I have about 100 of these rocks found near a artesian well, perhaps native americans used them? They are iron and magnetic.

I seem to remember someone saying that meteorites have no quartz. I never found any quartz in my 100 or so rocks. All of them magnetic.

Now that ruler is deceptive for it says mm but the numbers are in centimeters. The manufacturer should have labeled the ruler as CM, not MM.
