About 100 reclaimed granite and marble countertop pieces, different sizes, 1-6sf - $1,100 obo

Details:

These have been used as flooring. We pulled the out and piled them up, so most of them still have some cement sticking on the back. Most of it scrapes off easily. $ 1400 or best offer. Some of the pieces on the picture are already claimed (the black and the blue pieces).
Single pieces are $10/sf.
