A friend of a friend of an acquaintance gave someone I am loosely acquainted with some crystal specimens.

These are from Mt. Erebus in Antarctica, and as I have learned they are fairly rare.

They asked me if I could polish them and wrap them, and if I wanted I could keep 2 of them.

I told them I had no idea how to handle these, but I never let not knowing how to do something stop me from trying to do it, and they sent them to me.

Anyone have any experience with these?

Wow, great catch John. I would really like to see one of them polished but they may be worth a lot more as they are. I would polish one side of one just out of curiosity. Do you have any idea how hard they are. I would start with 220 or higher to see how they grind. You can always go down if you have to.

Hi Jim, the one crystal that is already broken almost has a "mica" quality to it (flake-prone layers). I sense that it is somewhere close to labradorite in how it will work out. It is softer, and I think I will just go *really* slowly with higher grit to carefully work my way into it.
