Re: WHAT'S REALGAR?
The link to the page for realgar at mindat is http://www.mindat.org/min-3375.html
If I can add to what Lloyd told you. While realgar is poisonous, as long as you don't eat it (not likely) and wash your hands after handling it, it is not to be feared.
If realgar beads or jewelry prompted your inquiry, not to worry. The "realgar" beads are almost never realgar. They are imitation.
