Those bluey coloured areas aren't asbestos are they?

New to me. Really like the right side in first photo. Can’t tell if left side is the skin or not. Thanks.

looks like Pietersite so if it is not solid then it is asbestos. Think of tigereye as fossil asbestos (metaphorically since it was never alive).

Also with asbestos, handle with care and wash hands after you handle it, mask up when you are working with it... Nice material you have there..

Those bluey coloured areas aren't asbestos are they? Unless memory is failing more than usual, not in binghamite. I recall the fibers in binghamite being quartz replacement of parallel needles of iron-rich minerals (such as hematite). In the Minnesota Silkstone (as well as portions of binghamite) the less flashy shimmery areas are replacement of goethite needles that weren't lined up in as parallel formations. As in tigereye, where the asbestine crocidolite-riebeckite fibers are partially or completely replaced by quartz, in binghamite the original hematite, goethite, etc. needles have dissolved and been replaced (though there can be some pits where quartz didn't entirely replace the original minerals). That's quite a colorful piece for binghamite! (ETA: here's a link to the USGS description)

Me too! He's like a walking encyclopedia.
Great look rock, Ali. Looking forward to seeing what you make out of it and how it polishes.

Yep, @rocks2dust nails it - as usual.
That blue Binghamite is a rare find. You should be tickled pink.

I have/had a piece of blue tigereye that was about 2" thick and on one end the asbestos fibers were not completely cemented. You could actually move them back and forth.
