Shade/texture: generally uniform, but grey tone and speck density can shift between quarry lots—request a control sample for approvals.

Batch control: for one project, book from the same block/lot and keep reference photos/sample on file.

Finish effect: honed/flamed finishes typically read lighter/more matte than polished—confirm finish before final matching.
