Base Green - Peridot
Base Blue - Blue Diamond
Base Red - Garnet
I think I'll either go with Pearl, Sugilite, Rose Quartz, or Amethyst for the next one. I started a picture of Lapis, but I decided against finishing it for a number of reasons. It's currently with Jaxx Amberstone, and she's welcome to keep it if she wants.
Lapis Lazuli broke the adorable space triangle too, so uh. Yeeeeeeh.
