Here are a few pictures of some amazing specimens of Goethite.
This first specimen is smaller than a dime. Enjoy!

Oh, interesting! I thought you mentioned Crusty's piece wasn't magnetic and that's what threw me off track.

Mike, goethite wont exhibit much natural magnetism (powdered samples may show a little), but heat them up to red hot (dont worry, your samples wont be damaged), and then try it. Youll be very surprised at the difference! -------------------- "Strip mining prevents forest fires..."

Youll be very surprised at the difference! Welcome to the forums Snacksquatch! That is an interesting property of Goethite that I didn't know about. I will try that on a lesser piece when I get the chance. I should make a video about some of these properties. If I can find a way for them to show up on a metal detector then finding them on my claim would be much easier. -------------------- |
