While we are talking about these 'containers' for the actual gem inside, a new picture came out with the Collector opening up the Orb to reveal the purple power stone inside. There is also another pic of Ronan weilding this gem within his hammer, which I think greater confirms that the infinity stones can and are being used this way, so I think it's safe to say that Loki's scepter weilds the Mind gem.
