[Tagging] Surface value for irregular, flat stones with variable gaps

In Brazil there are many streets that have a type of pavement which
I'm beginning to think is rather unique. It is made of natural stones
(granite, basalt, gneiss) cut irregularly but mostly flat on the top,
arranged randomly with random gap spacing, usually 10x15x10cm.  The
gaps are sometimes filled with cement, sometimes not. Examples can be
found by searching Google Images for "pavimentação poliédrica"
(literally "polyhedral paving"). 
Should these be mapped as surface=sett because of the similar average
gap size and similar smoothness, or as surface=cobblestone due to the
irregular cuts and patterns?
