Theme Thursday—complex

There's nothing simple about this large quartz crystal,
just one item in the American Museum of Natural History's
vast collection of gems (3,700 and almost all on display)
and minerals (90,000 and there's no way
they can show you all of those—but what's out there
is pretty amazing, as you can see).

ABC Wednesday—Q is for "quartz"

This amazing chunk of quartz can be seen at—
where else?—the Museum of Natural History.
Almost all of the 3,700 gems in their 
collection are on display, but only 3 percent 
of the 90,000+ minerals.  That's a lot of rocks!
