ThanksThey look like quartz/chalcedony in pockets growing there. Nice.
Ok, I will look into it. ThanksIt does look like some iron ore (notice the rust spot) with some crystals formed up inside, it will make a nice specimin to put on a shelf. Not sure what type of crystals they are but you can make a guess by counting how many sides the crystal has then look up crystal formations to determine the possible crystals.
