Finally managed to get this one done... :'D
It's difficult to NOT make her an absolute eyesore...

This is Snowflake Obsidian, the fusion of Obsidian and Cristobalite! ouo

Like Cristo, she's also on her 3rd design, and this one is definitely easier on the eyes than the other two. While Obsidian has more of a physical domination, Cris has the personality domination, meaning Snowflake is tall, strong and relatively silent. She won't rush headfirst into danger, but she will protect others and knows when enough is enough. She's known to fuse to stop fights, especially since Obsidian doesn't quite have enough courage or confidence despite being the physically stronger of the two and Cris isn't the biggest gem and is surprisingly 'weak'. They only fuse when necessary though, so Snowflake Obsidian is a decently rare sight!

The weapon caused me so much issue. 😭 Mostly because I'm a stubborn dumbass and decided to keep Cris' weapon as a projectile, so figuring out how to incorporate a projectile and dual blades was hell. Thankfully my fiance stepped in and helped, so these weapons are loosely based off of StormFlower from RWBY(which I... also don't watch, but I care more about SU).
Thanks to him, we have also come to the conclusion that both Cris and Obsi are part of Little Homeworld, so there's that fun bit of info! :D I'm trusting him with this information.
//Noting: I actually have ANOTHER idea if I were to change Cris' weapon, so I might play with that too... I'm not sure yet...//
