Hi All,
Thank you to everyone who replied to my questions re Harts Range zircon.
I will play around with my camera using your tips and see if I can
produce some good quality shots.

Hi Cheryl,

> 2. ...photos of the rough what would faceters like to be able to see

Shoot photos of the rough sitting on a white piece of paper
under natural light (a bright but cloudy day works best) with nothing
more than the appropriate color balance for the conditions, using a
decent digital camera.  This gives a reasonable idea of the color of
the finished faceted stones.  A photo or two of cut stones would help
as well.

It was nice to see questions on this subject. I purchased a 10 pound
vibrator on line and was a bit confused on useage. I played around for a few
loads and came up with a few good observations.
I am only using this unit to do the first parts of the tumble process. I
have also added ceramic tumble media to help grind down the rough. I can put
down a load of quartz hardness stones in no time, oh also of course had been
added the silicon carbide. I do wash out the unit but save all the left over
silicon for further projects. Water level is important and you will need to
play with the level, I just watch the tumble and see how the stones are
moving. I do know when I mix in too many pieces that are flat my tumble does
not do well. I have found stones of similar size and shape work out better
and speed the process a bit.
My final stages are done in smaller roller type units . Polishing in the
tumbler did not work well because the unit couild not be cleaned well enough
not to have any left over abrasive from the rough grinds.
I will say that taking down the rough in the vibrator unit is soooo much
faster . My polishing only takes a couple of days after I  beat them up good
in the vibrator.
Thanks again.

Garnet abrasives have a long history in lapidary. Prior to WWII they
were the only uniformly graded abrasive that was available commercially.
If carborundum was used, the user either graded it themselves by
elutriation, or it was only used for rough grinding. Garnet fines were
typically sold graded by the actual grain size in microns; typically
avaliable grades available were 30, 28, 26, 24...,8, 6, 4. They were
made from natural garnets and well graded.

Remember that garnet has a hardness of 6 1/2 -- 7 1/2. If you are doing
quartz or harder you probably need carborundum (or lots of time).
Garnet, like carborundum, will break down over time because it is
brittle. So go ahead and use them in regular grades, if you have them.

If you have only coarse or mixed grit, running it out will probably
work, much like with corborundum (aka, corundum, carbo, "grit"). A
little bit of carbo mixed in sometimes helps speed the process. Don't be
suprised if it takes longer.

Many adhesives are flammable.  I'd find out what kind of "glue" is used on
the lap, especially with a gas oven. Also, it's winter here on the shores of
Lake Michigan and as a result, houses are buttoned down tight.  If you think
solvents smell strong at room temp, they'll positively knock you off your
feet at 200 degrees F.  Think about some ventilation.

One of my good friends passed away and his widow asked me to evaluate  some
aquamarine rough. I do not facet, but I do lots of cabochons so I have
little knowledge of the rough prices. Can any one give me a price range for
some pretty good looking stuff?

From: <wreisbick@mho.net>

This is my first time to post a question, so it is a new experience. I
have approximately a pound of star sapphire rough that looks like so
many rocks but they all have the ability to star. They also change
appearance drasticly when polished. I bought this rough to practice with
but so far I seem to be  missing the mark. Is there an easy method of
locating the correct position to grind the stone?

Great tips !  I was not aware of the delicate balances of water.

I like your idea of possibly transferring to a different tumbler for
polishing. I will try that trick with a different vibrational tumbler /

I have found that slabs need to be separated by up to 80%, non-slab
materials...Lapping together / the sticking together of slabs is a large
problem.. No grinding, sanding or polishing will otherwise occur, unless
slabs are free to receive the carbides and aluminas..

Perhaps I will also increase the power, it's just that the increased noise of
doing so, is a big concern for me in my current living situation..

Thank you

For All National and International Masters, Past-Masters and
World-Class Cutters:

This post is simply a reminder that in 2003 the USFG will host its
first National and International Faceting Competition.  It is called
the North American Faceting  Challenge -- 'NAFC.'   Since the designs
and rules were first published in the 2001 September Issue of  the
USFG's Newsletter, and since they have not been published since 2001,
some of you, who are most capable - skill-wise, may not
know about the competition, and some of you may have forgotten.   The
"NAFC" is an OPEN Competition.   Please note:  The designs and rules
can be downloaded at  <http://www.usfacetersguild.org/events.shtml>.
The closing date is June 20th, 2003;  the amount of time between the
present date and June 20th, 2003 should be enough for all Master
cutters to cut the two required designs -- Fred Van Sant's "Four
Star," and Charles Covill's "Wind Wheel No. 2."   If   further
information is needed, please contact me at <clmoon@pacbell.net>.
