Outdoor pier caps are quarried in several different varieties of limestone, granite and marble and are used both indoors and outdoors in various gardens or public spaces. The term “pin point” refers to the shape of the stone when it is cut rather than polished, as this shape gives it its characteristic aesthetic. These stones do not require polishing to be able to be used as outdoor garden stones. The most common size of pier caps is 24x24x3”, and of course, we make custom sizes as well.
