M204 Pyrite Sun

M204 Pyrite Sun


Here’s something we haven’t seen in a while; a very nice Pyrite Sun specimen from Illinois. It measures 4″ x 3 1/4″ x 1/4″ and has not been polished.  Very different and very nice!

Pyrite “suns,” also called “miners’ dollars,” are spectacular disk-shaped mineral concretions of pyrite [iron sulfide (FeS2) arranged in a regular cubic configuration] with minor amounts of marcasite [also iron sulfide (FeS2) but arranged in an orthorhombic configuration, i.e., a rectangular or stretched cube shape]. The mineral disks range from the size of a small penny up to the size of a dinner plate but are commonly about 3 to 4 inches in diameter. Pyrite has a metallic luster and is generally brassy to yellow in color; thus, it is often called “fool’s gold.”
