold is rhodium plated, so that's no surprise. Nor am I shocked that one jeweler would only be willing to give you a third of what another jeweler sold it for. They are both in business, both negotiating against you on price, and who knows how long the first jeweler had to keep it in the showcase and pay the heating, lighting and rent before it was sold, or how long the second jeweler will have to. Say it's "objective value" is 100 Euro, and you paid 180 -- yes, that's a markup, but I don't think it's outrageous at all. Good luck.

Q. Hi Ted, thank you for your prompt reply. Just to say there are stones on top of the ring he said cubic. The second jeweller said it was an old ring but it was sold to my wife as a new one. There are no other marks stamped symbols on it, just the letters I told you about. Should there be? Thanks again, John

Q. I have this old Italian style men's 10K white gold diamond ring, inside is engraved with the following "10K" which is obviously 10 carat, beside that is "8.5" in which I assume to be the size of the ring, however what I'm puzzled about is the engraved symbol beside that in which appears to be of a diamond-like shaped heart form with an horizontal oval-like spin through the middle of the symbol ... any thoughts? Thanks so much! :)

A. Hi Fawn. 14K doubtless means 14 karat gold. We'd like to help with the rest but it's probably a maker's mark and hopeless (we've posted hundreds of such requests but there are an almost infinite number of makers, and most people naturally come to this public forum page to find out about their own not help others find out about theirs). Good luck.

Meaning of Marking "JC"?

July 29, 2013

Q. I had a ring handed down to me. It is oval shaped opal (I think opal anyway) with a band running across the top of the opal and holding a diamond. It also has 2 rows of diamonds on each side of the opal. I can't tell if the diamonds are some kind of black diamonds or extremely dirty (haven't had a chance to clean it yet). The marks are 925 (I know that means sterling) and "JC". I have looked everywhere and can't find anything with JC marks except one site that showed a bracelet with JC mark and it said "unknown victorian era maker" Does anyone have an idea what JC means?

Q. I have a wedding set that only has JC stamped inside. The rings are very big and has one large diamond (if real) and one small on each side. How can I tell if this is real, and what does JC mean?

Amanda Harper
- Atlanta, Georgia USA

June 2014

A. Hi Amanda. Any jeweler anywhere can tell you in 30 seconds flat if the diamonds are real or they wouldn't be able to last a day in business :-)

As for what "JC" means, it could be an "unknown victorian era maker" as Stephanie T says, but it could also be the initials of anyone in the world with those initials :-(

I know PAT likely means patent? But I looked around and couldn't find RKT or 1925 anywhere


Cassandra Mattice

Q. I have a ring; on inside of band it has the letter P, on the other side 925. Is P plumb for gold or the 925 silver?
It's not magnetic; it marks my skin when I wear makeup.
It doesn't turn in vinegar; I've looked on line I've seen plumb gold 925.
And silver -- any ideas?

Megan Harris
- Agassiz, BC, Canada

November 22, 2013

A. Hi Megan. Well, a "c" with a circle in it sounds like the ubiquitous "Copyright" symbol, but without a photo, it's hard to say. 14K is obviously 14 karat.

Although there have been no answers to the last 10 questions, if you send photos there will at least a chance. Good luck.

Q. Hi! I ran across a ring I bought 20+ years ago at an estate sale. It is a hexagon shaped diamond engagement style ring. The inside of the band is stamped "10kt-P" on one side and "EW 3" on the other side. Can you tell me what these mean? If I saw correctly, in the earlier thread, you indicated the "P" means plumb, but what about the rest? Thanks so much!

A. Hi Christy. I am not a jeweller, have no training at all in it, and I'm only looking at pictures ... but my guess is that it's real but not especially valuable.

My reason for believing it's real, besides the general look of it, is a question about a white gold ring, marked "Cosmic" in cursive, at

My reason for believing it's not particularly valuable, besides the general look of it, is rather similar looking items for sale on Ebay.

Ky Marie

February 15, 2014

Q. I recently received a ring set from my mother that was bought by my father from an estate sale back in the 1980's. They both appear to be white gold, one with 5 small diamonds to serve as the wedding band, and the other has one larger diamond in the middle with two small diamonds on each side to serve as the engagement ring. On the inside, both say DUVAL on one side and 14KPAT FL-E on the other. I have tried researching Duval but haven't come up with anything. I would like to know if Duval is the company that made the rings? What does the coding "14KPAT FL-E" on the other side of the rings mean? And also, can the code indicate the rings' age?

Cailey Horn
Hobbyist - Clayton, Georgia, United States

February 2014

A. Hi Cailey. 14K means 14 karat. PAT probably means a design patent -- just basically that you can't copy the look of the ring.

"Duval" and "FL-E" are probably as good as meaningless because there are thousands upon thousands of jewelry makers and combinations of letters applied like this and, as your researches showed, Google will get you nowhere. You need to take it to a jeweler to verify that it's 14K gold, and to have the diamonds evaluated.

Platinum Ring over 100 years old with 2/3 caret Emerald and Diamond Chips on side

March 25, 2014

American Jewelry Manufacturers
from Abe Books


Q. Hi. My name is Helene. I was recently given one of my Grandmother's rings. It has to be over 100 years old and on the inside it's stamped platinum and then there are 3 Capital K's engraved on the inside and then it seems that it was re-engraved later with a 7 over the first K, 6 over the second and 3 over the last K. It also has the numbers 216 or 276 engraved on the inside, but across from the engraving letters/numbers. It has a fairly high setting with a rather beautiful 4 prong which splits into 3 each, making the top of the emerald look like it's being held by 12 prongs. I have taken it to several very good Jewelers in my area and none of them could tell me what any of it meant. They all said they had never seen something like that before. Two of them did offer to buy it, but I'm not selling, just extremely curious now to find out what the engravings mean. It's become a quest to me. Is there anyone that could help me and solve my mystery? It really is starting to drive me a bit insane. Thank you to all who have taken the time to read this and hopefully have an answer for me.

What does 21cp mean?

March 28, 2014

Q. I have a gold pendant that's really unusual looking has the mark 21cp. I took it to a jeweler to have it checked out and it is indeed 21k but why is it stamped 21cp?

K Ferrara
- newnan, Georgia USA

March 2014

Hi K. I know that "kp" means "karat plumb" and this might possibly be a variation on that. When jewelry is made, it may require solder or this and that which adds slightly to the weight. So if it started out 21 karat, it really isn't quite 21 karat anymore when you add the weight of the solder. As long as this additional weight is small, the jeweler is allowed to round up and still call it 21 kt. The "plumb" means it's still a full 21 karats even if you include the solder, etc., i.e., if you weigh it, at least 21/24ths of the total weight is pure gold.

Elna Potgieter

April 2014

A. Hi Elna. Unfortunately "JH" means nothing and the color means nothing, so no one has any basis at all upon which to speculate. You need to go to a gold dealer and find out what you have if you are interested in its intrinsic metal value more than its sentimental value. Good luck.
