How are you doing?
Here I would like to recommend you below Elba Grey Marble which is very popular among designers.
It is widely used as kitchen bench top, kitchen backsplash, tabletop, bar top, TV wall background, wall column, floor tile and so on.
This marble is off white base with grey veins and have some crystal lines, it is elegant and full of sense of design as you can see from pictures.
It is a kind of hard marble which doesn't need any back mesh.
