The Facts
•Peacock rock/ore, Chalcopyrite, CuFeS2, named for its colorful iridescent tarnish. This sample is ideal for element collectors on the cheap or those conducting experiments.
•Untarnished peacock rock is a brass yellow color.
•It has a hardness of 3.5 to 4 on the Mohs scale, brittle.
•On exposure to air, chalcopyrite oxidises to a variety of oxides, hydroxides and sulfates.
•Minor amounts of elements such as Ag, Au, Cd, Co, Ni, Pb, Sn, and Zn can be measured (at part per million levels), likely substituting for Cu and Fe. Selenium, Bi, Te, and As may substitute for sulfur in minor amounts
•Chalcopyrite is present in volcanogenic massive sulfide ore deposits and sedimentary exhalative deposits, formed by deposition of copper during hydrothermal circulation.
• Partially magnetic
This is high quality yet cheap affordable Peacock rock
Safety / Caution
•Keep out of reach from children!
•Do not ingest
• It is not known to be toxic but limit exposure.
