Mind Stone, or the Scepter Gem, is an oval. The tetrahedon is perfect shape for Time Stone, because the ancient Egyptians, and people in modern times all believes that pyramids gathers and holds power to heal and keep things "fresh" if they are in the center, hence why some pharaohs were placed there, to stay as a mummy. Thought Mythbusters busted this, but why not stick with it in the world where demigods, aliens and superheroes are real? :D

Last shape for Soul... maybe a star, or star-like spiked object, thought it doesnt make that much of a sense. Star and Soul? Dont see the connection
