Ho comprato questo braccialetto da un negozio ucraino. Cosa significa questa croce/simbolo?

I’m not Ukrainian (I’m Norwegian), but that pattern is called an eight-pointed star.

It’s an almost universal, traditional design found in ancient embroidery and knitting from Palestine to Norway (and many regions east and west of that).
