Its kind of heavy for it size, though not extreme - about two pounds. Looks like a chunk of metal, but not quite sure what it is.

  • $\begingroup$ I have seen various ferro-ores that look like that ( eg. ferro-vanadium , used as an addition to molten steel to make alloy steel.) $\endgroup$ – blacksmith37 Mar 20 '18 at 19:37
  • $\begingroup$ Location is really important in the identification of minerals. There are several tests you can do to determine what it isn't. An easy test is to simply run a strong magnet over the entire surface of the sample, and determine if it contains iron or not. You can also do a streak test; this is done by rubbing the sample on a piece of rough marble or unglazed ceramic, such as the back of a ceramic floor tile, then observe what color it leaves on it to narrow it down. Also try using the hardness test. I hope this helps! $\endgroup$ – Armondo Villaescuza Mar 22 '18 at 8:43
