Have you considered Travertine paver or tiles? These are not man-made products. This is natural stone very suitable for interiors/exteriors. Take a look at our Houzz Page in case you are interested.

Thank you for reaching out. We are always looking for new and exciting materials to incorporate into the spaces we design and build. We will definitely check it out!

We put down this porcelain tile in our foyer last year. It's from Paramount Flooring and made to look like vintage New York brick. Ours is called Central Park Brick.
