OB 3 crown 1 on top of 2 !4 with letter F
by: Anonymous

I have 2 Rose Gold Bands 1 is beautifully engraved with Initials J. H. and a date 6, 6 1908. The ring is beautiful. The other has exact same markings and it has a polished Rose Gold Edge that meets the middle. Rings both test to be below 10K. That is correct with Rose Gold. The engraved one is quite large size 11 and 6mm very wide. The other a 9 and 4mm in width. I have other Ostby Barton Rings and marked OB 14K Maltese Cross. Filigree rings. The beautiful detailed work is magnificent. The pictured information in their OB advertisements tell their Marks. I believe the Letters after the marks are year identifications.. There is a few of their year identifications listed. There must be a list somewhere.

Found Ring from the Past
by: Sarah

While out with my grandmother many years ago (50+!), I found a gold ring stuck in the dirt. I unearthed it and have carried it with me all through my life....wondering about it origins. It is a plain rose gold band with Three simple Crowns on it; one on top & two on the bottom. There is a 14 stamped in a box to the right of the crowns, plus a capital G housed in a diamond shape. Any ideas to its age / origin? Thank you for any information and / or directions.

Crucifix - Gold or not?
by: Anonymous

On my grandmother's jewelry inventory list from 1952, there is an entry for an "amethyst and gold rosary, and a gold case". The reverse of the crucifix has two simple crowns stamped at the top. There are no markings on the "gold" case.

My grandmother's first husband was very wealthy and owned an entire city block in Los Angeles. He was also a jeweler. His brother embezzled from the company and granddad and nana went bankrupt. This could be from the flush days.

3 crown hallmark with e and T rosegold
by: Anonymous

I found a simple rose gold ring when remodeling our 106 year old house. Based on research it appears to be Ostby and Barton with the 3 crown hallmark with a lower case e on one side and upper case T on the other. Wondering when it was made...

Ostby Barton and Three Crowns
by: Anonymous

Hi Flo

Congratulations - it's an Ostby and Barton. Ostby was on BUYING TRIP TO EUROPE and unfortunately boarded the ill-fated Titanic and was one of the passengers on the Titanic who lost their life.

You can also notice the three crowns in their hallmark sequence. See the image in the post underneath.

Best Regards

Ostby & Barton? I think so!
by: Anonymous

I too just received a OB or 08 Three crowns, and what looks like an F or a worn E rose gold ring....I Got it in a mens grab bag, from a goodwill whom filed a notch into the inside, then used acid directly on it. What a shame.. Especially in the case of an Antique Discontinued Marked ring....

I can tell you this much, I do not believe it to be more than a weak 14k, most likely 10-12 or 14k. Holds firm with 10k acid, and weakens a bit with 14k..
Now all of this Ostby and Barton talk everywhere online, had me go and have a look see as to what the markings should look like, and it is spot on with the DISCONTINUED "OB CROWNS A" STYLE...

I do not think this is Swiss in any way, and may be designed after one though. Almost like a "Pseudo Swiss" MARK.

Below is a picture of Ostby and Barton's Hallmarks.

I firmly Believe this to be the work of Ostby and Barton. Swiss markings would be the reverse of the crowns, Two atop one bottom one.

Confirmation!
by: Judy

Hi - I am fairly new to the antique jewelry business and picked up a plain gold band at an auction last night marked with an OB, three crowns with one on top and two on the bottom, and an F. It is also engraved and dated 1908. I was glad to stumble across this discussion, and upon further research found something that I think confirms that the maker of this mark was Ostby and Barton Company. Please see the following link and scroll down a little for the image that includes a short description of the company and pictures of the marks that they used.

Success!
by: Jared the original poster

Wow - Thanks "I have one like this" that link is dead on! I do wonder what the C stands for, they have one in the sketch there that has an "A" and looks exactly the same, otherwise, and it sounds like some other people on this page have a different letter. That's very exciting to know who made it.
From what I"ve heard the letter often refers to a year of manufacture. If anyone comes across the key/legend to those dates, or perhaps other meaning (maybe gold content or something) that's basically the only thing missing. Thank you so much for posting!

Sincerely,
Jared

This has been identified as a rare Ostby & Barton discontinued hallmark. I don't know what the letters stand for, it is difficult to find information about the older hallmarks.

Keeps getting closer
by: Jared

How fascinating! Finnish couple back in the 40s or 50s, Italy in 1933.
I net the fact that the OB and the crowns are the same probably mean a country and the maker. I wonder then if the letter simply refers to the year of manufacture. I've heard that's what they did in England and elsewhere. The letters may refer to the goldness of it too.

My original post I state that the dealer said it was 18K rose gold. Well, I've since learned that that is an impossibility since rose gold is a 9 karat amalgam. Perhaps that's what the C, G and F mean. ALthough, since they are in such close order, I'm inclined again to think maybe they refer to year. It's great seeing new info pop up on here, let me know if anything else pops up!

My Find

Ok this is a great post to find. I also found a gold ring when I was metal detecting with some kind of thin overlay on the out side (greenish) my stamp is...OB, one crown on top of two, 14 F It is a gold ring. Property owner said he remembers an old Finnish couple losing it over 60 years ago.

The ring I have is marked OB, the three crowns with one on top, two on bottom just like the photo and then 14 G. Anymore info on these rings?

Richard Oliver etc
by: Original Poster

Wow, I had no idea this was still active. To answer a question if it is a plain wedding band, YES. It is a plain, rose gold wedding band.

As to the difference in the letter, C vs F, I'd read a while ago that, at least in england, they used a letter to represent the year it was made. It depended on a combination of the letter and the version of the hallmark or something to date the piece. So maybe that's what's going on with our respective rings. A plain letter is so vague that's the only thing I can think of.

Still getting some confusion about the Swedish thing. I'm pretty sure its not the Swedish "Cat's paw" because the crowns are stacked wrong. Sweden has two crowns above a single crown. This has one crown above two. I could definitely be wrong but one poster below seems to have recognized this difference. Not much info on Oliver and Bloomfield, if anyone finds something on them, it would be neat to know more!

Can't wait to see if you all come up with anything. If I find anything else out, I'll let you know!

mystery OB, Letters and three Crowns
by: .AHD P1

We have in our position a ring that looks like the one that is shown as 19th century rose gold ring: OB, C,three crowns.
Our ring has the OB,three crowns and the letter F,
not C.

The ring came from Italy in 1933, on a vacation trip of Europe during that time.

We have asked a museum to do some checking and they came up with this Web page, that shows a ring very much like ours, other than our ring bears the letter F.

It appears the letters "OB" has some thing that deals with the manufacture or the style of ring? The Hallmark the three crowns once again ties to a firm of group that uses this mark to identify their jewelry?

Sweden

Yes it is Swedish. The other mark people are talking about is for silver plated items, hence "silversmiths" in the companies name...

Richard Oliver & Bloomfield Anyone?
by: Anonymous

Could "OB" be the maker's mark? OB are the initials of:

RICHARD OLIVER & BLOOMFIELD (later OLIVER & DAVIS) (Jewelers, New York, NY, USA) - ca 1880s - 1899

The date fits but problem is, I think there may be the double digits 18 (designating the gold purity) between the O & B.

Can you tell us if the ring is a plain rose gold wedding band? Rose gold is made when Copper is alloyed with yellow gold so that a delightful rosy red tint appears in the finished gold. I believe that Rose, red and pink gold are all used to describe this gold color.

Rose gold became fashionable around the turn of the 19ct century which fits. It was particularly popular in Russia at this time.

Nice work, people, Three crowns mark, (on Scandinavian style pieces) IS the mark for THREE CROWN SILVERSMITHS but like the Sweden Country Mark , Two of the Crowns are on the top row and One Crown appears under these in the center. Back to the drawing board...

Three Crown Hallmark
by: Anonymous

I have the same Hallmark with the 3 crowns (1 on top 2 on bottom) on an antique glass bead rosary. Originally I thought it was gold plated, but on closer inspection it looks like very nice gold. Has anyone determined where the Hallmark originated?
