Because it's the Mind Stone. Thanos must' have full control of the stone that he was onfident enough to hand it over to Loki. The idea is perhaps that once Loki acquired the Tesserect, Thanos could use the Mind Stone to take over Loki's mind and have him returned it if he prove uncooerative (which most likely seeing Thanos will kill Loki once he's done with him anyway)

As for the color. You're right. It's the same color. It makes everyone think it's just a tesserect weapon. I think it's an error... OR it's not just the shiny stone but the whole cepter. Which means this is the Yellow Infinty Stone reforged into the cepter.
