Dear Allan:
“
How do I determine the grade of travertine or other stone?
”
You don't. It takes a true expert to determine that.
As a rule of thumb, going by my limited direct experience, the Big Box stores carry the lowest grading possible.
One more evidence that the world needs marblecleaning.org!
