Hi all;

I hope this email finds everyone doin' well.  I was "Googling"
the other day for Gemstone sellers.  I was trying to find some "Mandarin" or
"Fanta" colored Spessartine Garnet.  I didn't have much luck findin' good
rough so I was thinkin' of buying Native cut stones and re-cutting them to
the proper angles.  I need a pair of about 4mm rounds for earrings, and an
oval in a 4X6, 5X7, or 6X8 for a ring stone.

Anyway, I found this website that has a LOT of useful info on
it.  There's a feature where you input a gems measurements, the specific
gravity and it will give you a carat weight of it.  There're tons of other
conversions, and calculating programs accessible from it as well.  I browsed
thru it for almost an hour.  It's really a useful link;

Check it out; I'm sure you won't be disappointed.

Take care all, do good,
todd of Todz Rox

Subject: New Product - Guiu Doppers

From: "Todd" <td_gunz@yahoo.com>

Hi again all,

I forgot to mention something in the other email I'd submitted,
so I'm doin' it now.

I recently got a device called Guiu Doppers.  They are the best
investment I've ever made in this hobby!  They were developed by Ultra Tec's
rep in Spain; Jose Louis Guiu, and called a Guiu Dopper.  Here's the link to
it from Jeff Graham's site;

http://www.faceters.com/equipment/dopping_acc.shtml

He's got the best pictures of it.  It's also available direct
from Ultra Tec at their site on the accessory page;

http://ultratec-facet.com/V2Accss.htm

It's designed to fit into a transfer fixture and you can "clamp"
a piece of rough into it and get it to dop right where you want to position
the material.  It does it perfectly, and without any headache of heating a
stone already dopped and shifting it slightly to get the best yield out of
your rough.  It's especially great for small costly rough like Montana
Sapphire, etc where a slight mis-dop can really ruin a yield on a stone.

There's one for Emerald stones too; which is notched out on two
sides so you can dop longer material like tourmaline crystals with ease. I
got the set of two and they're the best investment I've made.  I'll be the
first to admit I'm not the most adept in dopping.  This product seemed to be
tailor made for me and the problem I was having.

I heard a larger set was in the making as well and be available
soon.  The current standard Guiu dopper will hold a stone size to about 11mm
square.

There're 4 adjustment screws which grab the rough and by
loosening and tightening opposing screws you can move the rough back and
forth to get a proper position for dopping.  The base also screws up and
down so you can position the depth of the rough in the dopper itself.

I know my description probably isn't as good as Jeff describes
it on his site, so go there to look at the pictures.  Once I got the dopper
the concept was self explanatory, and easy to use.

Like I said, this is great for holding a piece of rough "just
so" while super glue or epoxy dries.  Jeff told me how to use it when
dopping with wax as I was concerned I'd melt the nylon screw which sets the
base depth.  Using his technique I've not even got the dopper more than warm
to the touch when dopping with his Red/Brown wax.  I've also had a LOT less
"pop offs" with this, as it stops the rough from moving while I get a good
wax joint between the dop and rough.

The price point is a little high on them, but I think they'd
easily make the investment back in higher yields on expensive rough.  Check
them out; I think they're the first product developed exclusively for the
faceting hobby.  It seems that most things in this hobby were "stolen" from
another industry and just happen to work for faceting.

One last thing.  I found out accidentally a great way to heat my
rough when I get ready to dop initially.  I dropped a piece of rough on my
electric coffee mug warmer I've got on the work bench.  When I picked it off
there, I burned my fingers on the burner.  That's when the light bulb went
off in my brain.  Setting the burner on hi I put a piece of rough on it and
in no time it was easily hot enough to help get a better wax bond to the
dop.  It heats up slow enough that it won't crack heat sensitive rough.  The
mug warmers are available online at any number of stores, and I even found
one which plugs into a USB port so you can keep your coffee warm while
browsing the net.

Talk about something being used in the trade which had another
application initially, lol.  I'm sure some of you "old-timers" have already
figured out that this would work, but it was new to me.

Sorry for rambling, hope you check out the Guiu Doppers.
They're very useful, or at least have been to me.  The usual disclaimer
applies; I have no vested interest in Guiu Doppers, Jeff Graham's site, or
Joe Rubin's Ultra Tec site.  I only wanted to tell you all about a new
product out there.

Take care all, do good,
todd of 'Todz Rox'

Subject: Facetting gemstones. A leap forward please

From: Brian Clifford <pesty@paradise.net.nz>

After all this talk about Jam pegs, cutting on glass, machines made out of
wire etc, I cant help wondering if we are all taking a great leap backwards.
With so little time available to me with all the pressures of work, and
still having to earn a living,  I am looking for an automatic facetting
machine. One with a computor, that basically does all the work for me.  I
know  that several companies off shore, mainly in Thailand, and now even
Australia use them, . Can anyone tell me where I can source one of these.
Cheers

Hi Tony

Just to let you know this has been happening for most of my faceting life.
I started cutting in 1965 and have been at it ever since sometimes more off
than on but for a good many years now.
-----------------------

Note to facters:

The Gemcad Web Page that I ran for a few years is undergoing a remake and if
and when I get it back on the web it will not be called anything to do with
Gemcad as I do not in tend to deal with the windows version.  Too much
politics involved.  It will (I hope) be a general help page to the faceting
community and will have some of the old DOS Gemcad pages in place.  I feel
that helping with problem areas of faceting is much more rewarding.  I never
did charge for any of the old page and don't intend to charge for this new
one either.

Larry

Hello I'm so glad I found this web sight and I hope you can get me started.
I've been a rockhound forever and I just purchased a Star Diamond
combination rocksaw,grinder and polisher and I'm not sure how to set it up
or the proper cutting proccedures. I bought it used and it has no manuals it
is a C6 model Series 6754. I would truly like to get started in lapidary
skills and would appreciate any feed back or information on where to start.
I believe that lapidary work should be kept alive and am very excited to get
going. Thank you for your time and I hope to hear from you soon.

Subject: Polishing Large Table

From: "Tom Wilkie" <twilkie@mounet.com>

I am currently trying to polish the table on a smoky quartz 43 mm
standard round brilliant. I prepolished with a very worn 1200 Dyna Lap. 
I have tried polishing with a cerium oxide Ultra Lap, with a Spectra
Ultra Lap, with .3 micron aluminum oxide on a tin lap, and with 50K
diamond on a ceramic lap.  So far I have put in scratches with the
ceramic lap, and made little progress with all the others.  I have cut a
lot of stones, but never one near being this large.  Is it a matter of
patience, or is there a technique for polishing facets this large?  I
will appreciate any help---I knew polishing the table would be a
bear--but not a bear this big and mean!!!!!

A mother enters her daughter's bedroom and sees a letter over the bed.
With the worst premonition, and trembling hands she reads:

"Dear Mom,



It is with great regret and sorrow that I'm telling you that I
eloped with my new boyfriend. I found real passion and he is so nice with
all his piercings and tattoos and his big motorcycle. But it's not only
that mom, I'm pregnant and Ahmed said that we will be very happy in his
trailer in the woods." "He wants to have many more children with me and
that's one of my dreams. I've learned that marijuana doesn't hurt anyone
and we'll be growing it for us and his friends, who are providing us with
all the cocaine and ecstasy we may want. In the meantime, we'll pray for
science to find the AIDS cure for Ahmed to get better, because he  deserves
it." "Don't worry Mom, I'm 15 years old now and I know how to take care of
myself. Some day I'll visit so you can get to know your grandchildren."

Your daughter,
Judith

P.S.



"Mom, it's not true. I'm at the neighbor's house. I just wanted to show you
that there are worse things in life than the report card that's in my desk
drawer............ I love you!"
