On GH3 textures, I've never found a tool to convert images to the texture format, although it's my understanding that the whole engine is based on one of the Tony Hawk engines (I think THAW). Here's a thread on the Cutting Room Floor forums that discusses GH3 texture ripping. I'm at least pretty sure that the gems are sprites like the other versions of GH3, unlike the 3D models of GH1/2/80s.
