Space stone

1/6 stones thanos needs to balance the universe. The space at one allows you to travel anywhere in the universe on any planet of your choosing. Thanos wears it on his middle finger knuckle (also where iron man wears it in Avengers:endgame)

Thanos:it's the space stone, or your brothers head
Loki: gets the tesseract
