[The Infinity Gauntlet](https://en.wikipedia.org/wiki/The_Infinity_Gauntlet) was designed to hold the six [Infinity Gems](https://en.wikipedia.org/wiki/Infinity_Gems) (or the six soul gems as they are known in some universes). It's sole purpose was to act as a holder to unify the Infinity Gems.

There have been several depictions of the Infinity gauntlet with all the six the gems. Some depict all gems with the same size while the others show five gems with the same size and the sixth gem (at the center) being larger than the others.

So, are all the Infinity Gems of the same size (and what I saw simply was the artist's choice) or are the gems of varying sizes?
