Granite is a coarse-grained intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma that slowly cools and solidifies underground.

It is a common stone, available in many colors.

Granite is massive (lacking internal layers), hard, and tough. These properties have made granite a widespread construction stone throughout human history, and bring specific characteristics.

Smaller stones are usually split all sides, showing a characteristic rough edge and surface.

Bigger pieces are instead obtained by sawing the blocks to a specific thickness. The resulting surface is not suitable as is, and need to be further processed, with thermal finishing, or bushammering.


Granite is found in blocks, so big sizes can be produced. It is suitable to cut-to size fabrication, and the most common shapes/surfaces are:

  • Cobblestones 4”x4”: The traditional granite cobblestones have all 6 sides split; the more refined ones have the 4 edges sawn with the top face flamed. Other combinations are possible, like edges split and top flamed.
  • Tiles: several sizes are available, from 6” to 36” in width and length.
  • Surfaces and edges: Tile usually have flamed or brushed surfaces, and the edges are mostly disk cut

Monolithic pieces: considering the size of blocks, pieces up to 4’x8’ can be produced.
