Transparency is opaque. Crystal Habits crystal form is extremely rare, when etched, meteoritic examples may show interesting and complicated intergrowths of cystals according to different nickel-iron concentrates. Terrestrial samples are massive and appear as small flakes and irregular masses. Meteoritic samples are usually rounded, pitted and irregular. Cleavage is absent but crystals will have distinct parallel partings.
Fracture is hackly.
Streak is gray metallic. Associated Minerals are olivine , pyroxenes , and some minerals that are only found in meteorites. In terrestrial samples it is found with gold and platinum and with sulfide ores. Notable Occurrences for meteoritic iron are best found in Antarctica, where meteorites are easy to spot against a background of snow and ice. Best Field Indicators are color, malleability, attraction to magnets and forms.
