Gem form
Hair made of Titanium (Since it's hot the color is yellow like the sun I sent.). At the roots of the hair make it a pink crystal color (reason for pink roots it what happens to sapphire doped titanium)
Skin has splits in it. In between the skin, lays black star sapphire (eclipse colors) this sapphire leads up to the blue sapphire on her face.
Porcelain skin (ref the white block of alabaster and the smoky quartz for more of a skin like color.)
I like the idea that the hair is hot so it can move fluidly
