    Vintage Bracelet Marking
    Can anyone tell me what this marking means. While familiar or able to locate many jewelry markings this is new to me and am thinking about purchasing. All I know is that this a vintage piece, I suspect the 60s , but really not sure and it is about 1 1/18 wide and 7.5 inches long with safety clasp and insert closure. On the inside closure there is a marking which reads "CT18750". Any information available would be appreciated. Thank you.

    All right. DO NOT TRUST ME on this. I just pieced together what I found online, so who knows if it's actually so.

    CT most likely stands for carat (as in gold) and the 18 after it means 18-carat gold. The 750 after the 18 signifies that it IS 18 carat gold. I know that's confusing, but here's more information on 750:

    I hope this helps you!

    Good luck.

    Wow. It would be wonderful if this os so. I did buy it but as vintage costume piece figuring it was likely gold filled or plated. It is a very large and heavy piece. I assume CT was the maker's mark as the CT stands alone and below it is 18750 (all of this is incorporated in a box the shape is ; wow, can't believe I forgot the name of the shape. Top line is shorter than bottom and two side lines extend to each end point of bottom line at an outward slant. I will bring it to a jeweler based on your response and get back to you. If this should be gold, I will be sending you a thank you gift! Seriously, and thanks for going out of you way, it is sincerely appreciated Funny I have that sight saved and just never even assumed this could be real gold. We will find out. Good luck to both of us and thanks so much again. It does look like pure 18 Ct gold. :)

    You're so welcome! I'm glad I could help.

    Just so you know, though, many, many people can fake gold REALLY well. I'm glad that you'll take it to a jeweler. They'll be able to invesigate further.

    By the way... I think you're looking for trapezoid?

    Yes. Thanks.. . Let you know and I am aware of how well it can be faked. Hopeful.. . There are a few wear spots. Upon closer examination and following your suggested possibility, it wears like real gold. I may not be able to get to jeweler to next weekend so don't think I forgot you!

    Hi, Ct 18750,may be a European mark for 18k Gold, it's numeric 750 being 3/4 or .75% Gold.
    It may be white or yellow or a combo of both.

    How much do they want for the bracelet?

    Is it solid or hollow?

    Is this the only stamp on it?

    It may be a manufacturers stamp also.It may be a scam stamp also.Trust me I've seen too many scam stamps on plated jewelry,Stamp is not to be trusted!!

    Most American jewelry is (Karat)stamped 10k,14k,18K, Ct is normally associated with Stone weights named after the Carob seed which is uniform in weight--before the invention of the ct. scales used today.

    Doe's the owner know what it's metal content is?

    The only way to know is with a nitric acid test. Sratch and apply acid,green and bubbly not gold, no reaction -test further-

    Scratch on a test stone only reveles the top layer of metal,go beyond a simple light scratch.

    It may be gold filled or plated,even if you have to pay a jeweler to test it ,it's worth it.
    If it's real and he makes you an offer to buy or sell ,be restassured there is profit to be made.
    I have 23 years in jewelry business, Master Jeweler/Gemologist store owner Custom Designer.
    Antiquity is 50 years for jewelry.

    Hope this helps.

    Thanks so much everyone. I brought it to a jeweler who said 18750 inidicated 18K etc.; however, it was not, of course! I was told they did not even have to test it they could see with their eyes it was wearing in places. I finally did notice a spot on the safety catch where it was in fact weaing a bit, but that was the only place I could see, even with glasses! So it is just a vintage piece of jewelry. Well made as it is, it is not gold. I will put in my box of "not thrilled about" and one day I hope to start a little business on e-bay or somewhere and recoup my losses from some of my less than practical purchases. It has been a pleasure and nice to find people will take time to help. I am off to read a few and see if I can personally assist anyone. Thanks again.

    Thanks for the information. It's unfortunate for you that it isn't real gold, but it's good to know that there are people who would do such things.

    This could JUST be a manufacturer's mark. CT is NOT used to signify gold quality, KT is short for "karat", which is gold fineness. CT is actually short for "carat", weight of a diamond or gemstone. 750 IS used to signify 18k gold... but I doubt that is what the mark on your bracelet is. I hope this helps!

    Well I now know it is not gold as I took it to a jeweler myself. It is very heavy. I know nothing about it other than it is not gold. I have no idea about "appraisals in UK" however I think you need to find someone who is into vintage jewelry as this is likely either gold plate or gold filled and since vintage a regular jewler would likely not be able to assist. Let me know if you get any more information and sorry for the delay in responding. I only check may email once or twice a week. Have a wonderful week.

    Did the jewlery you took it to offer to buy it from you "real cheap"? If he did, he might have wanted to scam you out of a real 18kt piece, especially since he didn't test it in any way but visually. Experts usually can recognize fakes on sight and feel, and if you know and trust your jeweler, great. But if you don't know him/her well, AND he made you a meager offer, I'd be suspicious, and would get a second opinion before I wrote it off as fake. Good luck.

    Don't give up on your bracelet just yet! The CT mark WAS used for marking karets in gold jewelry in Europe (especially England until 1977), and there's a VERY good possibility that the CLASP is made of silver with gold plating, or some other stronger metal, since clasps ARE NOT made with 18kt gold--its too weak to hold up over long period of time. I suggest you go to a jeweler who specializes in vintage jewelry, and/or will do a gold test on it. Alternatively, you can also buy your own gold test kit online (Ebay, or wherever). You could also weigh it compared to other jewelry of the same size (crude method, but might give you some satisfaction). All said, I believe your bracelet is actually 18kt gold. The numbering system was also widely used in Europe for marking gold. As far as OTHER gold markings go, it can be mind-boggling, especially ones the French have used over the years. Its pretty much standardized now, but VINTAGE jewelry requires special expertise. Check the website Basic Hallmarks Identification to get just a hint of what you're getting into! Anyway, good luck, and be happy with your find!:)

    On my answer above, the website should read as: Basic Hallmarks Identification

    I guess copy and paste doesn't work too well on this site.

    Okay, it won't let me post the website... :confused: figures. Maybe if you just search out "vintage gold jewelry markings" or "ct used in gold marking" you'll find the site. Good luck! :o
