Ten gemstones that are rarer than diamond

I was surfing the web and came across this article on the Ten gemstones that are rarer than diamond. I've heard of Tanzanite and Alexandrite and they did include red diamonds but there are 7 I've never heard of though the only one I'd like to see in person is the Grandidierite which, like alexandrite and tanzanite, is pleochroic, and can transmit blue, green, and white light.
