It looks like rutile. We have done some TEM observations on rutile in
garnet:

Subject: inclusions in garnet
Dear colleagues,
I found a strange looking ("rhomboidal" location) inclusions in garnet
(Grt-Pl-Bt-Qtz-Sill metamorphic rock from the Ukraine shield). I have no
idea because I've never seen such a thing before. Here I'm sending
3 photos (thinsection, size of Grt is about 2 mm). Please yours
suggestions and ideas.
Regards,
Shauket
