|...and each can be part of a solid solution.. Example... We all know Magnetite, yes? But magnetite almost always has a certain percentage of Titanium included not as IMPURITIES, but as part of the regular arrangement of atoms in the crystal lattice... so if you have a chunk of magnetite it is possibly really a chunk of Titanomagnetite, or titanomaghemite, or titanohematite or... something in between. THEN add IMPURITIES and you have the FACT that essentially every mineral sample you can hold has a totally unique chemistry. This piece of magnetite is chemically different from that piece of magnetite.without even considering the odd atoms included as impurities or inclusions. Ascribing healing characteristics to minerals is sketchy enough, but then studying them scientifically shows the potential for nonsense in such ascription. But I digress..." And what about FAKES!??? More on that later...
