I am selling an assortment of vintage to antique jewelry and rings which I have hunted for and gathered from around the world. Some examples seen in the last photo - thanks for stopping by!


Of all the ring requests I receive, the old mine cut cluster is the one in highest demand. And this one is one of my largest with over 30 old mine cuts totaling over 2.85 carats total weight in diamonds. The ring face is Completely encrusted with smaller tiny diamond spacers set in platinum bead prongs to give it an excellent cobblestone texture. High crowns to the chunky diamonds, so fun to view from the side - I'm in love! This one is a real show stopper. I have a similar one in my collection but with warm stones that I am drawn to so I am regretfully letting this whiter one go.

Ornate openwork basket setting to the underside of the domed ring face which is topped in platinum as was customary to set diamonds in a white metal. The rest of this French antique piece is crafted in 18k yellow gold and it is hallmarked for both with a partial goldsmith stamp.

Amazing glitter factor with a large footprint on the finger, around 3/4 of an inch in diameter to the ring face, for that chunky antique sparkle. A real show stopper, it is quite the bauble with exceptional sparkle factor.

Antique box in photos is not included. Please note the measurements as I have small fingers and it can be difficult to determine scale from pictures. Feel free to also request more photos or video as I have many besides those allowed here.


Size 6 3/4. Weight is 8 grams. The ring face is 19mm in diameter and 8mm off the finger.

The center diamond is about 4mm (over .25 carat). The six larger diamonds surrounding the center are 3 to 3.5mm each. There are 17 old mine cuts in the outside halo measuring 2.5 to 2.7mm each. There are 6 diamonds mixed in around the center that measure around 1.7mm each and then additional little rose cuts also added in to completely encrust the ring face amidst the platinum prongs. Varying depths to the stones so exact carat weight is not known as I would never remove them but estimates to at least 2.85 carat total weight in old cut diamonds.


Comfortable to wear for such an attention grabber!

Typical antique diamonds, with some faint light natural inclusions. Many are eye clean and the others are this onlyv very slightly eye visible but seen more with a loupe if you are looking for flaws. A flea bite a nick, a tiny crease from an inclusion leading up to the surface, less than 5 total and again nothing glaring and seen mostly under magnification. The ring has a wonderful chunky sparkle. A very slight warmth to the hand cut stones which is also typical for this period, long before the four C's were created for grading modern machine cut stones. Some of this is due to their chunky cuts giving the piece a great antique sparkle, it is most noticeable in direct sunlight. They have a nice fire along and overall quite bright white color.

Please note that all my pieces are pre-owned and in estate condition. They will have patina, surface wear, a few small nicks. These pieces may also have evidence of a sizing, some build up around the stones and / or inclusions seen under magnification, typical for antique pieces. I have mentioned any noticeable issues above and they are all still wearable and eager to be loved and accepted for many years to come, (the preservation of antique jewelry, even those with signs of their age and history, is important to me. : )
But - Please note due to age, this piece is not in mint condition. Pictures also serve as part of the description and condition report so please utilize the zoom feature which will magnify any wear significantly more than what is visible to the eye while wearing : )

I enjoy making my customers happy and matching unique pieces with new homes. Please feel free to reach out to me with any questions! It means a lot to me that you are visiting my shop! : )

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 for machine cut stones.) 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 collectors prefer and seek out antique diamonds with warmer hues.) Even inclusions were cut around to accent the best characteristics of each stone.

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: “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.”
