Hi all,

Here is this weeks edition.
I was poking around on yahoo groups yesterday
and noticed that there are nearly 200 lapidary list.
Many of them have been started in the last year or
two. Many have only a few members. What I do not
understand is why people want to start so many list
thus splitting the Lapidary community into many sub
groups and thus in my opinion diluting any efforts to
gather lapidary information and archive it centrally.
The Orchid Digest is a great example of what can be
accomplished when many persons reside "under one roof".
The Orchid digest has a wealth of information each day
because it has many many members. Please promote our list
on your sites if you have them.

Just to let you know that even though I am on the list I haven't had a
single post to me about the Aussie synthetic material.  You are right that
it sounds like another version of the laser gems material but who knows.

And you still end up with a 'to spec', but flawed, Hubble Telescope from
a math error.

Telescope makers take lapidary to extremes, and measure in fractions of
a wavelength of light.

The skill and experience of the people involved always counts.

Hi, my name is Russell, I have been on the mailing list for a short while,
but haven't as yet introduced myself, not out of dis-interest but out of
lack of time, three small children have been taking most of my free time of

I live in Babinda which is a small town south of Cairns, Australia.  I was
taught to facet at a young age by my father and have recently taken it up again.
I use a "Hall" faceting machine which is locally produced in Cairns.
I enjoy "stirrin' the dirt to find rough to cut, and as the kids get older
intend to get a little more serious.
"Hi" to all and hope to talk more soon.

Dear Criss, A few thoughts tha might help with  polish your jade for the
box. I would urge you to polish the jade before asembling and to try to
stay away fromt he lower grit wheels[100] while fashioning your pieces,
although grinding will take longer on a 180 wheel polishing will go much
faster and better.it seems as if the scratches from low number wheels are
almost impossible to get out and will marr your polish.I find that generall
it in needed to go above fourteen thousand to get a good polish  on jade. I
would stry a  scratch test on the pink areas , I don`t know much about
wyoming material but I once saw a box os samples from that area and several
of the pieces were pink so perhaps the pink material is nephrite. Best
Wishes   kenaii@earthlink.net

Message:07  .............I like the ones with mitered corners much
better than the ones which have the slabs just butted together..........
Have you considered making bezeled corners out of metal such as silver?
Then you could just cut square or rectangular panels. It would look good
and offer corner protection at the same time. Just a thought. Bob

Hi faceters,

More info about the symposium but contact Bob Jimenez for a show packet
and further info.

2004 International Northwest Faceting Symposium in Mt Vernon Washington, USA.
The dates are May 28-30 2004. It will be held at the Cottonwood Inn and
Convention Center in Mt Vernon Washington. It will be hosted by the North
Puget Sound Faceting Guild.

Bob Jimenez will send you an official show packet with more info and designs
and rules for the single stone competition if you contact him

4440 Honeymoon Bay Road
Greenbank WA 98253

Phone - 360-331-4088
email - bob_jimenez@hotmail.com


Bob Long - Bob really shouldn't need an introduction to faceters. He
Wrote the book, in fact he and Norm wrote a whole series of books
on faceting designs as well as the great "Introduction to Meetpoint
Faceting". Long and Steele were true pioneers in faceting design
before tools like GemCad made it so easy.

Dan Clayton - Dan has made quite a few of his designs available on
his website, http://gems-bydesign.com/. He will speak about gem
design with GemCad and testing with raytracing tools.

Ralph Mathewson - Ralph will talk about polishing. He certainly has
the background. Ralph was involved in many IFC competitions and
was a prime mover in the USFG. I think his rules for USFG contests
are about as objective as possible for judging. If you have seen
Ralph's work you know it always has a great polish and the other
workmanship is world class.

Leon Agee - will speak on inclusions in faceting rough and cutting
the Golden American Topaz. We have a number of faceters in the
northwest who cut huge stones, much larger than a "doorknob".
Agee is one of those who have cut monster stones.

Zane Hoffman - Zane's company, Polymetric, makes faceting
machines and the OMF "concave faceting" machine. His father
founded the Prismatic company which still makes faceting
machines under a new owner. Zane is a leader in concave
faceting and will have one or more of his OMF machines doing
a little concave faceting.

John Franke - John runs a business which sells gem rough, cut
gems and other things for faceters. John will share some of
his secrets to selecting gem rough. John will also be a vendor
at the show. His website has a map to the symposium location
at http://gemcutter.com/ John also has a symposium webpage at:

Gerry Klein - Gerry has done quite a few faceting designs and
will speak about optics related to gemstones.

David de Lisle - I don't know David but pictures of his homebuilt
faceting machine on Gearloose's website are intriguing. David
will speak about challenges in faceting machine design and

Demonstrators will include:

Zane Hoffman - Concave faceting
Dan Clayton - Designing with GemCad
Gerry Klein - Optics in gemstones
David de Lisle - Homebuilt faceting machine


Alpha Supply - with faceting machines and many other goodies
for faceters.

Facet Shoppe - John and Barbara will have natural and synthetic
facet rough and other faceting supplies. Check their new supply
of Cristinite. I have not cut this material or even seen it cut yet.
I think it is a borosilicate with a RI about 1.6. It is available in
bi color and trichroic from what I hear.

Drop Ins - These people aren't on the program but I know they
are planning to attend.

Art Kavan - Well know faceter and competitor. Now retired from
competition but he is the president of USFG.

Charlie Moon - Charlie is planning to bring a broad collection of
gemstones cut by Fred Van Sant. Charlie has been a major
force in the USFG but mostly behind the scenes.

Ernie Hawes - Well know faceter, designer and contributor to
Lapidary Journal and the New Mexico Faceters Guild.


Hi Dan, Noticed you in LapBeadary Journal. It is a breath of fresh air
to see something other than beads for a change. LOL

I asked the oldest & best lapidary in our club (his favorite stone is 
jade) which he would do?  polish 1st or after assembling the box.   His
answer: Polish first, do not polish the beveled and/or joining edge(s). 
 Also, how would you polish the inside after box is made?

When he polishes jade he superglues the piece onto a metal bolt, because
of the heat generated.  Normal dopping wax would loosen from this heat.
I have watched him and believe me that bolt gets hot, must be wrapped
with several layers of paper towels.

         If anyone is interested, I've just completed at 12.5mm. 10 carat,
standard round brilliant cut from lithium niobite, one of the exotic
synthetic diamond simulants. This is the clearest stone I have ever cut.
Even the rough looks like clear ice. This material has a super high
refractive index and a super high dispersion. Pictures at

Subject: Smithsonian Genstones Handbook Front Cover Error

From: Kreigh Tomaszewski <Kreigh@Tomaszewski.net>

Over a year ago I picked up a Smithsonian Handbooks volume by Cally Hall
on Gemstones (160 pages, Doring Kindersley Ltd, publisher). It is a
fairly complete survey of minerals that can be cut as gemstones, with
good reference material on measurable physical and optical properties.
It is almost useable as a field guide, but it comes up short on the text
descriptive details, like habit and association information, that you
expect in a field guide. It has great pictures of cut and rough. Its a
decent enough handbook to put next to my field guides, and it gets
pulled down often enough to keep it there.

When I pulled it down today the cover struck me. The top center stone,
pictured between a rubellite and an aquamarine, is a transparent, bright
yellow, cut gem labeled Azurite; if you look on page 83 you can find
what is clearly the same stone pictured as Citrine. And its the 2002
printing (instead of the original 1994, or corrected reprint in 2000).

It is the only error I've found, but it sure is a big one; no wonder it
took me so long to see it, it was obvious.

Lurking is fine, but participation is better for learning !
Post something from your experiences in gemcutting today!

One day, while a blonde was out driving her car, she ran into a truck.

The truck's driver made her pull over into a parking lot and get out of the car.

He took a piece of chalk and drew a circle on the pavement. He told her to
stand in the middle and not leave the circle.

Furious, he went over to her car and slashed the tires.

The blonde started laughing.

This made the man angrier so he smashed her windshield.

This time the blonde laughed even harder.

Livid, the man broke all her windows and keyed her car.

The blonde is now laughing hysterically, so the truck driver asks her what's so funny.

The blonde giggles and replies, "When you weren't looking, I stepped out of
the circle three times!"
