Need Help Identifying a Rock

[Bob2677]

Hello everyone.
I found this rock about 8 years ago along Lake Superior in the UP of Michigan. It's been outside on my porch and I picked it up the other day and thought I would try to identify it. It weighs 9.2 oz and measures 3x2.5x1.25in. It feels quite heavy and is slightly magnetic. The pattern on the surface is in relief and the underlying stone is pinkish. My brother in law says he has found other similar specimens but I have never seen one. I googled fossils, meteorites, volcanic rocks, early native american glyphs, martian meteors, nothing comes up. It looks to me like some kind of petrified plant material but its odd how it continuously wraps around the stone. If you can help I would greatly appreciate it. Thanks!

Maybe it's 1200 year old Fabergé's Egg. ??

One of the interesting things about it is that the more you look at it the more it "feels" like there's something decipherable there. It's strange how the pattern changes and has precise structure.

Yes, it really does look like something decipherable. I don't think it is, but it really does look made as opposed to formed.
