As everyone was so wonderfully helpful the first time, I am back!
This is a rather hefty sterling bracelet my mother purchased at a yard sale in the southern US.
The hallmark is a square box with two lines, maybe a JL or a stylised Z.
The clasp is a magnet with a lock.
Any help would be greatly appreciated... my mom loves this bracelet and would like to find the maker so she can buy more!
