I'm pretty sure that it is a huge chondrule or mega-chondrule. These are not
common, but you can find them from time to time, especially in L6 material.
Have a look at my website, and at the picture on the lower right on the
following page (click the photo to load up a larger image):

This is a nice 10x8mm mega-chondrule in L6 chondrite HaH 173, and it has
virtually the same size as the "object" in your sample.

BTW, if anyone is interested, I still have the sister slice of this one for
trade or sale (with only 7x5mm for the mega-chondrule, though, but with a
neat 5x3mm troilite blob, too). Pictures and specifications on request.

Best,
Norbert
