It looks like the second specimen has brown(ish) inclusions which may be iron. That would kick up the relative density. Also the second specimen has less of an anthracite look to it.

 

Both rocks were found loose, the first in the grass at the top of the formation, the second on the beach at the foot of the formation. I thought it roll down, but they could be different,

When I have them in my hand, they seem to be the same material, but that's is just a guess
