this ones dark blue with faint light lines going through it
This one looks like Lapis Lazuli. There's an outside chance of it being Sodalite, which is a similar shade of blue, but most Sodalite I've seen has a bit more white mixed in. Lapis Lazuli is more likely to be more consistently blue throughout the stone, like this.
If you notice silvery flecks of Hematite occurring in this stone, that would make me lean even MORE toward saying it's Lapis Lazuli.
