I am carbon 

a diamond in the rough

still dull with jagged edges

I've been through heat

and under lots of pressure

but I still don't shine

people look and stare in my direction

I'm sitting in a room full of carbon

polished and shined to resemble diamonds

but I'll stay in my pure form

until transformation

I wear my jagged edges proud 

and stand out more 

because in a room full of diamonds

I am still pure carbon
