I would suspect it is essentially invisible to the naked eye. It likely only exists in extremely specific conditions, not just like a sheet. I’m guessing it’s somewhat similar to a microscopic layer around a material that we never notice.

Thin gold layers are green, this looks red if you look at the beaker. There are spectral data available in the original publication https://www.nature.com/articles/s44160-024-00518-4 https://www.nature.com/articles/s44160-024-00518-4

  If I am reading that right, the beaker is filled with lots of sheets and clumps of sheets not just a single one. So, it’s not clear what if anything a single sheet would look like.

  I think gold reflects red light, so it lets greenish light through if you use it as a filter.
