The name tourmaline refers to a family of cyclosilicates, that have varied composition, but the same basic crystal structure (FeWO4). There are 11 minerals in this family, including elbaite (the best and most abundant gemstone-quality tourmaline), schorl (the most common variety), and indicolite (blue tourmaline). Tourmaline is extremely common, but most of it is dark, opaque, and ugly. However, the transparent stones are highly valued. The best formed crystals are almost exclusively found in pegmatites, typically elbaite. Tourmaline is known for it’s “watermelon” gems, which are pink on the inside with green surrounding it. It also is the state gem of Maine, due to the high quality gems produced by the Mica Mines. So sorry about the long hiatus, but I recently went to the Smithsonian and they had so many cool rocks, so I’m back! Please, please ask me things!!!

aaaaah here it is!

The cover for Forgotten Adventures!

This is.  Okay, this is probably the most massive thing I’ve ever drawn digitally.  There’s like 70 layers on here.  Maybe more.  It probably took twenty or more hours total to do it, and there were sometimes weeks in between sessions.  I’ve never quite dedicated to a project like that and I’m kind of really proud!

There’s a million and one things I’m still on the fence about but you know what, I’m also pretty happy with it how it is.  Maybe in twenty or thirty hours I’ll look at it and panic and want to immediately redo it, and maybe in a couple months I’ll actually redo it, but for now, this sucker is going up, here and on fanfiction.

also!! shoutout to @a-damn-wizard for letting me have her big sweetie Morganite in an upcoming chapter!  

Enjoy!! (and if you really really enjoy it, commission me! http://chaosflight.tumblr.com/post/159565185629/chaosflight-chaosflight-help-christina-pay-her )
