What are the Rarest Gemstones?

you are such a tease

Natural red diamonds are the rarest gemstones on Earth. They are so exceptionally scarce that fewer than 30 pure "Fancy Red" diamonds are known to exist globally, making them highly coveted by investors and far rarer than any other colored diamond, emerald, or ruby.

There is also Kyawthuite only one specimen/gemstone is known to exist! Mostly was talking about the rarest gemstones the average person could aquire.

You look like a gem yourself. Ho ho ho ho
