Charoite Picfest!

                                                 By Ken Casey

Preface    

     Howdy, all!  The last month of northern hemispere summer is here.  Come on along for a
Charoite Picfest
!

     So, tune your eyes to another exotic purple gem, this month's favorite: Charoite!  Let's go!

 

Introduction

     Welcome to our last of 2008's annual Mineral Picfest summer blast! 

     Charoite was found first in Siberian Russia.  If thought of traversing frozen tundra appeals to
you--that's great!  The 'cooler' weather might relieve us from our Delaware summer's heat.  If you
prefer, remain next to your computer for a comfortable look at Charoite!

    Enjoy!

 

A Brief History

    

     Another rare mineral, found only in one gem locale to date is Charoite.  Sources conflict for the
naming of this precious stone.  Some attribute Charoite as having been named for the Chara
River in Russia, near where it was first found in the 1940s.  Others support the Russian root word
for "magic" or "charm" (chara-), which alludes to the mineral's bright coloring.  The name was
officially approved by the IMA in 1978.

     As Syenite intruded into altered limestone, Charoite formed as a gemmy by-product.  Now
exploited as a gemstone, this purple wonder
 

     From a gemstone point of view, an analog to Charoite might be Lapis Lazuli.  Both minerals
have a white mineralization and a golden mineral association that makes them appear sometimes
as a granite or marble.  A Charoite might contain the yellow mineral Tinaksite, comparable to
Lapis' pyrite.  This formation contributes to its complex beauty, thus making for wild, yet classy
swirl patterns suitable for great cabs.

     Check out the photos below to see the emminently bold hues Charoite has to offer!

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 2008-9, we are waiting for your suggestions.  What mineral do you want to know more about?
