I don't know what type it is. Maybe granite or marble of some sort? It has white sparkles in it.
One test I was told to try with rocks that I wanted to put in my aquarium was to drop vinegar on it to see if it fizzes. If it sits on there for a while with no bubbling, supposedly the rock is not going to add any minerals to your aquarium. Not sure how totally accurate this is, but at least it's a starting place!
