Subject: Re: polishing cz
Date: Fri, 25 Jun 2004 20:30:47 EDT
I have not cut cz for years but in the beginning my mentor had me purchase a
ceramic lap since that was the only lap that would easily and quickly polish
cz and beryls and it did and still does. I started cutting sapphires and have
had luck ever since using the ceramic with 50,000 diamond.Not being one to fix
something that isn't broken I have never tried polishing sapphires on my batt
with 50,000 so perhaps that would work also. I read Harv was polishing with
cerium and that I imagine was the problem. I did just recently attempt to cut a
stone for someone in cz and it was a miserable stone to say the least. It cut
quicker than I remember cz cutting and scratched like crazy on polish. I also
had a problem polishing the table because a corner of a 8mm round refused to
polish. It acted exactly like topaz cut on the axis. I finally in disgust
tweeked the angle and polished the corner (looked like crap) and took the darn
thing off the dop and sent it on its way hopefully into the nether world. Has
there been introduced on the market perhaps a new species of cz that may be
manufactured differently from the cz of 10 years ago? That is probably how long it
has been since I cut any and I don't remember it being difficult at all.

Possibly that bad axis was close to a sawed surface? Subsurface damage
from sawing may not show up till the polish stage. CZ is usually supplied
with some cobbed and some sawed surfaces.
14,000 on BATT has been reccommended by lots of people for CZ...but myself,
I never have a problem with 50K on BATT with CZ....going from a GOOD 3K
Many times it is not the polishing step, but a step or two before it that
causes the problem.

I use a 1200 grit on my final cut and then use 100k diamond paste for
polishing on a batt or corian lap. You can use 50k for final polish I
just get better final polish with 100k diamond.

You really need to use diamond on either tin or BATT to polish cz.
Cerium oxide is just too soft to do the job in any reasonable amount
of time. Try your 1/2 micron diamond, some diamond extender, and work
slowly. There is quite a thread on this subject on the USFG list. Good

I've been wondering if anyone has tried one of these new food sealing
machines that produce a vacuum to assist in treating gems with fractures.
Either Opticon or Oiling.
I would think any vacuum will help. Opticon works pretty well if it's
warmed with the stone for a few hours. A light bulb hanging just above will
do the trick as will a toaster oven, you don't want it too hot just warm
enough the opticon turns watery around 120 degrees.
If you go to ebay and search vacuum pumps you will usually find all kinds
of them in just about any price range.
I think a vacuum would be best for rough, thick pieces of whatever. For
slabs and cabs I really don't think you need it.

I purchased a vacum pump from Auto zone for about $30 that is
used to test vacum advance of cars. I plan on using it with a two

In answer to your question. After some experimation I found
ajusting desicators ( vacum cells) to 31-31.5 lbs. per sq. inch. seems
ideal A cheap way I've seen used with mixed results here in Teofilo
Otoni is to put the Optican in a pressure cooker and use a low flame.
Not to precise (pressure not vacum) and sometimes breaks stones but it

Subject: Looking for Good Rough for a Good Cause
Date: Sat, 26 Jun 2004 13:44:14 -0400
From: "Clyde Gilbert" <firstname.lastname@example.org>
I'm looking for some decent facet rough from Africa- primarily pastel
and color-change garnets, sapphire and spinel- for a new art project. If
anyone can help me find good rough at close to "mine-run" prices I'd be
most appreciative. I have contacted several licensed agents in Africa,
but they all sell in kilos and we just can't afford to do that as this
project is to help raise funds for three very worthy causes.
In my perfect world, I'd be able to buy in 10-20 gram lots with stones
ranging from 2-6 cts (larger for the garnets). I'm looking for eye-clean
stones or rough with "interesting" inclusions. These stones are destined
to be faceted and set as eyes in anthropomorphic precious art (sculpted
in exotic wood, stone, meteorite and other materials) designed by
Greenwood Studio, so uniformity in size is a big plus.20
A significant portion of all proceeds from profits (50%) will go in
The Bionic Priestess Project, a 501(c)3 Organization which is raising
funds for Jodi Monogue, a teacher and counselor in the Atlanta, GA area.
Jodi is suffering from liver failure and needs a transplant. Her
condition was diagnosed during a lapse in her insurance coverage and so
she must provide all the money for her transplant. The Bionic Priestess
Project must raise the money to cover the operation as well as provide
for medication for the rest of Jodi's life. Should Jodi not need the
transplant due to a miracle the money will be used to set up a
foundation to help others who need assistance of this type. For those
who wish to donate money to the Bionic Priestess Project, simply follow
The Heifer Project, an International hunger and poverty abatement
program which promotes agricultural, environmental, and economic
sustainability in developing nations worldwide. The Heifer Project has
led the way in fighting hunger, illiteracy and poverty for over sixty
years; this is a fantastic way to direct money where it is most needed
in the "third world". Again, for those who wish to donate money to The
Heifer Project simply follow the link.
The Mythic Imagination Institute, The Parent of Mythic Journeys, a
non-profit educational Conference with a grand mission: The Mythic
Imagination Institute seeks to enliven the human spirit, raise personal
and cultural consciousness, and increase cross-cultural tolerance by
working to promote mythic literacy in our modern world.20
I'll be beginning my purchasing in early August 2004- remember that half
the profits will be donated to non-profit organizations which actually
use the money to help people!
Thanks for the time and space-

I am planning on taking a vacation trip to Brazil and was thinking about going
there when the FIPP gem fair is happening this August so see if I can stop by
the fair to buy some rough. I have never been there. Can you please tell me
if you know what the FIPP show in Teofilo Otoni has to offer for gem cutters?
Subject: More on backup
Date: Fri, 25 Jun 2004 20:53:05 -0500
From: "Paul Newman" <Vet.Surgeon@verizon.net>
I have a great deal of experience with data loss from six veterinary
hospitals that were on a single server. Simple advice to all: backup and
backup often. I am amazed at how few computer vendors ever address this
issue and recommend backup devices or software. Windows XP Home does not
have backup utilities, but Professional does. I suggest simple software like
BackupMyPC or get a Maxtor external drive and it has it's own software.
Backup your entire hard drive about twice a year (more often if you do a lot
of software installations) and then backup only changed files since the last
full backup at least once a week. I have a program that saves files to a
backup every time I save a new file or change one. External hard drives are
the best way to do this. CD's simply do not hold enough information to back
up an entire drive.
Regarding your email, if you use Outlook, you can change your PST file's
location to My Documents and then just backup My Documents often and your
email will be included in your data backups.
Feel free to email directly if you have any questions about backups.....and
lastly....unless you are doing a "verify" of your backup you have not backed
up at all.

Murphy Laws For Frequent Flyers
No flight ever leaves on time unless you are running
late and need the delay to make the flight.
If you are running late for a flight, it will depart from the
farthest gate within the terminal.
If you arrive very early for a flight, it inevitably will be delayed.
Flights never leave from Gate #1 at any terminal in the world.
If you must work on your flight, you will experience turbulence
as soon as you touch pen to paper.
If you are assigned a middle seat, you can determine who has
the seats on the aisle and the window while you are still in the
boarding area. Just look for the two largest passengers.
Only passengers seated in window seats ever have to get
up to go to the lavatory.
The crying baby on board your flight is always seated next to you.
The best-looking woman on your flight is never seated next to you.
The less carry-on luggage space available on an aircraft, the more
carry-on luggage passengers will bring aboard.
