It has green sapphires too, to be more precise there are sapphires of various colors. However, the most famous is blue. The only color that does not exist would be red, which instead of being called sapphire is called ruby. But they are of the same variety of stone as corundum, the name only changes because of the red color. (=・ω・=)

umm that be more green than blue. Wouldn't that be an emerald? Not a Sapphire?
