Stones obtained from quarrying does not contain required shapes and sizes. So, they are cut into required sizes and shapes with suitable surfaces. This process is called dressing of stones.
It is preferable that the stones should be dressed at quarry site which reduces cost of transportation. The weight also gets reduced which is easy for transportation.
Stones contain soft surfaces at fresh stage directly after quarrying, so, dressing can be easily done. Dressing of stones provides good appearance to stones and makes them useful for masonry works.
