1. FOOLS GOLD PYRITE:
Pyrite is a brass-yellow mineral with a bright metallic luster. The name "pyrite"is after the Greek "pyr" meaning "fire." This name was given because pyrite can be used to create the sparks needed for starting a fire. Pyrite has a nickname that has become famous - "Fool'sGold." The mineral's gold color, metallic luster, and high specific gravity often cause it to be mistaken for gold by inexperienced prospectors. 
2. COLOURFUL HEMATITE:
Hematite is the most important ore of iron. The mineral is used to produce pigments. I was once mined at thousands of locations around the world. Hematite is a reddish iron oxide.
