On a visit to Minas Gerais back in June of 2002, I was fortunate enough
to visit the Navegadora (Orozimbo) mine shortly after the excavation of a
huge pocket containing very large crystals of quartz and microcline. The
most amazing was a wonderful microcline accented by balls of cleavelandite
and paired with (yes, the two pieces fit together) an equally remarkable
crystal of quartz. At the time, I was told that the entire lot had been
purchased by someone from Japan. Apparently, that deal fell through because
later that year I was contacted by Lawrence Stoller asking whether our
museum might be interested in buying some large crystals from Brazil. (Yes,
those same crystals!) Needless to say, I jumped at the chance.

Unfortunately, acquiring the crystals turned out to be the easy step.
Finding a way to get a 6-ton (combined) mineral specimen on display has
turned out to be much more complicated. I am happy to report that, 16 years
after their discovery, these crystals are now on public display
(temporarily) at the Los Angeles County Fair. Hopefully, in the future, we
will be able to find a way to put them on permanent display.

I am attaching an image of me with the two pieces taken during setup at
the Fair (giant crystals.jpg), an image of me with the microcline at the
mine in 2002 (microcline.jpg) and an article about the discovery by
Jaroslav Hyrsl that appeared in Mineralien-Welt in 2002.
