as long as the stone is in a vacuumed jar - there no reason it shouldn't float - that's basically how all steel boats float - having an airtight hull and not exceeding a certain weight - dont know the exact formula, but i know it's somewhere within reason
Supposedly even the ancient egyptians understood this and used huge cargo ships on the nile to transport goods but they dont really talk about this often.
The formula is very simple - the weight of the boat must not exceed the weight of the water it displaces.

They drop two objects in a giant vacuum jar. You'll be shocked to find out that they both still fall. In fact, the heavy object falls at basically the same rate as it does in air. So there goes your theory, empirically demonstrated to be false.
