Moonstone or Labradorite

[bunnyfights]

Found in South Central WI.

I believe WI has moonstones. Tagging fernwood for you. I think she had some.

Neither, looks more like a cleavage plane reflection on a weathered Microcline? pebble. Though its possible to find Canadian Peristerite here (glacially deposited) that have a blue schiller and a similar appearance to yours, but I see no color in your video, just a light reflection.

The Wisconsin "Moonstone" is found up in Marathon County exclusively and Labradorite (also a glacial rarity here) would not be that color.

Your video stopped fairly abruptly, maybe there was more to see?

Does not look like WI Moonstone to me. Like fuss said, that is only found in Marathon County.

Could be granite with feldspar.

Testing out my camera's macro feature here.



Rock is hard ~6.5 and feels waxy.

Can anyone help with ID here?

I've found a dozen or so similar pieces on the other corner of Lake Michigan you can see it in the thread I'm linking.  There is an article that talks about the Schiller effect as well.

I'm not sure on the ID of mine either tbh
