Besides pyrite, are there any naturally occurring minerals that

Piss

Yellowish varieties of Mica, as a component of sand, can look a lot like tiny flecks of gold

https://en.wikipedia.org/wiki/Brass
some contains Au

Does brass occur naturally?

>>8688284
It's an alloy.

Since people only like gold because it looks pretty, why is Pyrite worthless, and not sold as a poor man's gold?
Is it too brittle to make jewelry out of?

>only like gold because it looks pretty
it looks pretty for a longish time and doesn't breakdown or rust easily

Chalcopyrite

>>8688306
and has the same conductive properties as copper while being more stable in the long run (not rusting or breaking down like you mentioned)

>>8688089
You have to be a retard to think pyrite is gold.

This thread needs a geologist.

Chalcopyrite has been mentioned. Most copper minerals are blue, Chalcopyrite is a rare exception.

Tellurides. Some tellurides contain gold like Krennerite and Calaverite (Sylvanite does too but you might not suspect it was gold) so this might be cheating but copper tellurides do exist and have a gold like color. Tellurides don't actually form bonds, they're more like natural alloys between metals. Anytime copper is in a mineral it has a chance to throw off prospectors.

There are also alloys using gold or copper generated by humans such as Bronze, Brass, Tumbaga and Electrum that can make you think they're gold but by definition human made alloys are not minerals.

Pyrite smells awful

>Most copper minerals are blue
Copper minerals can take on a variety of colors, grey (tenorite), blue (azurite), red (cuprite), green (malachite), and even purple shit (covelite, bornite, etc).

Gold "looking" minerals in terms of luster off the top of my head are:
pyrite
chalchopyrite
pyrrhotite
marcasite
arsenopyrite

If you study more about mineralogy you'll find out that none of these really resemble gold once you look past luster / color. It's generally a big no-no to make an assumption solely based on luster or color.

>why is Pyrite worthless
It's brittle and has a low hardness. I'd imagine that you can't really smelt it easily either due to the sulfur in it. It has striations on it, and it's crystal structure is isometric (think cubes and octahedrons). It's too much of a hassle, when there's already cheaper options for Jewelry. It isn't really all that valuable or precious.

Amateur gold miner here and I got pretty excited when I got into a highly mineralized zone with a pickax and saw all that shiny yellow crap looking like nuggets but yeah, a few seconds dicking around with it...and that is why gold is precious. Hard to imitate, very hard to find and easy to identify. Muh precious.
