[meteorite-list] Interesting crystal in meteorite - what is it?

[Greg Stanley]

Gary:

That is an amazing specimen.  My first thought would be a plagioclase, but I noticed in the video that at one angle it looked greenish; perhaps some kind of orthopyroxene that is exhibiting iridescence.

Please let us know when you get the test results.
