It consists in a floater cluster of two fairly big rhombohedral crystals, of deep royal blue colour, featuring unique polysynthetic lattice mosaic faces with countless tiny parallel faces, making for an extraordinary satin lustre effect. Stunning in person! An unique azurite from Chessy, the only one I have ever seen of that type.
