Talk:Lópezite

For certain the first photo listed here (the one held in the hand) is fake (artificial potassium dichromate crystals, not lopezite). The second one is probably not natural either.

It is not a good idea to use the name 'lopezite' for anything other than naturally formed potassium dichromate. Mineral names should only be used to describe minerals, not artificial samples of equivalent chemistry.
