8.6" Vibrant Realgar, Pyrite, Galena, and Quartz Associaition - Peru

This incredible specimen features beautiful red realgar crystals, cuboctahedral galena, sphalerite, and sparkling pyrite crystals clinging to an aggregation of quartz, collected from the Palomo Mine in Perú.

Comes with an acrylic/metal display stand.

Realgar is an arsenic sulfide mineral with the chemical formula of AsS. Realgar is known for its lustrous red hue, with the most pristine specimens being transparent with sharp crystals. The crystal structure is typically stubby and prismatic, with botryoidal and earthy clumps known to be possible formations 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 has especially been experienced in museums where consistent light exposure has caused specimens to crumble over time. However, periodic exposure to light shouldn't alter realgar specimens.

Realgar contains a significant amount of poisonous arsenic, making it somewhat toxic. Therefore, washing hands following handling of realgar specimens, is recommended.

Galena is a lead based mineral that is in fact the primary ore of lead, and has been used for its lead content for thousands of years. Galena typically displays a gray metallic luster and forms cubes or octahedral crystals. The chemical composition of galena is PbS.

While galena will not pose a health hazard by sitting on the shelf, or even from casual handling, we suggest washing hands following handling due to the lead content of the mineral.
