Timur, As you suggested, if a chondrule it might be a very nice type PP (porphyritic pyroxene). Very cool and unique. Wonderful find!

This transparent polished section is now going to America. I think there, if desired, it can be studied.

maybe it is not a chondrule and is a basaltic inclusion ?...unless we have a chondrule type like that...which looks to be made of interlaced crystals.
