Opals have been found on Mars.  Wouldn’t it be awesome to own one?  Talk about the Wow factor.  Instead of saying it’s a Peruvian opal, you could say it’s a Martian opal direct from outer space.  I don’t foresee these being available in the near future, but you never know.

I wonder what the gem lore will be for the Martian opal?  Any ideas?
