Hi All, 

There were not 10 post so the digest was not produced
since Monday December 1.
Remember the membership decides the Digest frequency
by posting volume. Less than 10 post = NO DIGEST for that
day(s). (Funnies do not count)
Believe it or not it is far easier for me to produce a "Large" digest
than one with only a few post.

Thurmond

Well I'm trying to do another CZ emerald and the only design I can find
I like is a Scissors in quarts. The quarts has an R.I. of 1.54, critical
angles 42/43 and the CZ has 2.2, critical angles 35/41. I have tried to
use the calculating instruction using the scientific calculator and have
come up with several different angles spreads. For the pavilion, the
original angles in sequence are 47.8-43-41-36.3-39.1-31.3 and 52.7. My
calculations run from 68.3-61.4-58.6 and so on to 44.5-40-38.2-33.8 etc.
I think the last set is the correct one but I also came up with
51.3-46-44-38.9 etc. On the crown the original angles are
46-33.5-35-14.7-35.3-28.4 and 42.1. My two sets of calculations start
59-43-45-18.9 etc. and 35.8-26.1-27.2 etc. Again I think the last set is
the correct one. I am trying to use the USFG's "Gemstone Design
Conversion Using Tangent Ratio Method". My questions are, am I getting
close, should I worry that much about it, is it really necessary? Thanks
for any help.
Chuck

Hi Every One,

Hi everyone,

Does anyone on the list have recent contact info (phone number, preferably)
for Jamie Hill of North Carolina Emeralds? Or know someone who might have?

The last telephone number I have, from two years ago, is no longer in service.

Cheers

Today (12/2/2003) the Shop At Home Network was selling rings, pendants,
etc. containing Tropic Fire Topaz faceted stones.  I recall the "Mystic
Topaz" craze of a few years ago, but tropic fire topaz is a new one to
me.  What is it, really?

Hi Tom,  It is probably a thin film mineral or metal coating applied to the stone
via a sputtering or evaporation process. It's thickness is probably measured
in angstroms, possibly microns. Nevertheless it is a very thin coating that
would grind away if the stone was re-cut.

YES it is appropriate to advertise on the list. All that is ask of commercial advertisers
is that they contribute at a ratio of 5 informative post to each ad posted. Commercial
Advertisers are defined by me as those who have a business or web site involved
in the Lapidary Trade or those who seem to never post unless it is an ad.

Lets have a rousing discussion about R.I. and Tangent Ratios. How do you
do yours, is it necessary for all stones, does it really matter a few
degrees one way or the other, and what stones or designs benefit most.
This may hopefully get more posts going and give a lot of information to
fellow Faceters. Unless like me nobody knows how to do it either.

TODAY'S FUNNY ~

From: Doug Smith <gembin@spiff.net>

~ Fair Trade? ~

The Devil tells the young blonde, "Look, I can make you richer, more
famous, and more successful than any blonde alive. In fact, I can make
you the greatest blonde that ever lived."

"Boy, that sounds great!" says the young blonde, "what do I have to do
in return?"

The Devil smiles, "Well, of course you have to give me your soul," he
says, "but you also have to give me the souls of your children, the
souls of your children's children and, as a matter of fact, you have to
give me the souls of all your descendants throughout eternity."

"Wait a minute," the young blonde says cautiously, "I'll bet there's
probably going to be something fishy here! What's the catch?"

TIDBITS AND REFLECTIONS~

Ann Rea's Son **
As some of you may know, one of my sons serves in the military. He is
still stateside, here in California. He called me yesterday to let me know how
warm and welcoming people were to him, and his troops, everywhere he goes.
Telling me
how people shake their hands, and thank them for being willing to serve,
and fight, for not only our own freedoms but so that others may have them
also. But he also told me about an incident in the grocery store he stopped at
yesterday, on his way home from the base.
He said that ahead of several people in front of him stood a woman
dressed in a burkha. He said when she got to the cashier she loudly remarked about
the U.S. flag lapel pin the cashier wore on her smock.
The cashier reached up and touched the pin, and said yes, I always wear it.
The woman in the burkha then asked the cashier when she was going to
stop bombing her countrymen, explaining that she was Iraqi.
A gentleman standing behind my son stepped forward, putting his arm around my
son's shoulders, and nodding towards my son, said in a calm and gentle
voice to the Iraqi woman:
"Lady, hundreds of thousands of men and women like this young man have fought
and died so that you could stand here, in MY country and accuse a check-out
cashier of bombing your Countrymen.
It is my belief that had you been this outspoken in YOUR OWN country we wouldn't
need to be there today. But, hey? if you have now learned how to speak out so
loudly and clearly I'll gladly pay your way back to Iraq so you can
straighten out the mess you are obviously here to avoid."
Everyone in line, and within hearing distance, cheered the older Gentleman,
coming forward as they reached for their wallets.
The woman in the burkha left the store in silence.
I am, like at least some that were in the store, outraged! But it also warmed my
heart to know that we, as American's, are speaking out, calmly and succinctly
(finally) to those that enjoy the freedoms here in the US, but who complain and
berate the very government (and the people) that protect those very freedoms.
Hooray for Rea's son; Hooray for that checker; Hooray for the gentleman in the
store for his actions.
Hooray for Rea for sharing this with all of us.
God Bless America, and Our Troops!
