Glamorinky Friday IV

For this week’s Glamorinky game you must give a two-part answer:
The name of this stone is __________, and it comes from__________.
This week’s photo has been enlarged to show detail; actual bead size is approx. 28mm.

Players have until Sunday September 10, 2006 at midnight Eastern Standard time to take a guess and put it in the comments section of this post. On Monday September 11, I'll draw or randomize a name and announce it in that day's post. The person selected should contact me through the email link on this blog to give me their address, and I will send them a cool unisex necklace made with this bead!

OFFICIAL RULES
1. You must be 18 or older to participate in Glamorinky Friday. This contest is open to residents of the USA and Canada. Prize values vary. One guess per person per week. You are welcome to post about this contest on other sites, but please do not post the answers anywhere but here.
2. One winner per week will be selected from the pool of correct entries. For weeks with less than 50 particpants, I will be using the ultra-official paper-ball-in-a-hat selection method. For weeks with more than 50 I will use a randomizer. Winner will be awarded prize offered - no cash or prize substitutions. I DO NOT notify Glamorinky winners – you MUST come back to this blog to see if you won.
3. Privacy policy: for now I am not collecting anyone’s info unless they win. I will only use your address to ship your prize, then I can delete it or add it to my database – your choice. I do not share, trade, or sell my mailing list.
4. If you are commenting as "Anonymous", be sure and leave your name with your guess so I can tell who to include in the drawing.
5. I reserve the right to add, alter, or change the rules of this contest. I reserve the right to award a prize of equal value if the advertised prize becomes unavailable.
6. Please send correspondence regarding this contest and all other Glamorsosi business through the email link on this blog.

Now here's a clue: Work hard to find the answer, but don’t blow your top.

See you Monday!
