Here's my new gem oc, Dumortierite! Idk what I was doing with her but I'm soooo proud of her design! I decided I'm shipping her with Graphite, who I don't think I've ever drawn despite her literally being my first Steven universe oc ever, bc they both have like this great Greek goddess kinda vibe, and then I got way to invested in them!
My idea was that dumortierite was a homeworld battle strategist who liked worked with soldiers and sapphires to make like plans of attack for war and conquest or at least that's what she used to do on homeworld before joining the crystal gems to use the same skill. I kinda incorporated both into the outfit I drew her in, with a star and a diamond, but she probably had separate forms.
I'll mention graphite here too, she's a scribe and record keeper on homeworld (you know, cuz graphites a pencil lol)
