    The beads at that link appear most like glass, although I expect they
    could be some form of quartzite, like what is most often called
    dumortierite. Chemically-stained, well-cemented quartzite will cut
    really nice stones, so we can hope for this to be the case. The
    material is almost definitely not agate, nor crystalline quartz,
    based on the appearance of the beads.
