Type: Ring

Size: 7
Era: Art Deco Early 1900s



Nice and sparkly wide band ring in Platinum with beautiful scrolling engraved details at the shoulders and gallery / vertical edge. This French antique piece has a taller setting that allows the diamonds to shine. Substantial enough to wear alone with around .85 Carat of fiery old cut diamonds. This piece also layers well with flat bands or additional pieces with height, it is fun to stack.

This one is a Paris find. It reads as an ever popular five stone band with the larger old European cuts in graduating sizes across the center. For added sparkle, a pair of single cut diamonds is added by the prongs between each of the larger stones, making the ring face appear completely encrusted and very sparkly.

Antique box not included.

Stamped with the French hallmark for Platinum.


Size 7. Weight is a sturdy 4.6 grams.
The ring face is about 5.5mm north to south and 18mm wide left to right. It stands 4.5mm tall off the finger. The center diamond is about 4.2mm with two at 3.7mm and the end two at 2.4mm. The eight smaller diamonds are 1mm each. Exact depths are unknown as I would never remove them from the antique setting but just using online estimations my millimeter I am getting around .85 carat total weight in diamonds.


All my pieces are pre-owned and in estate condition. Typical antique diamonds with some natural inclusions although nothing dark or really eye visible at all. No nicks or chips. A bit of organic surface wear to the gold but shank still looks great. I love antique diamonds, even those with inclusions or hues typical for the time, because some of those were still among the best available in the market during that period, and were expertly cut by hand to enhance their best characteristics. So I don’t often like to compare antique stones against modern grading standards - BUT these diamonds, for old stones have a particularly lovely fire reflecting a noticeable flash with the other colors of the rainbow. It was actually quite noticeable, especially while trying to photograph it. It also has a bright white color so even though the stones were made long before the 4 C's existed, it sparkles really beautifully. Fun piece to wear and stack as it is so sparkly! But Due to age - please note this is not a mint condition item.

Thanks so much for looking at my items!

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 each stone to enhance it which means that even lower color grades can be cut to appear whiter. (Although it is also worth noting that many antique jewelry collectors prefer and seek out antique diamonds with warmer hues.)
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.” Often there are variations of diamonds in the same piece as the goldsmiths created pieces with the stones they had available to them.
Just an interesting comparison of antique vs. modern diamonds. : )
