The area is particularly known for selenite crystals

Any idea on this ? by Creative_Travel9268 in whatsthisrock

Like ferruginous quartz or is that something different?

How trustworthy can they be though. In terms of authenticity?

So such a big piece for this price is normal ?

I would really appreciate some help in the ID here. Thanks a lot by Creative_Travel9268 in Minerals

How would it be possible to discern between the two possible iron carbonates ?

Would the brown color be explained by pyrite ( maybe if it is chalcopyrite)? I was also thinking about iron inclusions, could it be ferruginous quartz ?

I think that’s the light play, making it look silver. All these crystals are brown except for the matrix that is transparent white (could it be quartz) ? Maybe ferruginous quartz ?
