Icy, raw, earthy and natural... WHAT THE HELL DOES THIS ALL MEAN OR REEFER TOO!!!! Well it 's a catchy name for opaque and some transparent diamonds that have lots of inclusions. There very pretty and some some gorgeous. One does tend to see them in more earthy shade like yellow, terracotta and brown. One can find green, blue,white, grey, black and so on. When there cleaner, more transparent the name icy is very fitting.
