The mining of dimension stone is labor intensive, and the cost of the product delivered to an end user is tied to both labor and transportation costs. Rough Stone Rough stone may be subdivided into field stone and rounded river stone. Field stone typically is simply picked up from loose debris material present on hillsides.
In mining: Quarrying and monuments is known as dimension stone. The characteristics required of good dimension stone are uniformity of texture and colour, freedom from flaws, suitability for polishing and carving, and resistance to weathering. This section describes the quarrying of dimension stone. Read More

Dimension stone is natural stone or rock that has been selected and finished (e.g., trimmed, cut, drilled, ground, or other) to specific sizes or shapes. Color, texture and pattern, and surface finish of the stone are also normal requirements. Another important selection criterion is durability: the time measure of the ability of dimension stone to endure and to maintain its essential and distinctive characteristics of strength, resistance to decay, and appearance.

The mining techniques adopted to extract gemstones invariably reflect the nature of the deposit: primary deposits (in hard rocks, worked underground or in open pits) and secondary deposits (found in sedimentary, soft-rock, placers). The mineralogy of a gem dictates the type of geological environment in which it can be found.
Quarrying is similar to open-pit mining except the term is commonly applied to the extraction of dimension stone and aggregates. Fewer benches are required in quarrying than in open-pit metal mining ( Figure 3-4 ); in quarrying, most of the material extracted is marketable.
