Do you know if it was a real stone versus a cast stone as in concrete? A real stone would need to be sandblasted or acid etched. However a cast stone would be much easier to find or make with a mold.

I'd check on eBay. Then a Google search for cast stone, molded concrete, decorative concrete etc. Good luck.

There's a place around here that does custom rock carvings. They're called "erik's jewelers" in Tonawanda, NY. Strange to have jewelry and rocks together, but they do. Rocks range in size from hand-held to as big as a large TV. Their work is phenomenal. Check your yellow pages for different rock cutters. Call one of the big stone yards and they might know someone who does this.

This may sound a little off-the-wall but given the context perhaps it is not so odd. The people who make headstones for graves would do exactly this type of work in stone. Surely you have a local stonehewer in this line of work, or one not too far away.

These guys are a gardenweb sponsor that do personalized stones

I don't have any experience with them however. Their website looks pretty cool.
