Edging or setts to go with black limestone

[r4vvm]

I am having black limestone paving fitted for a patio area.

Was thinking that it may be a little dark having black limestone everywhere so want some edging but not sure what will look good.

Have seen sawn granite setts which look nice but thought id ask you guys as you probably would have done something like this already.

Also interesed in tips laying the patio and how to keep that dark look. I know that i probably cannot seal till 6 months time?

Black limestone will not be black in 3 months' time! - https://www.pavingexpert.com/stonpv05

And generally speaking, any sawn granite (more or less) will look good against the limestone, whether it's greyed or not!
