As I recall (and sorry, I can't find a citation), sodium tetraborate decahydrate (Borax) crystals are efflorescencent, they lose their water of crystallization, and change into a dry powder when exposed to lower humidity.  So you may have a problem with maintaining a decorative crystal.  You could always try varnishing them, it might help.
