I am a big fan of rock collecting and would consider myself an amateur geologist. I also like crafts with these materials.

I guess you mean  Amateur geology. It is some hobby which some few people like. You know collecting rocks and mineral specimens from their natural environment.

Yes that's what I mean. I enjoy doing those activities and studying the composition of rocks, of which there are 3 kinds.

Do you do it for money too. Because people that started this did it for commercial purposes.
