Cutting Louisiana Opal


#1

Hello All

Was wondering if anyone has any tips on cutting Louisiana Opal, Some
of what I have is full of fire but a little grainy and I have damaged
stones setting them, it seems that a grain of the quartzite( or sand,
how ever you look at it). Some have said brush superglue on it, any
suggestions wil be welcome.

Thanks JW

how this can be achieved

there was an article in lapidary journal, or perhaps rock and gem,
about 7 or 8 years ago, on this location.

sealing is a good idea, especially if it is a sandstone base. you
can use either opticon, or cyanoacrylic (crazy glue). if you have
access to one, use a vacuum chamber to pull all the air out of the
sandstone, let sit at high vacuum for 24 hours before immersing in
opticon.

another method is to make a 2 piece intarsia, using a tough material
as the backing (agate, whatever) then the back will stand up to
setting.
