1.7" Realgar With Quartz & Galena - Peru
This fantastic specimen contains one large red realgar crystal clinging to two massive metallic galena crystals, collected from the Palomo Mine in Perú. Quartz crystals make up what could be considered the matrix of the specimen, with nearly perfect terminations protruding from the quartz base. The realgar crystal is .78" long.
About Realgar
Realgar is an arsenic sulfide mineral with the chemical formula of AsS. Realgar is known for its lustrous red hue, and pristine specimens can be transparent with sharp crystals. The crystal structure is typically stubby and prismatic, though botryoidal and earthy clumps can form as well.
Following prolonged/repeated periods of time under light, realgar will alter to pararealgar. If further left exposed, the pararealgar will crumble to a yellow dust. This mineral instability is particularly troublesome for museums where consistent light exposure has caused specimens to crumble over time. However, short, periodic exposure to light shouldn't alter realgar specimens.
Realgar contains a significant amount of poisonous arsenic, making it somewhat toxic. Therefore, we recommend washing your hands following handling.
