Glad you like it! The stone is local (Michigan) river rock. It is a natural stone and is not sold under a brand name although there may be some suppliers that have a proprietary name. We found that it is fairly affordable and available at most stone suppliers in the Michigan area.

Oh well... guess it's not an option for us in Boston - think the delivery might be a bit too much ;) Thank you!

You might find something similar out there but another option could be one of the manufactured stone veneer products.... Eldorado Stone makes a version of this that they call "River Rock". It is not a full dimension stone but looks pretty good. http://www.eldoradostone.com/products/river-rock/

Thank you for the suggestion. I have read good things about their products. Will have to find a location to see the samples in real life to compare to real stone.
