Help ID Agate Like Rock

cjherrington2 · May 19, 2020

I found some interesting rocks just NE of the Cuyuna Range in Minnesota west of Duluth. I was mostly looking for agates but came across some other interesting ones. 1-3 I'm pretty sure are Lake Superior agates, 4 might be binghamite & not sure about the rest. I'm particularly interested in #7. The body is black with yellowish-green spots but closer to the quartz it has much darker red lines. Is it an agate? What else could it be?

They are a little to blurry to get a good look at them, maybe take some better shots outside in sunlight, most likely number 7 is agate or jasper.

Like Steve said, better photos needed to zoom in on.

I appreciate the replies. I also forgot to mention that #7 is magnetic. My phone camera has a tough time focusing on anything closer than about 6 inches away. It's pretty cloudy out today but I'll try to get better shots of it tomorrow. Thanks

Here are a few but I'll try again once I have better sunlight.
I attempted to clean the banded area with a rotary tool so the darker red area I had mentioned is less apparent now.
