Intaglios and Cameo rings. Help dating them!

(Click pictures to enlarge) So I thought I would start my next post here with some cameos and intaglios! The first ring is a white 10k gold cameo. I saved this ring from being scrapped. They thought it was gold filled, paid $5. The cameo is damaged unfortunately. Made be Ostby Barton. The stone is carnelian? Next, I think it was made in the early 1940s but I am unsure on that, help? It's interesting because it looks art deco but seems later... I am stumped on how to tell.

For this ring I am fairly confident this is the 1950s. Sterling 10k top. Who made these rings??

Finally is one of my top rings made by Ostby Barton. Saved from scrapping. I haven't seen one similar. The intaglio in sterling with black enamel? Now it has begun to chip a little bit. Is there anything I can do to protect it? I don't dare get water near it in fear of it getting under in and ruining it further. Again I am thinking 1940s?

Feel free to chime in about anything I really appreciate the expertise here! I should also note most of all my rings are scrap saves. It's amazing what some people are willing to melt down.

 

Last intaglio here. Resembles amber colored glass, but a jeweler actually said it could be a stone of some sort... I forgot exactly what she said. Again no markings here but it is for sure silver. I'd guess early 1900s but I can't narrow it down more than that confidently. Thoughts?

 

Not the jewelry expert. Just my opinions. Someone will be along to correct me.

1.) I think this ring is late 1800s to early 1900s. Carnelian(orange) with possibly
banded agate cameo.



2.) Both appear to be hematite, but difficult to tell from pictures. If the one on the left is a green stone it may be jade. The one on the left is older. I'm assuming the one on the right is the one you think is 1950s. It has a bit of Art Deco design, so it may be 1930s.


3.) This also looks to be carnelian. The flowers look somewhat Art Nouveau. I would put this at the late 1800s - early 1900s.


Again these are only my first reactions to your pictures.
Someone may have other opinions.

 

Thank you! It's hard to tell I know but the sterling 10k top is black intaglio and believe it or not but the silver intaglio is all sterling no stone!! The intaglio is stamped into a solid piece of sterling and there was like this black enamel put inside of it. I'll try to get a better picture of it. But you can see the sterling stamp on the back on the piece.

Also, on that first cameo (the carnelian one) my first thought initially was early 1900s but the Ostby Barton mark doesn't match similar items from the early 1900s....

 

Here is a good picture. Ostby Barton ceased production mid 1950s so it could definitely be late 40s early 50s!

 

Need larger photos and all photos posted at the top.#1 looks like glass or an assembled stone.Look at the photos in this post https://www.antiquers.com/threads/garnet-opal-10k-gold-ring-8k-victorian-ring-time-periods.19188/ ,your photos should show the rings at this size.

 

Oh, you can click on the photos and they blow up to full size and then you can cycle through them. Unless you prefer me to post them full size right in the post but then that would make it very long!

 

Thanks, full image would save us a lot of time, which we could spend on others asking questions. Don't mean to be rude, but many of us don't click on thumbnails if the poster doesn't bother to click on full image.

 

Just thought thumbnails would make for a tidier post but I'll do full size from now on then.

 

I don't mind the size, especially with that many pictures. You don't have to click on all of them if you don't want to. Same as scrolling down the page, and on and on to see all, same effort.
These rings are interesting. The soldier helmet profile motif of the intaglio seemed a very popular one. About 10 years ago, there were lots for sale, which is always a red flag for me, as something recent or brand new. They were of good quality with solid gold settings, so still worth it.

 

A lot of folks are on their smart phones......on a 3 in screen those thumbnails.....may as well be actual ' thumb nails '....
Just sayin........

 

I will post full size from now on! It was just soo many pictures to upload. Also, any more opinions on the rings? Trying to get the thread back on track... Would love to know some more thoughts on the first ring! I agree it looks like the early 1900s but the earlier Ostby Barton marks don't match up to mine which would make me think it is later.... Confusing. Full size images incoming! The second ring I was thinking the 1950s. The third ring is special.... I found one online but all of the black enamel was stripped off. Mine still has some hanging on! Last one must be early 1900s and the intaglio is in amazing condition for the age which is odd, maybe a newer intaglio?

 

At one time there seems to have been quite a fad for men's rings like your first one, many are around. Looks like this one has some damage to the white female figure behind the black hero figure in front? The cameo is agate/hardstone, dyed to get these colors. The figures are not anyone in particular. I don't really know when these were popular, but florid setting strikes me as more 50s than 40s.

Black things are just the devil to photograph. The glare & reflected color on your 2 dark ones make them difficult to assess. First is probably glass rather than black onyx. I can't tell for sure that it is black. Figure is probably Mars/Ares, copied from an ancient gem. Not sure what the setting says about the age. Think newer, not antique.

Love the setting for the third one. Strikes me as having an Art Deco feel. The stone does look like hematite, another popular look in men's ring stones, but, again, pix not giving all the info needed to know. Again, Mars.

The last intaglio is lovely, probably copied from this head of Perseus (after Canova) by Luigi Pichler: http://www.beazley.ox.ac.uk/record/1D2203A2-386C-4DEB-8B74-DEAABE482483
I get a mixed feeling from this one. The setting could be right out of the 60s. But intaglios were not in fashion then. Although it has the look of engraved carnelian, more likely it is a very good quality glass or paste copy. It is unlikely a genuine engraved gem would be set in a cast silver ring, plus the whole art is nearly lost. Taste & fashion left it behind.
