“Once in a blue moon”

Is a phrase I’ve heard before

-Each heart’s a Painite

 

*****

In case you didn’t know –

Painite was first discovered by British gemologist Arthur Charles Davy Pain in 1951 and recognized as a new mineral in 1957. For many years only one specimen of the dark red crystal was in existence, housed at the British Museum in London, making it the world’s rarest gemstone.” –MentalFloss.Com
