Answer
Hello Earllain,

Having your beads restrung should not diminish its value, but will keep it safe.  You can check with the experts at "Antiques Roadshow" to ask about the value being altered by changing vs. repairing the original clasp, if there is one.

If you want to know what the beads are, you would be best taking it to a local gemologist for identification.
