Interesting Stone - Having Trouble Identifying

0 votes

Hey, just curious if anyone had clues as to what this stone is? My friend stumbled upon it, and I can't figure out with certainty what it is. Any help is appreciated!

Its definitely been tumbled and polished. Can you take a few more pictures? Also is the black material slightly magnetic? If so it is is probably hematite.

This is not hematite. And Hematite is not magnetic.

Hematite is not strongly magentic, but it is slightly. Its hard to tell from the picture if there is a metallic luster, thats why I asked for more pictures. Another possibility is jasper, if the darker material is just black and not metallic. Hard to tell with just that one picture alone though.

Okay, it's hard to tell from this photograph, but it resembles some of the tumbled material I've seen from the UP in Michigan. That is a combination of basalt and thomsonite, a zeolite mineral. Polished pieces from here are famous in the USA. Again, I agree that we need to see a better photo or two and maybe a hardness test result.
