Opal Fluorite 7/23 - 03 - Top Quality, Large, Designer Tear,
Rare Purple, Brecciated
Gem! Here it is. This is the classic brecciated purple type
Tiffany Stone. The kind everyone wants. Unfortunately it's
also very, very rare. This classy, high domed and stunning
gem is not a 100% perfect cab but it is perfectly beautiful.
I have sold many lesser stones for double
my asking price. What else to say? The stone speaks for
itself. Last picture shows the back. AAA+ Collector quality.

Rare Purple Gem of 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
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.
