Zincoln Posted February 28, 2023 Share Posted February 28, 2023 It looks like it could be Jasper? Interestingly, it has well formed crystalline structures which are very bright silver, are magnetic, and don't seem to oxidize. They are single crystal structures dispersed throughout the stone. As a reference, the whole stone is about 1.5" long. I actually found it metal detecting in a wood chip playground and it range up positive. I know it isn't valuable, just a curiosity.

GotAU? Posted March 1, 2023 Share Posted March 1, 2023 Brecciated Jasper? Formed around other fragmented materials and cemented them. That’s pretty cool! 3 Link to comment Share on other sites More sharing options...

Glad you agree I may have been correct on the stone type. As for the mineral, looks pretty neat in situ like it is. Guessing it may simply be pyrite given the cubic form.

Lunk Posted March 1, 2023 Share Posted March 1, 2023 Neat rock. The mineral may be pyrrhotite, a magnetic iron sulfide. 1 Link to comment Share on other sites More sharing options...
Jim in Idaho Posted March 1, 2023 Share Posted March 1, 2023 That is a nifty find, for sure. If I'd found that, it would have made my day. Jim Link to comment Share on other sites More sharing options...
