My largest five stone to date! Beautiful sparkle to this antique 18k gold ring with a lovely splay of 5 old mine cuts totaling around 1.7 carats. Nice fire to these diamonds! At the moment I am especially drawn to stackable diamond bands and this is a lovely one. I try to acquire as many as I can because they are so versatile and wearable that they are typically sought after.

The setting while still Art Deco era appears later than the diamonds so I wonder if they were reset from an earlier piece? The good news is you get a nice sturdy setting with a quality hand feel and substantial shank! Please do note the dimensions though as I have small fingers and it can be difficult to determine scale from pics.

Antique box not included.

French hallmarks for 18k with goldsmith stamp.


It is a size 6 1/4. It weighs 4.9grams.
The knowledgeable seller I purchased it from estimated it as 1.70cts which my measurements aligned with. I would not remove the stones for exact measurements, but the largest center diamond is about 5.2mm, then two at 4.7mm and two at 3.7mm to give you an idea of scale. They have nice depth to the pavilions as well, especially the center stone.

The ring face is 5.3mm wide (the width of the largest diamond which extends out over the shank) north to the south on the finger with the diamonds tapering slightly in size but all still quite eye catching. And it stands 4.4mm tall off the finger. The five diamonds span about 20mm east to west across the finger.


All my pieces are pre-owned and in estate condition. Typical antique diamonds, they almost all have some natural inclusions - some are linear needle like and some are a warmer light brown silk inclusion including one to the center of the largest stone. A few carbon spots or specks on one of the smaller stones, these things can be slightly eye visible. They also carry up to the surface in some spots where it appears almost like nicks but they are the inclusions that ran to the surface and were polished over. They do not look like abrasions since they are more like a crease shape but under magnification it can look like a hairline until you see that it is within the stone and angling upward. The stones are all stable. But you can see the interruption to the surface if you study it in a reflection very close up and are looking for it. A few small nicks, nibbles, frosty spots around the girdle edges. For some of those I can't tell if it is again the work of an inclusion or if it might be a flake of loss but those parts are seen under a loupe and hidden mostly by the chunky prongs. Just being super picky but with normal wear none of this jumps out. They have a nice bright color and sparkle! Back then they didn't put as much attention on the inclusions so much of this is what we expect to find on antique diamonds. Some wear to the prongs but they are extra chunky so they still have plenty of length left - but something to keep an eye on over years and years.

Shank is sturdy. Still an unbelievable amount of sparkle on this fun stackable piece. It wears beautifully! 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!
