Hi I am looking for crystals I can use in the world of my novel but I have no idea what types to use or what there are.
So my question is what kind of crystals fit these criteria:
- They must be able to exist “permanently” without breaking down in normal earth conditions/atmosphere.
- They must be able to grow quite large. (I’m thinking about large hexagonal crystal columns)
I would be very happy if you could list any crystals you know that fist the criteria. With the name I should be able to research further myself and narrow it down. Thanks in advance.
P.s. some of you might have some feeling of déjà vu reading my question as I asked a similar question before but that one was marked as to brought so I am asking it again but trimmed down. link: How do i create a significantly correct world with large crystal formations in my novel?
P.p.s. if this question is to brought as well please leave a comment explaining how I can make it better because I otherwise really have no idea how to fix it.
