How are individual pyrite crystals obtained?

0 votes
I recently purchased a nice little, twined pyrite crystal from a mineral show. There is absolutely no sign of any other rock or mineral on it. I am wondering if these kinds of separate crystals form this way, or if they are somehow removed from the host rock?  Thanks

Pyrite forms in many ways. I have found perfect cubes in places, I have found deposits on other rocks

Interesting, have these loose cubes been released after a different mineral has eroded? I am just trying to understand how these crystals can form without being attached to something else. Thanks for the quick answer!
Here is our info/data on pyrite. There are multiple forms.

Iron sulfide is the chemical formula. It forms in several ways under differing conditions. I found it in limestone formations while looking for fossils. I found it on the roadside while walking my dog.
