Opal Fluorite rough 9/25/11
- 07 -
From my cutting stash... 4 SUPER Nice - HIGH GRADE
FACED / PROVEN CHUNKS and one extra piece for good measure.
These are exceptional pieces and will each has something
different going for it - lots of good cutting here. These
are the cores of some of the best stuff I've been cutting
lately. That cube shaped one is 3.5 x 3.5 x 4 inches -
enough for an over the top quality sphere, or cab it up for
some very valuable gems. You
don't see a lot of Tiffany stone this nice these days.

Rare Rough Opalized Fluorite!
This material is one of the most scarce,
beautiful and unusual stones in the world, this stone only comes from
one very small area of beryllium mines in the Utah west desert where
they mine (the 4th lightest element) beryllium for use in missile nose
cones and many other high-tech metallurgical uses. It is not open to
the public for collecting and very little of this material sees
anything other than the ore crusher to extract the about 1% to 2%
beryllium contained in the opal tuff. Try to find this exquisite
gemstone and you'll see that it's not only very rare, it is
very scarce. It is a soft to hard opalized stone that forms in
very small to 100+ pound "nodules", composed of predominantly
opalized fluorite (blues, purples and whites), often with many
other minerals such as quartz, dolomite, rhodonite, manganese,
beryllium and other surprises. It often has a "crackled" appearance
and is sometimes called "Tiffany Stone", "Bertrandite" "Purple Opal"
or "Ice Cream Opalite". I call it Opal-Fluorite. This material has become
scarce. Get it while you can.
