Why this is evidence: The LK-99 flake slightly levitates for both orientations of the magnetic field, meaning it is not simply a magnetized piece of iron or similar ‘magnetic material’. A simple magnetic flake would be attracted to one polarity of the strong magnet, and repelled by the other. A diamagnet would be repelled under either orientation, since it resists and expels all fields regardless of the polarity.
Caveats There is no way to verify the orientation of the strong magnet in this video, also, there are yet to be published experimental measured values of this sample. Diamagnetism is a property of superconductors but without measured and verified data, this is just suggestive of a result.
Take-away If this synthesis was indeed successful, then this material is easy enough to be made by labs other than the original research team. I would watch carefully for results out of Argonne National Lab, who are reported to be working on their own synthesis of a sample.
This overall corroborates two independent simulation studies that investigated the original Korean authors claim about material and crystal structure, and both studies supported the claims.

Good point, somehow I completely missed the point you were trying to make about getting samples and analyzing them outside of the original laboratory. That would indeed be completely scientific.
Somehow taking the samples out of the original laboratory didn’t cross my mind. What I understood was a team going over there to look at the samples. In that case I would be very weary of any possible manipulations, like with magicians’ tricks or such.
I’m really having issues thinking straight these days with the stress I’ve been under and the stomach flu I just had. Sorry about that brainfart!
