History and origin
It comes from Brazil, where cinza means grey and andorinha swallow. It is a grey granite widely used in construction for its regularity. It is used for paving, cladding, stairs and worktops. Marmi di Carrara supplies it on request.
Look and veining
The background is medium grey, with white, grey and black crystals evenly distributed. Variation between slabs is limited. Polishing slightly darkens the grey; flaming lightens it.
