Peridot can't be Green Diamond firstly because of her gem placement. It's on her forehead whereas the gem placements of the Diamonds in the murals are shown to be on their chests. Regeneration wouldn't affect where the gem is prior to and after regeneration. Memory loss doesn't fit because none of the gems that have regenerated so far have lost their memories. It doesn't fit.

Secondly if she were a Diamond I don't think she'd be taking orders from Jasper because even if she is a lower-class Diamond she'd still be very powerful and in charge.
