The Quarry Mill's London real thin stone veneer creates a beautiful fireplace under this large covered patio. London is one of our more popular natural thin stone veneers with its undeniable rustic beauty. The thin stone is cut from natural hand-picked fieldstone. After the fieldstone is collected from centuries-old fence lines, it is squared up with the hydraulic presses. This process of chopping the naturally irregular fieldstone into the more formal squares and rectangles adds another element of visual appeal. London has heavy variations in the colors but primarily consists of a blend of earth tones. This color variation comes from the individual pieces of stone and where they were located within the pile on the fence line.
