EXCELLENT post Michael,
I have cut one andalusite 'leaf','S', or San Fransisco Pavilion
(whatever) outline stone, and (quite by accident) it produced a
green in the middle and red on each end! Probably my favorite stone
BTW- I wonder if Thurmond would be interested in either buying
Yourgemologist website or at least starting a third Gemology section
help replace the Forum. I was really enjoying it!

Hi Carl, I visited the Yourgemologist site and the message there
that all the content would be put back up for a while in a few days.
stated that it would be copyright free so I will get a copy of the

Greetings Michael and list...
Great post on the idiosyncrasies of orientation and dichroism ..
with picture links. That pear was really unique! Rarely do I see
this complete so that we can actually learn some of these more "esoteric"
peculiarities of faceting.
My two experiments to date involve a light ametrine with small
change areas side by side deep in the culet of a large "scintillator
brilliant" cut. Face down you could see the colors separately,
up it produced a neat orchid color, a typical example of color mixing.
The other was a piece of 4 Peaks Arizona (or is it 3 peaks?) amethyst
that was of medium saturation, with a very dark colored "spiral"
intense Siberian color which I placed across the girdle and centered
an emerald cut .. that produced my hottest color Siberian stone
You could see strong Siberian flooding thruout the stone but also
magenta spiral that the buyer said added "character" to
the stone. Both
are sold .. these unusual stones go fast and command a premium price.
Great job .. and thanks!
Phil in Florida
Agreed, Michaels Post was most thorough and enjoyable.
Do you have any pictures of your two experiments?

Subject: 45 degree adapters
What works for me is the first step before you place a piece of
rough in the
hand piece is to check your alignment and insure your cheater is
at zero. I
do this with a T bar on a dop. By checking the ends to the lap you
alignment. Second step is to use a 90 degree adapter to cut the
makes one that will fit any 5/8" mast. This takes all the guessing
possible errors with the protractor setting. There is no adjustment
with the 90 deg adapter. If you like to cut the pavilion first so
be it but
cut a temporary table with the 90 deg adapter. I never cut the table
like to be able to adjust the size of the table without cutting
into the star
facets. A small change in the crown mains will sometimes make the
gem in better proportions. Please remember, cutting is an art not

A freind of mine gave me several copys of The Faceters Gem Magazine
the were 1968 thru 1988 copys A lot of the same problems we have
they had in1968 . They addressed polishing problems as well as using
Ceramic laps, In one issue the quote that caught my eye was,"
so many facet diagrams I will not be able to cut them in a lifetime"
we read everyday someone comes up with a "new" facet diagram.
A quote by Carl M. Unruh
There seems to be continuing debate and expectation that a faceting
machine will and should turn out a perfect faceted gem. Don't you
it ! Some faceting skills are necessary.
And this was published in June 1968 some things never change.

Subject: Jubilee Update!

From: Michael Hing <firstname.lastname@example.org>
Sorry about the long gap between updates, but I've been really busy
the run-up to Christmas. I know that several of us are busy cutting
as presents to loved ones, so I expect that the project will start
really pick up speed in the New Year.
Recently, our rough supplier Hilmar very kindly e-mailed his client
to tell them about the Jubilee project. As a result, I have received
lot of enquiries from new members. It looks like about five people
going to go ahead and join us: welcome to the Project!
- One of the Jubilee Project members has managed to organise media
coverage (wow!). Details are enclosed below. Please could you all
contact him directly?
From: Paul T. Ahlstedt [SMTP:email@example.com]
Magazine coverage is confirmed for Lapidary Journal and Rock and
R&G will get a full article which will cronicle the project,
and LJ will
place a short on the project in their "facets" section.
I need you to write all participants and let them knowo that I am
writing the article for this and to take pictures of their individual
being cut, the metal work being done, etc., so that I can tell the
with pictures. I will also need a complete list of all participants
and how to contact
them for release documents, etc.
- To re-cap, here is what you need to do if you are going to cut
for the Jubilee Project:
1) Get in touch with Hilmar Bosch (www.africangemstones.co.za) and
purchase a citrine. You need to let him know that it's for the Jubilee
Project, because he has selected some stones to match for colour.
2) Contact me to get a copy of the cutting instructions. Please
that we're cutting a MODIFIED version of "Classic I" that
is adapted for
quartz, NOT the published version.
3) If you're cutting a pair of stones, then you can go ahead and
your stones (they need to be matched for size!). If you have only
then please contact me and I will put you in touch with a "cutting
buddy" so that you cut a matched pair of stones between the
two of you. I am
one person short at the moment, but hopefully our new members will
4) The deadline has yet to be confirmed but I think the Golden Jubilee
of the Coronation is next summer. We also haven't yet decided how
present the gems, but hopefully I will be able to arrange for people
them straight to the Palace or something.
Finally, to clear up a misconception: at the moment, we're simply
cutting a matched suite of stones: we're not making a necklace at
this stage -
although of course that would be nice! Once we have finished cutting
the stones, then we can decide what to do with them. Several people
suggested that we should try to find a jeweller to put them into
(some of us are also jewellers and might be willing to help out).
at the moment we don't even know how many stones we will get out
project, so it's too early to know what we will be able to do with
However, if you know of anyone who might be interested in joining
who might be willing to consider helping out with the necklace/jewellery
aspect in due course, then why not point them in the direction of
recently-updated Jubilee Project web page (www.maiko.demon.co.uk/jubilee

From: Audrey Gregg <firstname.lastname@example.org>
Does anyone have an extra set of the GIA color tabs they'd be interested
selling to me? If not that, maybe someone knows where I can acquire
Those tabs make it much easier to describe true color when I'm getting
to send out a stone or a parcel. If you'd prefer to contact me off-list,

I've lowered the price on my large lapidary unit to $700 which includes

I have a lap I'm hoping to swap with someone on the list, in exchange
for faceting rough. The lap in question is a Crystalite 260-mesh
WITHOUT CENTER HOLE (ideal for someone who cuts on either a Facetron,
Crystalite "Crystal Master" or any brand of 8" cabbing
equipment with a
1/4"x20 tapped screw holder at arbor's end). I'd received this
for some faceting lessons, last summer, and which has only been
once (literally). This lap is great for speedy stock removal, especially
large, included areas of rough. The reason I'm unloading it is that
neither my Ultra Tec nor Lee faceters, nor my 6" cabbing setup.
make a nice paperweight, though!)
At last check, laps like this listed around $150 and sold around
I'm looking for one or more nice pieces of faceting rough, to total
thereabouts. (Beryls, fancy (orange, pink, green or yellow) Garnets,
Tourmalines and clean Sapphires are my first picks but, if you can
lap, let me know what you have and we'll take it from there.)

For All National and International Masters, Past-Masters and
This post is simply a reminder that in 2003 the USFG will host
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
some of you, who are most capable - skill-wise, may not
know about the competition, and some of you may have forgotten.
"NAFC" is an OPEN Competition. Please note: The designs
can be downloaded at <http://www.usfacetersguild.org/events.shtml>.
The closing date is June 20th, 2003; the amount of time between
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
information is needed, please contact me at <email@example.com>.

First USFG faceting list design competition.
Design: Hexagon or Hexagon Cushion in Colorless or Colored Topaz
Judging: Highest number for total ISO values at 0, 10, 20,30, 40
and 50 degree tilt with five degree head shadow in GemFramx will
win. Example parameters are given below to achieve this configuration.
Online designs must be submitted by January 10, 2003. Design and
cut entries should have the design posted by that date but stone
will take place at the OPLC Hobnob in Tucson in February 2003.
Publication: All entries will be posted on the USFG faceting list
and possibly on the USFG site as well. Designs may be included in
a USFG list CD. Designers maintain copyright to their designs but
must allow posting on the USFG faceting list site. Posting or publishing
elsewhere is not only permitted but encouraged.
Followup: Additional contests may be held for other shapes and
materials if there is sufficient interest and participation.

Values for ISO will be summed and used as ISO total.

points deducted for a missed meetpoint. Fractional
Special recognition will be given to most original design as determined
by team of four judges selected by Jeff Ford or delegate/s.
all work must be done by one individual. In the
case of a fractional indices or an incomplete design a design
coach will explain how the problem can be fixed and the
entry will be moved to Coached class.
more than one individual from a club, guild or area may work together
as a team. If an individual wishes coaching they may do so but most
work must be done by the entrant with only suggestions by coach.

enter as your own. I encourage friends, club/guild members to enter

mentors who are happy to help you.
for a public domain design or a copyrighted design that the copyright
gives you permission to use. You enter design with modified angles,

determined by ISO

Design and Cut,
design will be posted and ISO Total noted but beauty of the finished
will be the judging criteria. Stones will be judged at the OPLC
Tucson. Individual, Team/Coached and Modified designs will be judged
I hope this format will encourage design and optimization oldtimers
newcomers to get involved and hopefully develop their skills. All
entries will be posted on the site and may drive some traffic and
I think ISO Total is as good as any single value to evaluate design
performance but we will look to improve criteria in the future.
