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!

 

Chemistry & Science

     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.

Invitation to Members

Members,

Want to see your name in print?  Want to co-author, contribute, or author a whole Mineral of the Month article?  Well, this the forum for you!

And Members, if you have pictures, or a story you would like to share, please feel free to offer.  We'd like to post them for our mutual enjoyment.   Of course, you get full photo and author credit, and a chance to reach other collectors, hobbyists, and scientists.  We only ask that you check your facts, give credit where it is due, keep it wholesome for our Junior Members watching, and keep on topic regarding rockhounding.

You don't even have to be experienced in making a webpage.  We can work together to publish your story.  A handwritten short story with a Polaroid will do.  If you do fancier, a text document with a digital photo will suit, as well.   Sharing is the groundwork from which we can get your story out there.

Our club's webpages can reach any person surfing the net in the world, and even on the International Space Station, if they have a mind to view our website!

We are hoping for a possible tie-in to other informative programs upon which our fellow members might want to collaborate.  Contact any officer or board member with your suggestions.

Our next MOTM will be a surprise.  For 2007-8, we are waiting for your suggestions.  What mineral do you want to know more about?
