SAM2 WROTE:”
Nitpicker: I believe there is a T’shuvas Harosh that says that the black stone is Assur to put in a shul, but not Avodah Zarah. And the Ran clearly disagrees with your statement (R’ Ovadia’s explanation cited above notwithstanding).

Please explain. I don’t understand this at all. I thought there was only one black stone, a relic found in mecca. you cannot put that one in a shule, it is not available.
also, which statement of mine does the ran clearly disagree with? I was not sure what you meant.
