Steve,
  I have excellent luck polishing Picasso Marble on diamond.  I use 600,
14,000, then finish on 50,000.  I use it on Johnson Brothers resin pads,
but almost any pad would work.  I hear that south of the border the
Mexicans polish on denim and diamond.  I Have never tried it, but it
would be cheap.

If it's soft, it ain't jasper, which is 7 by definition. I have seen both
rhyolite and marble sold as "Picasso Stone", and both can be porous and difficult
to polish. You may never get a glassy polish unless you stabilize (i.e.
impregnate) it somehow.

All,
 The smallest stone I have ever facetted was .75mm in a full cut
Standard Round Brilliant with facetted girdle.  I did this just because
someone said that I could not do it back in my stupider days.
  Now I still cut a quite a few 4-6mm stones, mostly rounds.  Some
stones in small sizes will take a lot of facets and some will not.  I do
an 85 facet 5-6mm round in topaz and tourmaline that is outstanding.  Do
the same cut in sapphire or beryl and it looks terrible.
  For most small stones if you want to back off the number of facets I
would concentrate on making a sort of Zircon cut.  Cut say 8 mains and 8
breaks with the breaks extending almost all the way to the culet.  On
the crown I would cut any arrangement that was easy with an angle of 35
degrees for the mains.

Hi All, I recently purchased a Digital Camera.  That is quite a leap for a
Scotch/Irishman over 85.  I have searched the web for information but with
little success. I don't want to become a professional cameraman, but would
like to know how to set up lighting etc. to be able to photographk some cut
stones. Could anyone help me? Would really appreciate any help. So I will
thank you now!  Best Regards.   Webb in the Evergreen state.

howdy,
   Thanks to all who answered my question about the Facetron upgrade to the
dial indicator, both on list and off.
The opinions ran 100% in favor of the upgrade.

thanks,
Jerry

Answer these questions before checking answers below.


1) You are competing in a race, and overtake the runner in second place.
In which position are you now?=20

2) If you overtake the last runner, what position are you now in?

For this one, don't take any notes or use a calculator. Remember your
replies must be instantaneous.

3) Take 1000. Add 40. Add another 1000.
Add 30. 1000 again. Plus 20. Plus 1000. And plus 10.
What is the total ?

4) Marie's father has five daughters:
1. Chacha
2. Cheche
3. Chichi
4. Chocho
5. ????
What is the fifth daughter's name?
.
.
.

.
.
Answer 1) If you answered that you're now in first place, then you're
wrong.
You overtook the second runner and took their place, therefore you're in
second place.


Answer 2) If you answered second-last, once again you're completely
wrong.
Think about it. How can you overtake the person coming in last? If
you're behind them then they can't be last.


Answer 3) 5000??? Wrong again! The correct answer is 4100. Try it on
paper.


Answer 4) Chuchu??? WRONG! It's obviously Marie. Read the question
again.
