I love theorizing about this show is one problem with that. If the bubbled gem were Pink Diamond (unconfirmed fan name but it fits) it would be diamond shaped (not in the gemstone sense but in the shape sense) as we've seen with the rest of the diamonds so far (Yellow Diamond and Blue Diamond both were like this).

Also (current canon backed theory) Rose Quartz is just Rose Quartz, don't get me wrong, the thought of her being Pink Diamond and changing entirely would be an interesting direction to go with the storyline, but given the current knowledge of the show (and the diamonds) we can only speculate at this time as to who Pink Diamond really is/was.

Last theory, the bubbled gem looks like bismuth (it's a metal I know but it's a bismuth crystal so it kinda fits). Bismuth is seen as a seed, I like to think that this is a backup plan for if the Homeworld's plans were to fall through.
