According to this article (https://www.researchgate.net/publication/225376850_Compressive_Strength_of_Diamond_From_First-Principles_Calculation https://www.researchgate.net/publication/225376850_Compressi...), the compressive strength of a perfect diamond is, from the weakest direction, -223.1 GPa. The difference in pressure between atmospheric pressure and a vacuum averages 101 kPa at sea level.
Natural diamonds are not perfect, and manufacturing a large perfect diamond is probably very difficult, but I don't think it can be ruled out as impossible.

There's the additional problem of buckling, which has its own dynamics. https://en.m.wikipedia.org/wiki/Vacuum_airship https://en.m.wikipedia.org/wiki/Vacuum_airship
