On reply about turquoise, to John McLaughlin and all-
Sorry to hear about that experience with Bad Boys of Cripple
turquoise. I am glad that I worded the letter carefully and said
I had no
experience with them, but perhaps someone else did. I was surprised
(see the below cut and pastes from correspondence).
"At present we have a nice selection of both blue and green
The price of the rough depends on the size, starting with $100
per pound for
chips up to $800 per pound for specimens. Most craftsmen want
$250-300/pound size which is about 1-1/2 to 2" in size. We
do not have a
minimum order and we do accept Visa, Mastercard and American Express."
"You certainly may order 1/2 lb of blue, but we will need
to know what size
need. If you are going to use it in jewelry, most of our jewelers
$250-300/lb. size, so you would be looking at $125-150.00 for
a 1/2 lb."
This was all that I knew and I did say that I had never seen
I do not know what their return policy is, but if someone doesn't
reasonable one I would say don't do business with them (even priests
always be trusted etc.). I thought this might be worth looking
into, but am
very sorry if I led any astray.
I would say that for smaller amounts of nice material (or parcels
cases) you could try Jef Graham, http://www.cabbers.com/index.shtml
can try Morenci Stone Works, but the price on that has went up
indicate they want you to buy 2 lbs.
Right now you can buy some Chinese turquoise from Firemountain
http://www.firemountaingems.com/shopping.asp (type "rough"
in the search
box) it is 230 grams $89. This is up sharply from a short while
bought a little over a kilogram, at 260+ grams/parcel for $48
each ($192). I
was mostly happy with this (especially considering the price)
and got some
very pretty pieces out of some of this. Sleeping Beauty will not
give you a
break without a tax number, (1 lb. Minimum) but it dose sell by
Others sell this at about the same ounce price.
I will not say other suppliers that look vary interesting because
I do not
know their turquoise. Sometimes you can get a reasonable price
amounts from a rock shop you may know (such as 25-50 cents a gram
have talked to them). If you belong to a club or class you may
find the best
deal of all sometimes from members etc. (It pays to ask questions.
someone I will see in March at a show that has something I will
get. They have very nice Fox Turquoise at a better price than
the above and
I have seen it, they are not in busines.) Shows are also sometimes
sometimes venders will give the break. Shop around, spend time
on it, and
always be open, with good caution. I hope this may help someone.

From: email@example.com (Jack Denne)
"Keith" in New Zealand mentioned degreasing slabs from
saw cutting in
buckets of detergent. My mentor Bill Harris in Sarasota suggested
"Kitty Litter" in a pail. Worked for me for years.
Also I wonder if the hard opal might be the facet grade opal from
New Mexico? or Arizona?
Subject: Diamond heat sinks
Date: Tue, 12 Nov 2002 20:56:34 -0500
From: Fred Ward <firstname.lastname@example.org>
Patty asked about diamond heat sinks.
Look in the "Synthetics" section of my book DIAMONDS
and you will find both a short
discussion of diamond heat sinks as well as pictures of a couple
of examples of computer
chips resting on synthetic diamonds.
The reason for diamond heat sinks is that diamonds transfer heat
better than any other
material on earth. Given that capability, it was a short step
for our space program and
the military to look for ways to keep chips cool and operational
in terrible environments.
The first uses were with industrial grade naturals. Relatively
large synthetic diamonds
opened up a whole new world of possibilities. And then the latest
craze, carbon vapor
deposit (CVD) diamonds allow the manufacture of heat sinks in
almost any size and shape.
If you think back to the birth of really fast computers, the
early Cray Supercomputers had
their main electronics bathed in clean icy recirculating water.
Great solution for the
day; totally impractical now. Because diamond heat sinks can be
made in any shape or
thickness, they are designed specifically for individual chips.
It's a great use for
diamonds and a wonderful trouble-free heat removal device for
a huge variety of needs.

I remember the big splash when a Japanese firm let out,
several years ago, that they made 5+ carat single diamond
crystals for power transistor heat sinks and other such
uses. Pictures showed slabs of deep yellow diamond.
Problem in recovering used devices for a diamond is that
they mentioned military use in high-heat situations.

A major use for synthetic diamond slabs is to remove heat from
used in the telecom industry. The awesome thermal conductivity
greater than copper and electrical insulating properties of synthetic
diamond make them especially useful in electronics and physics.
While at University we had a talk from an engineer at MPR
Telecommunications. He told us that the lasers were as small as
a grain of
salt and sat atop a diamond and were housed inside a gold box.
He joked that
his boss thought they were opening a jewelry store.

Does anybody have a diagram for cutting a Princes Cut stone?
My wife saw
one in a jewelry store and would like one cut for herself.
Ernie Hawes published a copy of his interpretation of the Princes
cut in the New Mexico faceting
Guild Newletter. I have done the cut and it is nice. There is
also a Princes look alike in Data
View under square stones. It also cuts a nice chevron cut pavilion
and makes a nice stone.
There is at least one more variation of the cut out there that
also make a nice stone, but my
sometime remembering does not recall the name or where I found

Subject: Recutting stones
Date: Tue, 12 Nov 2002 22:08:14 -0600
From: "Wayne S. Barnett" <firstname.lastname@example.org>
The comments made on recutting poorly cut stones was interesting.
these stones I suspect are less than one carot in weight. Many
may be much
less. If so, recutting these stones makes no economic sense. Unless
is a special project for the recut stones or they are so bad that
cannot be used as-is, it is usually not worth your time to recut.
this is only my opinion. By-in-large I do not cut many stones
3 carots. If I have a special request I may recut a native cut
stone, but I
do not do the small ones. They are just not worth the time. If
we try to
correct all the bad cutting that come our way we will not have
time to cut
stones from the beginning correctly.
Some native cut stones can make good preforms though. Larger
stones can be
purchased in some cases at carot prices that are competitive to
of rough. This is especially true if the amount of loss is considered.
some of the shows I have seen cut stones actually priced lower
rough that it would require to cut a similar stone of the same
size. It is
difficult to compete in that market.
Keep up the grind.

From: "Steven W. De Long" <email@example.com>
I caught Jerry's post regarding the skill involved in recutting
stones and being able to have it make sense from a financial standpoint.
It was interesting because I just read an article from the July
of Lapidary Journal regarding recutting native cut stones.
A trick the author used to find the original angles of the native
was to paint the facet with correcting fluid whiteout and then
rub it against a ceramic lap covered with graphite (a trick often
lubricate a ceramic lap).
It seems to me a lot of the work involved is just figuring out
already been done to the stone (which could be pretty difficult
you could have facets placed at a variety of angles but still
adding up to a
standard shape) before you can even begin to access what to do
I personally would like to be accomplished enough someday to
a lapidary but I'm not particularly interested in re-cutting or
stones for a profit. I might be interested in it from the viewpoint
expanding my skills or for acquiring certain materials/qualities
difficult to find in the rough and re-cutting them for myself
I wonder if Jerry's points regarding the risks apply to damaged
It seems to me that their might be a source for damaged stones
that could be
purchased at a discount and re-cut at a profit.
A jewelry I dealt with a few months back (selling my first opals
interesting experience) suggested I could make a killing buying
stones in bulk ard repairing them (he had no idea how long it
takes me to
cut just one stone).
I like to know if that's a plausible idea.

A little old woman calling Mt Sinai Hospital says, "Hello
I'd like to talk to the person who
gives information regarding your patients. I want to know if the
patient is getting better, or doing like
expected, or is getting worse."
Do you know the patient's name and room number ?"
"Yes, darling. She is Sarah Finkle in room 302."
"Oh yes. Mrs. Finkle is doing very well. In fact, she's
had 2 full
meals, blood pressure is fine, blood
work is normal and she's going to be taken off the heart monitor
few hours and if she continues to
improve Dr. Cohen will send her home Tuesday afternoon."
"Thank God! That's wonderful! That's fantastic news, darling!"
"From your enthusiasm I take it you must be a close family
or close friend."

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
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."
