Wood – Should I put grout or something else between hardwood floor and slate stone gap

flooringgrouthardwood-floorstone

This is a new hardwood floor that is next to my slate stone flooring:

The cut was nice and there is about an inch gap in between:

My hardwood floor guy recommended to just leave it like that and not fill with grout.

Is it a good idea to leave it alone like that? And if so, would it get dusty and even broken at the edge over time?

If I fill with grout, would it look ugly? Maybe due to color mismatch with the old grout?

Any other idea or suggestion?

Thanks.

That is not acceptable finished work and the hardwood floor installer should deal with it. There are many options for finishing that kind of transition and leaving a 1” gap with the subfloor exposed is NOT one of them.
