Could-be-Super-Old stacking band, 18K

Well this is an interesting piece! Beside being super charming it could also be super old. The silver set diamond has severe Georgian or early victorian vibes, and the shank, or part of it, can be a relacement. Faded hallmarks to the outer shank. The diamond is chunky and moody and the setting covers a lot of it. Closed back.
For the treasure hunters: I found it totally forgotten and “hidden in a corner” and got it at a great price, and therefore - so do you.

PS: These pieces have lived full lives long before finding their way to you — carrying with them patina, gentle wear, and the kind of character you can’t fake. They’re given only a light cleaning and a quick once-over, so the occasional maker’s mark, hallmark, signature, hidden detail, or bit of history might still be waiting for you to uncover. Price reflects this. Photos and videos are part of the description, so please take a good look and make sure the condition feels right for you.
