Working with real stone all day building dry stone walls you'd think we'd know the real thing when we see it. Last night we went out to dinner at a friends house in Sea Ranch and stared at a fireplace discussing whether the stone was fake. We kept looking for clues , concentrating on the pattern, tapping the material, looking at the inside surfaces and studying for phony looking pieces. It was fairly well done work and there was no evidence of any duplicate shaped pieces. In the end I spotted it. Can you see the pair?
