Steven Universe: Fossil Coral

So, I recently finally watched Steven Universe and I'm now all caught up. -tear- outstanding show.
Thought I'd make a fan character, was going to make a Gemsona but then went...naahh.

So this is Fossil, She's not that well thought out yet, but she's a fused gem of Agate and Coral...have not thought out their designs yet, so for now she's just this lol.
Because of her fusion her left arm turns to sand becoming part of her weapon, a scythe. Whatever her sand touches becomes fossilized. The effects can be reversed when she loses control of her emotions or becomes separated.
She dressed primitive and has a creatures lower jaw in her hair.
Being fused as long as she has, she tends to sleep for long periods of time and always looks tired, who knows how long was her last slumber
