Attack will not harm pearls, but it sure raises hell with the synthetic
ones.  Heat is your best option though.  grasp the peal with your
fingers.  Now heat the mounting , but keep the torch away from the
pearl.  Just about the time the pearl is getting uncomfortable to hold, the
epoxy or glue should release.  twist and pull the pearl.  Just remember,
the metal is a lot hotter than the pearl so make sure you have a hot pad to
hold it for the separation.  You need to be careful here.  It is possible
to overheat and burn or discolor the pearl.  If you have multiple pearls on
the piece, you have to watch that you are not damaging the one(s) that you
are not pulling right then.

Subject: Copper laps.
Date: Mon, 28 Apr 2003 21:26:19 -0400
To: lapidary@caprock-spur.com (LapidaryArtsDigest)
From: "Jonathan L. Rolfe" <webmaster@gearloose.com>

Copper laps are a good old workhorse, but serve best as prepolishing laps,
unless one is working with very hard materials like sapphire.  I chose
copper for the outer band of the Redwing (
http://www.battlap.info/redwing.html ) because it was the best choice for
prepolishing with 4,000-8,000 diamond. (It sure was not chosen for COST
reasons!)  Some people have had me make inlaid combination laps with BATT
in the center of cast iron, but all considered I prefer copper, though I
recall in the '70's one could not go into a rock shop without seeing cast
iron laps for sale.  They work well, especially with oil and diamond for
polishing sapphire, but they RUST.
Copper has an affinity for diamond and is workable enough to allow diamond
to be rolled into the surface.  I have some copper laps here that are more
than twenty years old.  They represent a good bargain in price/performance,
can be charged with a variety of grits from 320 or coarser to 14400, and
last forever.  With proper charging and maintainance their cutting speed is
not much slower than the plated laps.

Howdy Dale,
When the Jemeters (analog and digital) show up on eBay they go quick
and for big bucks.
I think Hanneman sells a version but the best deal may be the relative
reflectance meter at www.kassoy.com . Haven't checked lately but it had
been on sale for about $150. You need to refer its readout to a chart
but it operates on the same exact principle as the Jemeter.
There is also a Brewster's Angle meter available from the GAGTL that
can read up to around RI 3.5 I think. But it's about $1800 (or maybe
pounds now I think of it!).

Howdy Don,
Just a few weeks ago there were several posts about this on the Orchid
Digest (www.ganoksin.com). Try searching their archives.
The most intrigueing solution I recall was to use a
'soft'solder(electronics type) soldering iron, tinned with a little
solder, to hold on the post(fluxed?) in the pearl and unplug the iron.
When the solder was solid, the heat on the glue coupled with the
(hopefully) mechanical connection to the post, should allow it to be
pulled free. Of course, this assumes the pearl has been cut or broken
free of the base.

Hello,

Circumstances have forced me to sell a machine I've only had for a few
months, which was purchased new. It's only cut a few stones and comes
with dops and 2 laps, (cutting lap and a fast lap) plus the original
tools. Will negotiate price with or without rough; also I'll drive it to
where you are in the lower 48. Asking $4000/ or best and can accept PayPal.

Hi Everyone: Along with the nine speakers and two special guests
lined up for the Faceters Symposium 2003 at Ventura in June, we
have some great sponsors for our Hospitality Hour.  They will be
there to show their wares and talk to our interested Symposium
attendees. Along with Ultra-Tec and Facetron, we now have a 
third sponsor....Don Roberts.  Don will show you his skill and
equipment for cutting CONCAVE FACETS.  He is a distributor of
Poly-Metric OMF concave faceting machines and Xristal-Tek and
Scintillator flat faceting machines and accessories.  Don will have
the OMF (Optical Magnified Facet) unit at the Symposium.   If you
have not requested the packet of information as yet, time is
growing short.  Email me your snail mail post office address and I
will send the packet out to you PRONTO! If you intend to enter
the competitions we offer at the Symposium you had better get
your stone done soon.  There are not too many days left until the
Symposium begins. And, if you have not sent in your $90 for the
three days of the Symposium, better get that done soon too.
