>     Is it a pink sapphire if it's clear and a pink ruby if it's opaque? 

    Excellent question! 

    Pink as a colour does not exist. Pink is a de-saturated red. When gem
    is evaluated for colour, GIA used 6 categories of colour intensity (
    how much colour is present ). In order to be called a ruby, the
    colour must be 3 and above. Everything below 3 is a pink sapphire.
    Whether gem is transparent, translucent, or opaque, has not bearing
    on the colour grade.
