Physical properties
Tiny blue-gray metallic-looking grain with bright reflective faces; hardness, streak, cleavage, and specific gravity cannot be determined reliably from the image. The apparent size is only a few millimeters.
Formation & geological history
Could be a naturally crystallized sulfide or oxide mineral, a meteorite fragment, or a manufactured metal particle; geological age and formation environment are undetermined.
Uses & applications
Unlikely to have practical use at this size; larger galena, hematite, or magnetite specimens are collected and used respectively for lead ore, iron ore, and mineral specimens.
Geological facts
Color and luster alone are insufficient for identification, especially in a blurry image. A magnet test, streak test, density measurement, and close inspection of crystal form would be informative.
Field identification & locations
Common possibilities include galena (lead-gray, cubic cleavage), magnetite (magnetic, black streak), hematite (red-brown streak), and meteorite metal (strongly magnetic, dense, metallic). Avoid handling unknown lead-bearing material and wash hands afterward.
