Not even a conductor at all, apparently.

https://arxiv.org/abs/2308.06256 this group (mentioned jn the article above) synthesized a fully pure crystal, and found that has a resistance in the several megaohms at room temperature. Just a purple piece of glass, functionally speaking. The thoughts of superconductivity was due to random copper sulfate impurities which DO conduct electricity.
