Below is an Umba Sapphire Parcel(natural, unheated). This is fairly typical of what is available, that is if you wallet is deep enough.

Are all Sapphires blue? Absolutely not, Sapphires come in almost any color, including bi-color stones, color change stones and and white (clear). White Sapphires are often used as accent stones in jewelry in place of diamonds.
