Judging quality
Genuine slices are strongly magnetic, show a Widmanstätten pattern in the metal after etching, and have olivine in irregular natural shapes. Ask for the meteorite name and classification.
Meteorite
The rarest class of meteorite most people ever see: olivine crystals suspended in a nickel-iron matrix, formed at the boundary between the core and mantle of a shattered planetesimal. Cut into slices, the gem olivine glows amber-green in transmitted light.
