Realgar, a colorful arsenic sulfide, is a brittle and unstable mineral which posseses good cleavage. Its inclusion in chalcedony is a rare phenomenon and its fragmentation and scattered placement show that realgar may have developed before the chalcedony. Possible sites of these materials remain unknown.
