It seems to be the best evidence! The blue one most resembles Ocean Jasper, and the orange one resembles Biggs Jasper! (not sure if you saw the promo with Bismuth, but she mentioned "Biggs" which also leads as good evidence to this. In addition they did bubble Biggs which means she's in their possession now, so it seems to be leading towards that). I mean it's not exactly stated yet, but they have large Quartz hair too, and their gems are in the same shape as Amethysts (also Quartz)!



I also kind of recall one of the corrupted gems in Attack of the Light (orange light part) where there was a monster that resembled the Jasper we know (helmet and colouring gave it away) and she resembled these beasty corrupted gems that were shown in this episode! (minus the helmet on these ones though). I just can't find a screencap to show for it sadly, I just remember from my own memory ><
