Re: Re: ND Rock

I don't think it is basalt with feldspar, if so, the inclusions should all be quite angular, as the feldspar crystals form within the molten basalt. For the most part, the inculsions in this piece appear to be quite rounded. Would help to know how hard it is, Francine. Can you scratch it with a knife, or does it scratch the knife? Will it scratch glass? That would let us make a more educated guess.
