usually somewhere between 1.0 (loose rubble) and 1.5 (solid stone)

i think 1.25 would be an acceptable guestimate

It would also vary depending on the stone type/density. But I doubt you are talkinh about pumice or marble here so mid range sedimentary stones are going to be similar.

In reality, no stone is going to offer any reasonable insulation so i'd go with either 1.25 or 1.5 and wouldn't expect eitherto have much impact.
