'We're going to talk about a compound called 'Fool's Gold', because most people think it looks like gold!'
Nobody else notice the professor subtly call most people 'fools'? :)

The young professor looks so cute !!

I have a rock with fairly large cubes :D
-
Purchased fool's gold from a pirate? I wish my parents told stories like that
-
Also, take a geological "streak" :rub the material in question on a white piece of porcelain. If the color is greyish/brown, it's iron pyrite; If it's a golden color, you have the real thing.

He was such a handsome young man.

@madjimms: Iron sulfide, also known as iron pyrite. Sulfate has oxygen in it.
-
If you take a small sample and smash it with a hammer, pyrite turns into powder while true gold will simply flatten into a thin sheet. Gold is ductile; pyrite is brittle.

@madjimms Same thing, 'pyrite' means 'fire producing' , which refers to the fact that it produces sparks when struck. It's an ancient name, nothing really to do with its chemistry.

Wait? I thought fools gold was Iron Pyrite? not Iron Sulfate......

I had a lovely piece of Fool's Gold once...my mother gave it to me also. However, as any typical sugar-deprived young child is apt to do, I traded it for a cookie at school one day.
