Awesome French antique Art Deco era cluster ring with a large raised navette shaped face completely encrusted in old cut diamonds. At the center raised in prongs is a larger 5mm old mine cut diamond which perches off the ring face and has a slightly warmer color to it, quite lovely and typical for many antique diamonds as they were often times chosen intentionally during this period.

The other 24 old cut diamonds vary slightly in sizes from 2-3mm, with four smaller old single cuts at the shoulders for added sparkle. It is around 1.5 carat total weight in diamonds. About half the diamonds are the old European cuts with the others being old mine cuts.

Cobblestone encrusted design with a great antique sparkle and I love how the center diamond is raised to allow it to catch the light even more with the pavilion exposed.

I got this in France, it has the French hallmark for 18k gold.

Antique box not included. Please note the measurements as I have small hands and it can be difficult to decipher scale from photos.


The ring is around a size 5 3/4. I couldn't get an exact measurement because it has a sizing bead/ ball rivet in gold soldered to the back inside of the shank. The purpose of these can be for sizing, or arthritic fingers, but also as is the case with this ring – it is to provide weight and a hold at the base of the finger since the piece is top heavy, so it doesn't spin sideways while wearing. It can easily be removed by any jeweler, and especially if the buyer plans to have the piece sized.

The piece weighs a sturdy 5 grams.

Exact carat weight is unknown as I would not remove the stones but the largest measures 4.9x4.5mm and the majority of the others are 2-3mm each. There are four (two on each shoulder) that are smaller measuring 1.2mm each. Using online calculators and estimates I am getting around 1 1/2 carats / 1.5 ctw in diamonds.
Stands 8.2mm off the finger, the ring face is 25x11.5mm.


All my pieces are pre-owned and in estate condition. One of the diamonds at the point has chips with a shallow flake of loss on the underside giving it a frosty appearance. The stones all still appear compete and round to the eye and fill the setting but if you study them with a loupe you can see that and a few nicks and nibbles. This is not visible to my eyes which are in their 40s : ) but may be visible to some if studying it up close very strictly.

Typical antique diamonds with irregular cuts as they were hand cut, they have some very small / faint natural inclusions but none of the inclusions are eye visible and I see no dark or carbon spots. The center has a linear inclusions that carries up to the surface and was polished over, around the outside edge of the table which helps mask it.

The warmer hues are eye visible, the center stone especially reading warmer, with a few others on the warmer side as well, you should be able to detect this in the photos and videos as they are true to life with some taken in sunshine which enhances that warmth, and contrasts slightly with some of the brighter white diamonds. I and many other antique jewelry collectors actually enjoy finding these unique characteristics in pieces from the period. Some worn prongs here and there but all are holding the diamonds securely. Something to keep an eye on over time but all the stones are secure.

Shank is very sturdy. But Due to age - please note this is not a mint condition item.

A note about antique diamonds:
The whole "4 C's" of cut, color, clarity, carat didn't come about until the 1940s so prior to that and especially on antique pieces, there was not as much emphasis placed on those things. (Sure people probably appreciated a certain look of a certain diamond as it appeared to the eye but it was not a graded scale like we have today.)
So it is difficult to judge antique stones against modern day diamonds and their grading system. No two old cuts are the same as they were crafted in times lacking any modern standards. The diamond cutters of the time were experts at hand cutting these stones to enhance them, which means that even lower color grades can be cut to appear whiter. It is also interesting that "lower graded" diamonds in today's scale system, were some of the best on the market during this period!
So it is less about their grades and more about the unique play of light and color that each one can offer. I read one article that put it nicely: “When searching for the perfect old cut diamond (for you), you need to view them through different eyes as you would for a modern diamond, Laboratory grading reports don’t offer too much information in regards to their individual beauty or sparkle which are based more on their individual character and uniqueness that each one potentially offers.” Just an interesting comparison of antique vs. modern diamonds. : )

Thanks so much for looking at my items!
