Meteorite

Nickel–iron meteorite (likely weathered iron meteorite)

Fe–Ni alloy, chiefly kamacite and taenite

Iron-rich meteorite candidate

Possible stony-iron meteorite or iron-oxide-rich terrestrial rock; exact identification requires testing

Moldavite

Tektite (Natural Silicate Glass)

Tektite (Indochinite)

Tektite (High-silica natural glass)

Likely metallic mineral specimens

Probably native iron or iron oxide/hydroxide material; exact identification requires testing

Magnetite (Fe₃O₄), possibly with hematite and silicate matrix

Likely iron meteorite fragment

Iron–nickel alloy, chiefly kamacite and taenite (Fe-Ni)

Small metallic meteorite fragment (probable stony-iron or iron meteorite)

Unclassified meteoritic material; exact classification requires chemical and petrographic testing

Iron-rich meteorite candidate (weathered ironstone)

Likely oxidized Fe–Ni metal, possibly magnetite/hematite-bearing terrestrial ironstone; exact identification requires testing
