A to B
- Acid washed: a process that exposes some of the sand in certain types of stone, giving a rougher texture.
- Aggregate: granular material used in construction. Aggregate may be natural, manufactured or recycled.
- Ahslar: masonry having a face of square or rectangular stones, either smooth or textured.
- Arch: a curved stone structure resting on supports at both extremities used to sustain weight, to bridge or roof open space.
- Belt course: a continuous horizontal course of flat stones placed in line marking a division in the wall plane.
- Border stone: usually a flat stone used as an edging material. A border stone is generally used to retain the field of the terrace of platform.
- Brownstone: sandstone of characteristic brown or reddish-brown colour that is due to a prominent amount of iron oxide, as interstitial material.
- Bull nose: semi-circular, half rounded edge usually applied to thicker slabs of stone.
C to D
- Cobble: usually a smaller format of natural stone used externally as a worn or antique paving stone.
- Cobblestone: a natural rounded stone, large enough for use in paving; commonly used to describe paving blocks, usually granite, generally cut to rectangular shapes.
- Coping: a flat stone used as a cap on freestanding walls.
- Coquina: limestone composed predominantly of unaltered shells or fragments of shells loosely cemented by calcite, very coarse-textured with a high porosity.
- Cornerstone: a stone forming a part of a corner or angle in a wall.
- Curbing: slabs and blocks of stone bordering streets, walks, etc.
E to F
- Face: this refers to the exposed portion of stone. The word "face" can also be used when referring to the edge treatment on various cutting stock materials.
- Finished stone: building stone with one or more mechanically dressed surfaces.
- Flag: a slab like piece of stone usually in larger sizes, most commonly used externally on patios, driveways and paths.
- Flagstone: thin slabs of stone used for flagging or paving walks, driveways, patios, etc.
I to J

- Riven: uneven surface finish usually found on flagstones, exterior paving, and most commonly on slate.
S to T
- Sandblasted (hot-blasted): process where sand is sprayed at very high speed onto the surface of stone, usually to generate a non-slip, or rough finish.
- Slate: a very fine grained metamorphic rock derived from sedimentary rock shale.
- Sound stone: stone which is free of cracks, fissures, or other physical defects.
- Spall: a stone fragment that has split or broken off.
- Subbase: is the first significant structural layer in the construction of a pavement, the thickness of which is determined by the supporting strength of the subgrade.
- Subgrade: the existing ground, or the surface of an excavation, upon which a pavement is built.
- Tarmac: bitumen coating aggregate for driveway or pathway surfaces.
- Terrazzo: a type of concrete in which chips or pieces of stone, usually marble, are mixed with cement and are ground to a flat surface, exposing the chips, which take a high polish.
- Tumbled: a common method of aging stone. Tumbling stone creates an uneven, natural looking rounded edge.
