I’ve found quite a large druzy quartz or chalcedony mineral formation with what looks like 3-D tube structures throughout. It’s very sparkly with clear to green coloration and the pieces range anywhere from 1 lb to 30 lbs. They were exposed during demolition while constructing a housing development, inside a very large boulder in Kalama, Washington. Has anyone ever seen something like it? I’d really like to know what it is and what it’s worth?

Yes, looks like chalcedony - and such formations as this are not too uncommon. No one will nor can give you a price, as this is a non-commercial site. Check the hardness and perhaps the specific gravity of a small piece to make sure as to what it is.
