On your Idaho star garnet material, I understand
that the easiest
way to orient large complete crystals is to consider each flat as
potential base for a cab. The apex would be cut with the point
at the center of the crystal.
If they are good star garnets they are probably
'way too dark to be
We have a talk to our club mid-month by a fellow
who has collected
and worked central Idaho garnets for year. I will try to share
tips I pick up from his presentation.

I would like to thank everyone that responded to my questions about
sapphires. I learned a great deal more from this forum then I did
the books I read. It was explained much better. I am new to the
gemstones and most of my efforts have been directed at faceting.

Subject: what machine?
Date: Fri, 7 Feb 2003 22:44:57 EST
Hi! I would like to give a thought to Cheryl ... having been
through it, I
think i learned one thing clear: don't lapse on laps.
Since you gave no idea how much $ you want to spend, this may be
but near as i can tell after some experience and much reading of
every major, well-known brand of machine from a Graves to a Facette
users and advocates- all of whom produce very loverly gems.
But largely from
experience, also from reading, NO ONE produces very loverly gems
laps. I had the great idea that i would start with a great
machine and get
good laps latter ... if you have the budget do both now, but if
limited, please do thyself a favor and be sure the basics are covered.
For what it is worth, i have found that, for me, dyna disks are
fine up to
600 grit ... one solid steel Crystallite 1200 is worth its weight
For prepolish i use a copper with 8k diamond, for polish you just
a BATT lap for many materials... i my weak opinion. Minimum
i think would be
a dyna-disk 360 (first any 180 you can get cheap for very rough
large irregular rough, but not necessary) ... a Crystalitte 1200,
a BATT lap.
Hope you enjoy the art!

Thurmond, I have luck polishing turquoise on a buffing pad dry using
also works quite well on lapis. I used cerium on a leather pad for
until i noticed this working while buffing a ring with a stone in
Dennis on the North Coast
Hi Dennis, Some one at my local club suggested Zam as well. I will
get a bit to try out.

I have good luck polishing turquoise using Cerium oxide on swede
Run at slow to medium speed and keep wet. If you get in a hurry
the pad dry out you will get orange peel. Run slow & wet and
you will get
a good polish. I hope this helps.

Thanks Bud, I have already learned about orange peel the hard way.
I will give it a try.

From: Jeanne Ring <email@example.com>
I use this set up for all soft lapidary rocks including Turquoise
Some years ago while I was hunting Washington State green Opal I
into Golden Eagle Jewelry in Lewiston Idaho. I noticed in his shop
added a washing machine motor to a old Gem Pro or similar.
It had a one
piece aluminum flat lap with sleeve that screws on to the
shaft. It hums around like a washing machine with a nice slow rotation.
I talked him into building one for me. I use Zam green on
on a black sponge rubber back. I can really push the stone into
canvas if I want to. I've tried a lot of different combinations
used Zam on leather for some of the tough ones. I have tried spray
diamond and every thing under the sun and some worked fine. However
Zam on different grades of canvas was my overall favorite.
I assume you
used something like Opticon to stabilize your turquoise. The Zam
slow speed works very well on the Optician and also that Washington
State Green Opal with red or white ribbons and wisps in clear
peridot/bronze kind of color that I was looking for.
I scored about 370
pounds from a road cut near Spokane. I've had a lot of fun with
Jeanne in the N.W.
Thanks for the information but now you have me coveting some of
that opal. :)

I would like to know the element that gives the blue color to sapphires.
Now, I know they are corundums (Al2 O3) and I know
that the red
coloring element for rubies is chromium........but what is the element
that gives sapphires their blue color. I don't think
cobalt..........that IS used in synthetic sapphires......but I am
inclined to think it is titanium. I'm just not sure
of anything at
Can anyone out there help??

Subject: Question on pricing

I need some advice, and am really hoping
you'll share your experience
and professional insights on this situation with me, if you have
Normally, when someone asks me to perform
lapidary work for them, they
either do so because they've damaged a stone and need it repaired,
because they've purchased a rough and want to have it cut for the
time. Recently though, a jeweler came to me and asked me to use
resources are necessary to first locate a series of (colored stone)
to cut specific sizes and shapes, and then cut these for him, for
he's putting together...
Here's my quandary: how do I effectively
charge for the fact that my
time, my business contacts, my networking (to find and then negotiate
new contacts), my pricing/negotiating skills, my gem rough grading
gemstone-cut designing abilities and, of course, my cutting are
used here, _before_ any stones are even placed in the jeweler's
can I both come out ahead on this _and_ still provide this client
means to bring his product to market, cost effectively. To put things
some frame of perspective, I should probably mention that the stones
question include very high-end Rubies, Pink and Blue Sapphires,
Spessartites and Rubellites, all in sizes over 4 Cts, each!
The options that've occurred to me, so
1) Charging a higher "flat rate" per finished stone
(though this would
place the same value on a $400 Pink Tourmaline as it would a $4,000
and wouldn't compensate me evenly, for the R&D time needed),
2) Charging one fee -- an hourly "consulting" rate
-- for the R&D time, in
addition to my normal cutting charges. (though such an arrangement
necessarily not work twice, since my new sources would already have
developed and, therefore, I'd be doing more legwork for less pay,
doesn't sit right with me), or
3) "Charging" the client an equal piece of rough for each
piece that I'm
procuring for him, so that _my_ inventory grows at the same rate
does. (Although I've used a similar method for payment, called "cutting
shares", when others have brought me large lots of gem rough
to be cut,
doing so with this client will mean [to him] that his costs for
will be 100% more than the actual costs of the rough. while this'd
lesser roughs, how do I keep the client _as_ a client, when the
skyrocket, on such things as fine Rubies and Sapphires?)
...So, you see the quandary! How do I present
the client with both a
cost-effective means of getting the quality of color and cutting
at a price he (and his custoners) can afford, without cheating myself,
the process? I realize that several of you are out of town at shows,
moment, but if you could address this when you return, it'd really
great deal to me. In case it needs to be said, here, my challenge
provide a means of taking advantage of this opportunity, without
advantage" of my customer (or appearing to do so). Thank you,
for your consideration and insights.

The geology poem
Ode to Olivine in Thin Section, a poem by Brenna Lorenz
In basalt a lurid green
Bespeaks the savage olivine;
Mantle's child, born of fire,
Restless in the open air,
Little beads of anger bear
The torture of desire.
Silica upon its face
It suffers, helpless, in disgrace,
Its powers of reaction bound
By solid's bond and cage,
In agony confined to rage
Unstable and unsound.
Its birefringent power plays
The sifted light to rare displays;
The haunting, primal colors tell
Of fire and fury's flag unfurled,
Flag of fluid, nether world,
Beneath the fragile shell.
REFLECTIONS AND TIDBITS:
" I hear, and I forget.
I see, and I remember.
I do, and I understand."
