Quasar Diamonds - Tumblr Posts

Regarding quasar diamonds: what are the odds that little crystal Stella pilfed from Umber Tor is one? I'd say they're really small, but then again... I've rewatched that scene several times and the crystal is definitely none of the ones N'than described, and it's got a distinct purple tinge.

so like if quasar diamonds can undo the coin spell. and the relic staff can do the coin spell’s entrapment. then… the purple gem in the relic staff is an outright or corrupted quasar diamond, right?

Is this purple-ish crystal from S4 supposed to be a moon opal??

I'm honestly not sure. Stella seems very... full of purpuse here. And Bait is dismayed

Now look at the moon opal Callum picks up when N'than is explaining about he different crystals:

It's darker, bluer and slightly multi-colored in a way that the gem Stella pilfers just isn't. Stella goes for a crystal that had a purple tinge and no hint of spots where it reflects multicolored light. Is that relevant?? It feels relevant. Maybe it's just a moon opal that will come in handy at some point... But maybe it's not?

Please people help, am I crazy??
