Preface
Now,
it's July, and time to continue our annual Summer Picfest with Rubellite. With
it's pink-red color, Rubellite is prized in both red and "bubble gum pink"
colors. So, get
ready for some more mineral eye candy with this month's favorite: Rubellite! Let's
go!
Introduction
Welcome to
another annual Mineral
Picfest!
Rubellite is our
esteemed choice this month. Essentially, it is Elbaite with a color
ranging from pink to red, and without the green typical of Elbaite. Please have fun
browsing
our virtual Rubellite museum this month, and visit a link or two.
Enjoy!
Rubellite's name derives from the color red.
Striking examples of both mineral specimen
and faceted gem both delight and wow the connoisseur. With it's characteristic color
spectrum,
Rubellite may be distinguished from either garnet, ruby, and spinel by eye.
Rubellite is part of the Elbaite Group. Elbaite forms in three different series,
the: Elbaite-
Dravite Series, Elbaite- Series, and Elbaite-Schorl Series. All of these are part of
the
Tourmaline Group.
It's chemistry is that of Rubellite with it's chemical formula: Na(Li,Al)3Al6(BO3)3Si6O18(OH)4.
Note that Rubellite is both Lithium-rich and Iron- and Magnesium-poor.
Also found in pegmatites and gem pockets, the red variety seems to be more prized than
the green these days. Of course, it's up to you, which you prefer. I like
both!
There are about a handful of superior gem-quality known localities worldwide, according to
the mindat.org database. Of the
eleven prime locales, three are in the western United States,
three in western Europe, and three are widely dispersed across Asia. Two of my
favorite are
western Maine and Minas Gerais, Brazil.

Uses
Tourmaline has had two
major uses: as a piezoelectric plate in instrumentation and as
a supreme gemstone. Some of the gemmiest Rubellite comes from Maine, Brazil,
Afghanistan,
Pakistan, and Nigeria.
