Stone fences have been built since the earliest settlements across the globe. Stone is a widely used material for fences, both for the natural look it gives to the fence, and for its durability over time. Stone fences can be used both to replace classical fences, or as barriers. Stone fences are traditionally created from local stone, with granite and limestone the most common choices. Flagstones are flat stones quarried from mines and then split into pieces. Field stones are rocks found in fields that are byproducts of glacial deposits. They are often round in shape, although their texture and color vary. They can be used whole or sawed to form a veneer. The irregularity of both flagstone and field stone makes for a rustic and custom look. Field stones are free for the taking from your property and fields; flag stones must be purchased. The price for flag stone varies depending on the part of the country you live in and if there are any quarries nearby.
