Pyrite
The mineral pyrite, or iron pyrite, forbye kent as fuil's gowd, is an iron sulfide wi the formula FeS2.
This mineral's metallic luster an fauch brass-yellae hue gie it a superficial resemblance tae gowd (that's hou it gets the weel-kent eikname o fuil's gowd). The colour haes led tae the eiknames brass, brazzle, an Brazil an aw, primarily uised tae refer tae pyrite foond in coal.
