Einsteinit
Einsteinit is not a recognized mineral species in major mineralogical databases. There is no IMA-approved entry or Mindat record by this name, and as such, Einsteinit has not been described with a chemical formula, crystallography, locality, or physical properties in peer-reviewed sources. The term has appeared mainly in informal discussions or speculative contexts rather than in formal mineralogy.
Etymology and naming conventions suggest that, if Einsteinit were formally described, the name would honor Albert
Status and evidence: At present, there is no type specimen, no described locality, and no verifiable data
Notes: Readers may encounter the name in fictional works, educational exercises, or as a potential misspelling
