Trivia: Pyrite, a brass-yellow mineral that resembles gold, is also known as?
Joker’s gold
Gypsum
Fool’s gold
Copper
The correct answer is Fool’s gold
So why is this answer correct? : Named for the Greek word “pyr,” meaning “fire,” gold and pyrite often form together naturally, and in some pyrite deposits, there is enough included gold in the mix to mine for it. Pyrite is often mistaken for gold because the two minerals have a similar gold color, metallic luster, and high specific gravity. There are a few ways to tell these minerals apart, but one of the easiest is a streak test. Real gold leaves a yellow streak and fool’s gold leaves a greenish-black streak.
