Jasper was, supposedly, the first to cut out the silver on a bracelet, giving it this very distinctive, and handsome, design.
The overlaid silver is filed into the rectangles, and other geometric shapes and polished, to stand out from the darkened (and narrower) cuff.
Result: striking design, excellent workmanship, wonderful bracelet.
Narrow, but very sturdy, it can be stacked, or be the star of your wrist.
In this case, the pictures are worth any amount of words. The overall quality speaks for itself.
