It looks like the Pebble Mine won't be paying royalties any time soon... https://www.npr.org/2020/11/25/939010891/army-corps-of-engineers-denies-permit-to-controversial-alaska-gold-mine

It is obviously worth many millions of dollars more than what Hutagalung was paid. It is fraud. An attempt by meteorite dealers to steal the meteorite from Hutagalung. I demand a recount.

It looks carved. The outside rind differs from the inside. Are you sure it is stone? Could it be baked clay? How hard is it?

You learn all kinds of new stuff on these forums don't you! I guess "Omars" all come from a certain formation. But there are lots of rocks that have spherical inclusions that weather out to leave sockets like that. What would you call a rock with a socket in it? Is there a geological name for that socket formed when a spherical inclusion drops out?

You should check the laws in your area. In many locations glaucophane posession is a misdemeanor. Scratch tests are funky. It depends a lot on the texture of the surface and the shape of the tool that is doing the scratching. It is easy to misinterpret the average backyard scratch test. I bet a nickel that stone is serpentine. I would call it serpentine. Especially in a location where glaucophane is illegal.

Morlock, I was going to comment about the olivine.... I have never seen Olivine in a flow like that. Only as crystals. And only in deep volcanics and in the Glorieta Pallasites. It was my assumption that olivine always formed as a crystal under some pretty good pressure. That is just based off my limited experience and nothing else. So im really not sure about that.

Those are spherical inclusions in what appears to be a volcanic or sedimentary metamorphic matrix. There are stones with big spherical inclusions like those in several areas I am familiar with. In those instances the geology is volcanic. But... In my area almost everything is volcanic. From what I understand volcanic rocks are uncommon in your area. I would expect the darker rock to be sedimentary metamorphic rock of some sort with spherical mineral inclusions. I could be completely wrong about it though. I dont know much about rock ID like a lot of these fellows her

All I know about jade is its green. I'm not sure a hardness test or a streak test would help you differentiate jade from other green rocks. If it's not hematite then I really have no idea what it is.

Im calling it a sedimentary metamorphic of some type. It looks like the veins are silica rich and a bit more durable than the rest of the rock. That is why the veins "stand up" a little from the surface. It is mechanically weathered (water/abrasion). That wears more on the softer matrix and the more durable "veins" of silica erode slower. Without a good look at the constituent minerals in the "background " rock it will be tough to classify. For me anyway.

What a great post Slim! One of my all time favorites!

It's hematite.

It is a hematite concretion. A Moqui marble.

Oh come on, can't we play with him for a while?
