This is our selection of granite quoins. Quoins are the cornerstones of brick or stone walls. They may be structural, or may be decorative. Architects and builders use quoins to give the impression of strength and firmness to the outline of a building. Rough-finished or rusticated masonry is also frequently used for foundation layers of buildings to give the same impression. Quoinage can be carried out in stone on a stone building, with stone on a predominantly brick building, or by laying brick masonry to give the appearance of blocks at the corner. A split finish means the Quoin has been cropped, leaving a rough, natural finish. A fair picked finish means the Quoin has been sawn to shape and hit lightly with a hammer to give a smooth but uneven finish.
