6 16 universe (the former main universe, which has been bombed) has seven stars, namely strength, soul, spirit, time, space, reality and self, all of which are oval gems.

16 10 universe (the ultimate universe in the past, which has been bombed) is unclear. Anyway, I only know wisdom and rhythm, and I have never seen any pictures. I heard it's oval.

The universe of the Supreme Squadron (I forgot the number, it should be blown up) says that infinite gems are a bunch of boxes.

Apart from movies, Marvel Comics movies and cosmic movies all take place in the universe. According to my personal understanding, the infinite gloves in the movie are not inlaid with infinite gems, but authorized with infinite gems. Otherwise, Thanos can't give Loki an infinite gem to do things on earth. Of course, this guess is not clear, everything is waiting for the movie.

By the way, there is an infinite glove in Raytheon. I wonder what it will be like in the future.
