    Dust is almost always bad to breathe in. It does not matter if it's
    dust from abalone, pearls, quartz, asbestos, polishing compound or
    whatever. I believe OSHA has regulations about using good tight
    fitting masks to prevent the inhalation of dust. There are a series
    of lung inflammation diseases caused by inhaling anything from
    quartz (silicosis) to lambs wool and feather dust. Protect yourself,
    and wear a mask.
