e 3210 Finland: I need a list (and pictures) of all available types (and colors) of sandstone and good quality limestone in Egypt. The limestone should be durable so it should be "dolomitic limestone / dolomite" if possible.
What I am seeking:
1) the stone has to be from Egypt (and would also be used there)
2) the stones have to be hard (sandstone or dolomitic limestone), as hard as possible. Granite is not possible. Black "Gabro Aswan" or basalt will be also used in the project, but other stones can not be granites. 
3) there should be three or at least two colours, one grey (or two greys: one dark and one medium) and one light colour, almost white (light beige or light grey or white).
And some questions:
1) Is basalt much cheaper than "black aswan"?
2) Is "black aswan" harder than basalt? (the amount that would be used is enormous...). June 19. Contact
