I love the stuff. It cuts easily, produces a very brilliant stone and is very
affordable. The one drawback is its hardness. A bit soft for a ring but
perfect for a pendant. It is of course a first cousin perhaps even sister to sun
stone. I cut a lot of it for family use.  Dennis on the North Coast

I do not believe there is any advantage of one over the other as far as
cutting is concerned. The difference is the surface area usable thus giving a
longer sweep and resulting surface speed helps cut a bit faster. I cut for years on
an old Lee and all it took were 6 inchers. My ultra-tec of course can take an
8 inch lap.  I would assume that your getting the two sizes is a result of
someone either having cut on a 6 inch unit and had the laps for it or decided
from time to time to save a few bucks and purchased 6 inchers. Just use them up
like I did. Using the "cheater" is easy on the ultra-tec. I recieved a "how
to" video with mine and have since loaned it out to several fellow faceters that
purchased used ultra-tecs. Perhaps they will sell you one or baring that let
me know and I will have the last faceting friend send the tape to you to use
to get started.  Dennis on the North Coast

To one and all:

I have not put the Gemcad Web Page back online as of this date due to
several reasons one of which is that I had been running the site and paying
all of the expenses of hosting etc. out of my own pocket.  Then when I
attempted to offer some of the site information on CD there were several who
accused me of stealing their ideas... Go figure.  My material was all of my
own writing but they thought it was stolen.  I am not one to point fingers
and this will be the last you will ever hear of this subject.  I am not at
all angry just mystified.

I am also burnt out and need some time to get my excitement back for the
page and faceting in general.  I will offer my help to anyone who is having
problems with faceting and or Gemcad if I know an answer.  If I don't then I
will do my best to find someone who will know.

There are a few "free" web page sites that I may put the Gemcad page back
online with but the last one would only allow one page (file) uploaded at a
time and now the MASS of files that are required to make the DOS version
site work.  Time will tell what I will do.  I hate to stop now but I haven't
finished a single stone in over two years now having only cut the pavilion
on one stone and it isn't even polished.  That was on a brand new machine
from my wife last Christmas a year ago.

As you get older (I am now 61) you seem to slow down.  In my early years of
faceting I would start cutting on Friday night and still be working on
stones come morning on Sat..  Not anymore.  I have Diabetes and loss of
feeling in my feet and some in my finger tips.  This may be stopped as I
have been keeping my sugar levels down religiously for some time now even
getting so low that I nearly passed out today while eating in a restaurant
with my wife (who is a well known head nurse of Dialysis in Wichita and
Kansas) getting down to the point that I could not hear here or the noise in
Applebee's which at noon was very loud.  I know that I was down to 49 just a
few minutes prior and my wife thinks that I may have been in the 30s even
the low side of that.  We got it taken care of very well and very fast.  No
more I hope.

Again if ANYONE needs help on Gemcad or faceting problems please feel free
to email me at ldavks32@cox.net

Ted, the best way to determine diffusion treated stones is looking at them
in an Immersion cell.  A heavy liquid of a similar RI is best, but baby oil
smells better and a lot safer.  Use diffused light and look for color
concentrations around the girdle and at facet junctions.  This is a dead
giveaway for diffusion treated stone, of any species.

These stones can not be recut.  They are treated after cutting.

Also with Topaz, and recently with tourmaline, the stones are coated after
cutting to give different colors and iridescent looks.  The same, or
similar process to the neon quartz crystals that were popular about 7 years
ago, and the blue quartz that is coated with a gold finish.  There was
recently an article on coated diamonds.  Who knows where this will stop, if

If you check the back issues of GIA Insider, you will run across a couple
articles on these treatments. There web site is

If anyone on the list has any info concerning our companiero Patty Miklik
please let us know. The last I heard from her was she let us know that the fire
was close to her but she did not loose any structures. I have recently sent her
a private hello email and recieved no response. Perhaps one of our Ramona

Spend the money.

The added features, and the overall display are alone worth the money.

Hi Don, and all other DOS GemCad users....

The advantages of Windows GemCad over DOS GemCad includes a more
intuitive and user friendly interface, and much easier navigation to the
different capabilities. Plus, there are some things which make life much
easier in the Windows version, such as being able to click on an "edge"
between facets and get information about the angular difference between
those two facet normals. Anything below 5* lets you know that facet will
"cut in" quickly. You also get information on the surface area of a facet
as a percentage of the width squared. Printing now also becomes much
easier, as well as pasting information between documents, since Windows
GemCad is a full capability Windows program. The DOS version required a
DOS recognized printer, but even if that problem was overcome, you still
didn't have a lot of the copy or paste capability and ease of
transferring documents between programs. Also, the "scale" and "center"
functions now actually work, plus seamless import of DataVue diagrams
(not part of GemCad).

I was a very avid user of DOS GemCad and had used it since the beta test
of the 80's. The only capability you lose by going to the Windows version
is the old "construction line" way of setting a point, which is much too
archaic for the Windows GemCad 8 decimal point accuracy (yes, I initially
resisted this loss of capability too, and even asked for a revision
[sorry Robert] but found if you diligently learn the program, the new
approach actually works better). To make up for that, the Windows version
offers a new "set a point in the exact vertical or horizontal direction
of the previous point" capability. True, there is a learning curve to the
new program, and some things are approached differently in the Windows
version, but now that I've thoroughly learned it, it is much more user
intuitive (which speaks well for the beta testers that provided input to
the finished product). Doing the tutorial lessons clears up these "new
approaches", and you'll reinforce what new you've learned by using the

Additionally, it's time to spend the $95 as a show of support for Robert
Strickland's years worth of programming effort for our faceting software,

Try it .. you'll like it.

Hi Don:

In response to your question about DOS and Windows Gemcad versions.

"Does GemCad for Windows offer any advantage over the DOS version? I am
comfortable with Dos commands (been doing this a long time) but get a bit
uncomfortable when it costs $95 if there is no improvement.

I am the owner/Editor of the now out of service (read "I haven't put it back
online") of the Gemcad Web Page site.  That site was dedicated to the DOS
version and ran online for several years prior to the advent of the GC
Windows program.  I have taken the site down for a while at least until I
decide whether to make a new version or add a Windows side web site.  I ran
the DOS site at no charge to Mr. Strickland in effect giving him YEARS of
totally free advertising and never asked for a single cent.  I also had to
buy the new version.

Now for your question.   Yes there are several great advantages to the new
program in that it offers you a single pass printing of your stone views and
directions without having to go through two different programs and print
passes.  There is another feature that I like very much.  It gives you an
"Isometric" view of the stone (three dimensional) which you can grab with
the cursor and freely rotate in any direction giving you the ability to see
the relationships of all your facets to each other.

If you like to work with the volume of your stones there is a neat feature
for that too but to tell you the truth I haven't figured it out myself.

These are just a few of the changes just from the top of my head but much
more is there than the eye can see at first glance.

BTW:  If you own the DOS version there is a discount for that too but you
seem to know that from your price quote.

If I can be of any further help just email me at ldavis32@cox.net

Mr. Dewey was briefing his client, who was about to testify in his own defense.
"You must swear to tell the complete truth. Do you understand?"
The client replied that he did.

Then lawyer then asked, "Do you know what will happen if you don't tell the truth?"
The client looked back and said,
