Decorative Rock

Cobble Stone

Cobble stone is merely a larger form of River Rock.  It can be used in the landscape beds and is often utilized in the construction of water ways and water features.  The material itself ranges from just over 3″ on up to 7″.  The cost is higher than that of River rock and the labor to install it is generally higher, as it is harder to handle.
