Blessings everyone! I have been going through my collection of crystals and gemstones, and I am trying to identify them all so I can become familiar with thier amazing properties. As I was sorting, I happened upon quite a few that I am having difficulty identifying. Maybe someone here is able to help. The first one I took several pictures of because it looks both black and deep blue, and very sparkly. The second one i believe may be blue agate? I appreciate any advice!
So very pretty!!! The dark sparkly ones are blue goldstone. I am not sure about the solid blue.

The first one is definitely a blue goldstone as @Artemisia pointed out.
The second one looks like a dark blue agate.
The blue one is blue quartz. And you already know the other one 
The first seem to be goldstone (blue yes) and the other looks like possibly Blue Quartzite?
