A market-wide average across qualities and sizes. Your stone's value depends on carat, color, clarity, cut, treatment, and origin.
Realgar is an arsenic sulfide with a vivid orange-red color, very low hardness (1.5-2 Mohs), and perfect cleavage. It degrades to pararealgar powder under light, so faceted stones are fragile curiosities cut purely for rarity collections. It is toxic and must be handled with care.
