I think it's fine to just call them Gems for now until we get official confirmation on the true name of their race (Which I'm sure is something other than 'Gems' in their native language)

I guess you could call them 'Gem people' or 'Gems (Humanoids)' if you don't want people to confuse them with actual gemstones.
