Strictly speaking obsidian is not a rock as it is not composed of crystals so can't be mineralic! It is technically a volcanic glass.
It's Moh's hardness is approximately 5-6 according to the Wikipedia entry for Obsidian although an exact value would depend on the exact composition of the Obsidian in question.
