Hi Brian & list,

Do you mean San Carlos peridot from Arizona?  I have not heard of the
peridot from San Pedro.

For my money the material from Pakistan is the best. The San Carlos
peridot tends to have brownish overtones I don't care for, and it
doesn't come in very large sizes. Also tends to be more of a problem
with polishing. The African mmaterial & the Burmese tends to be more
included.

Richard Hughes has a good article on peridot at:

>2/  A point to debate. Have heard that the San Pedro peridot is the best
>in the world for facetting, but the odd person says the Kashmiri, and
>Burmese is better. What do the people think

   Can anyone tell me if Doisite can be heat treated to turn it into
Tanzanite?Or possibly close to Tanzanite color?
   I have heard it is possible,but i don't know where to start.
If i am mistaken please feel free to inform me.
  Sincerely,Tom Miller

We were cleaning the shop and shifting inventory around prior to
starting students for the Fall and found 2 dozen new Riker mounts as
listed below.
The classified link did not have a category for them so I am listing
them below.  Anyone interested in them can contact me offline.

Bob Edgar - GSJ Lapidary  Yardville, New Jersey


12  -   8 x 14.5 inches normal retail around $10 sell for $6.50 each
 9  -  12 x 16   inches         "         "  $10     "    $5.00 each
 3  -   6 x 5    inches         "         "  $4.50   "    $3.00 each

The total for all 24 is $132.00  -  we would make it an even $130.00 if
you take them all. We have one small slightly used one we will throw in
for free!

These prices are cents away from our cost - we are just trying to 'blow
them out'.  Shipping is extra, of course, and we take major credit cards

Does anyone use , or know of anyone who uses the Diamante facetting machine
to facet diamonds. Are these machines any good, are they easy to use, etc I
would like to know what laps are used, and how to preform the diamonds for
cutting. Also how long one would expect a ,say ,1 ct diamond to take to cut
and polish

Dear Friends,
    I picked up some old lapidary equipment and one piece is a unit with
two diamond wheels attached to the front of it, flush with the front. It
looks like an old radio. Can't read the label anymore. Anyway, the
diamond laps have some light rust on them. Any ideas for saving them or
is this really a problem?

I know that it has been posted before but I can not seem to find it in the
archives.  Does anyone know the location where I can download a copy of
dataview, the libraty of facet cuts?

Thanks

Wayne
