Actyally, Gwems don't have a physical form, so they can be anything they want, not just aliens. Also, there is much more about their bodies that we can't understand. For instance, Peridot and Jasper both appear in human form, which mean its normal on their planet, but there must be a reason why. Perhaps, they had much more fluid or not even biological forms on their planet before seeing human bodies, and finding them to be very great. I also have a theory that gems were once mistaken for gods.
