Perfectly stackable old mine cut diamond seven stone ring totaling around 1 carat in 18k white gold topped in platinum. Substantial enough to wear alone but also layers well with other pieces. Beautiful sparkle factor and bright coloring in the sturdy shank.

Antique box is not included.


Size 7. The largest diamond is about 3.8mm tapering down to 3mm. . I would not remove the stones for an accurate measurement but just using online calculators it is around one full carat total weight in diamonds.

The piece weighs a sturdy 5.2 grams. It stands 3.7mm off the finger. Ring face is 5mm wide north to south.

Please note the measurements as I have small fingers and the pictures can make it difficult to see scale. Antique box is not included.


All my pieces are pre owned and in estate condition. The largest center diamond has shallow flakes of loss on one side. The stone still appears compete and round to the eye but if you look at the surface in a reflection you can see the unpolished area where the flakes of loss occurred. Typical antique diamonds may have some faint natural inclusions but even under magnification nothing is jumping out at me. The vertical edges of the shank may have been detailed / engraved at one point but are smooth now, like they were nested with other pieces. Evidence of a sizing and some cloudy spots to the back of the shank not visible when wearing. The shank is very sturdy. A few worn prongs typical for age but none of the stones move. Still wearable and timeless. But Due to age - please note this is not a mint condition item.

Thanks so much for looking at my shop!

Will be sent with additional insurance, expedited delivery and signature confirmation upon delivery at my cost.

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. 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 described: “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 the individual beauty or sparkle of an antique diamond. Antique diamonds are judged more on the individual character and uniqueness that each one potentially offers.”
