Every face of a granite monument receives a surface finish during fabrication, and the choice of finish significantly affects the monument's appearance, durability, and how lettering and artwork will look on it. Understanding granite finishes is essential for accurate ordering and for explaining the product to clients.
A polished finish is achieved by progressively grinding the granite surface through a series of finer abrasive grits, finishing with a polishing compound that produces a glossy, reflective surface. Polished granite has a mirror-like quality that maximizes the stone's color depth — black granite polished to a high gloss looks dramatically richer than the same stone with any other finish. Most monument faces — the front surface where lettering appears — are specified as polished. Polished surfaces are also the easiest to clean and are the most resistant to staining.
A honed finish is produced by stopping the grinding process before the final polishing step, resulting in a smooth, matte surface with no shine. Honed granite has a softer, more understated appearance. It is popular for certain design aesthetics — particularly for bases or sides of monuments where a reflective surface might look distracting. Honed finishes on monument faces produce less contrast with sandblasted lettering than polished finishes, which is why polished is almost universally preferred for inscription surfaces.
A thermal finish (also called a flamed finish) is produced by rapidly heating the granite surface with a torch and then quenching it with water. The thermal shock pops the surface crystals, creating a rough, non-slip texture. Thermal finishes are used on horizontal surfaces like steps or benches where traction is important. For monuments, a thermal finish is sometimes specified on the base sides to create a visual contrast with the polished top and die surfaces.
A sawn (or saw-cut) finish is simply the raw surface left after sawing a block of granite. It has a slightly rough, uneven texture showing the tool marks from the saw blade. Sawn finishes are used on surfaces that will not be visible — the bottom of a base, for example. In some design contexts, a sawn finish on monument sides can create a rustic or unfinished look that some families find appealing, though it is much less common than polished finishes.
When specifying a monument order to your supplier, you must indicate the finish for each of the six sides of the stone. A standard specification might read "polished front, top, and both ends; sawn back; sawn bottom." Bases often specify "polished top; thermal or sawn sides; sawn bottom." Your supplier will have a shorthand system for this, but confirming the exact specification on every order prevents finishing errors that require the stone to be remade. Getting the finish specification right the first time is a small detail with big consequences.
