I can relate to the "August peridot" poster---I'm "March Aquamarine" (which I probably would have said), but traditionally it's "Bloodstone". The usual birthstones are (in order): Garnet, Amethyst, Aquamarine, Diamond, Emerald, Pearl, Ruby, Peridot, Sapphire, Opal, Topaz and ... Blue Topaz??? Help me out with December, someone! And, for the record, I believe the t is silent when you pronounce "peridot" (not "dot" (like the contestant said) but "doe")
