Sure enough. Which, well, makes sense, since superconductors are "perfect" diamagnets, so them being able to do it seems to necessitate that the greater class of diamagnets on the whole can too.

The only examples I can find of stable non-superconductor diamagnets involved 4+ magnet arrays, though, or multipole magnets, e.g. https://phys.org/news/2014-08-diamagnetic-levitation-pyrolit... and not dipole configurations like this video seems to show.
