Whether or not it's the world's rarest mineral, reidite, a mineral that is formed during powerful asteroid/meteor impact events, has only been found in six places on Earth.
Western Australia is the sixth.
Ultra-rare mineral that only forms when meteorites slam into Earth discovered for only the sixth time
Would you like to know more about reidite? So would I.
Reidite Mineral Data
From this I discover, with no prior knowledge, that one of the places it has been found is the Chesapeake Bay impact structure, located not far from where I live.
Here's a picture of reidite. It's the white streaks in the enlargement. The background is a human hair - reidite gets formed under the high pressure of an impact from zircons already present in the rock.

Benitoite
Benitoite, only found at one location in California. The location has been all mined out.
One interesting crystal structure it occurs in is a truncated pyramid.
Some of the more expensive specimens are the "sushi plates".
Even though it was found only at one mine in California, and it's all been mined out, it is still widely available and not too expensive. Benitoite gems are placed into many different jewelry designs.
Thanks for the info!
