One of our round stone options, Rolling Rock is a river rock that has been worn down by water currents over time. If you ever played in streams as a kid, you may have even given one a toss or two for a big splash. While the majority of Rolling Rock of stones will be variations of tan or gray, there are occasionally some blues and creams mixed in. Most of the surface have been polished by sand and water to a softer look and feel. At least these stones won’t have any bugs hiding under them!
