Hi Thurmond & Digest Readers
A few weeks ago, there was some discussion on the digest about where to
buy diamonds. I seem to remember that there was a source recommended that
sold small diamonds with a choice of quality. I suddenly have a need
for a third of a carat size. Could someone please tell me the name
and address of that source!!

>Another question: if you have only a few rocks to be tumbled, which is
better - lots of filler, or very small tumblers?
I find that my tumbling seems to do better when I fill the barrel 3/4
full regardless of size. Any rocks,(gravel??), will serve as filler
unless you're doing very soft stones. Also it seems to go better when
you use stones of various sizes in the barrel.
A question for the group. I have several pounds of possible fire agate
still embedded in the rhyolite matrix that I dug it from at Opal Hill
mine in CA. Anybody have any tips on how to remove the matrix without
trimming/grinding each piece by hand??

Subject: Cerium Oxide

From: John <firstname.lastname@example.org>
I do not dispose of my Cerium oxide but when I am finished tumbling I pour
the solution into quart to half gallon bottles and it settles out in a few
I have been using the same mixture of Cerium oxide and Tin oxide for over
10 years and I just add a little more oxides to it to make it thick again
when I pour it into the tumbler hopper.
If you wait long enough it will dry to a hard lump and you can also break
it up and put the pieces in the tumbler and it works fine and gives me
a mirror polish. Make sure your containers are loosely covered to avoid
Why dispose of it also when it costs so much and like I said you can recycle it.
Subject: Polishes - especially cerium oxide
Date: Thu, 06 Mar 2003 20:59:27 +0000
I have been polishing stones both as a hobby and as a professional for
many (over 30) years. In all of that time, I have only used cerium oxide once
and was not at all happy with it! I too experienced the greasy mess and the
stones would not polish as well as I liked.
Normally, I use only diamond for polishing both cabs and faceted stones.
Why use anything slower? With diamond, you really do not have to worry about
the stone hardness and it makes cleavage much less of a problem!
As for tumbling, I generally use one of two materials, depending on what I
wish to polish (Of course, I use standard silicon carbide for the rough
grinding!). For most materials, I use titanium dioxide powder. It is about
the same price as cerium oxide but is much finer and is slightly harder, so
polishes faster and better. For hardness 8 and 8.5, I use aluminum oxide
powder. Again, it is about the same price as cerium (maybe a little more
expensive), but it works wonders. The aluminum oxide does not give the greasy
feel that cerium does, but is a lot harder on your drums. The titanium dioxide
is less greasy feeling but does act as one monstrous white dye for many
materials such as wood and cloth so do not get it on anything you want to keep!
(Titanium dioxide is what is used to make white paint white.) The only
exception to these is if I must tumble corundum. Then it is necessary to use
diamond for all stages and the cost is extremely high. I have found that, if
you have patience, it takes about 10 ct of diamond (for each of your 3 grinding
and one polishing stages) to grind/polish about 1 pound of corundum and it
takes about 4x as long as anything else! Good luck.

Subject: Wanted Recovery CD

From: "George H. Kaufmann" <firstname.lastname@example.org>
I know this message does not pertain to faceting but it is indirectly
associated due to the fact that we communicate with each other on this
list VIA the computer. If you decide this is not appropriate for this
list and do not publish it I will understand.
I have a HP Pavilion Computer, model number 6357 and the operating
system is Windows98. I upgraded the BIOS to the latest available and
have installed a 20GB hard drive. I have transferred all of the
programs and data files from the old 6GB hard drive to the new 20GB
hard drive. In the process of installing and deleting programs, on the
old drive, there are instructions left in the system registry that no
longer apply to the present programs on my hard drive. I have found
most of the information that should be deleted but not all of it.
I have tried to run my Recovery CD. but it does not recognize my hard
drive, either the old or the new one. I can force the CD to run and I
get a message that some of the original data the came with the computer
did not write to the hard drive. In fact none of the programs were
written to the hard drive. I have come to the conclusion that the
Recovery CD is defective and will not work.
What I need is a copy of Hewlett Packard's Recovery CD "HP#5011-6393 or
the later version,
HP Part # 5064-7560 which is listed at HP WEB site as "Part Not Order
able". Microsoft considers Windows98 absolute and does not stock
associated software any more. If any of the list members has a
recovery CD for my computer I would really appreciate a copy of it.
