Chipped Topaz ,How can I fix it?


#1

I have a 5ml oval cut Topaz with a very small chip in the girdle area. Is
there anything that I can do from my bench to repair it , or do I have to
take it to a facetor? Marjorie Australia

It probably needs to go to the facetor. If it’s a blue or white topaz-
don’t even bother. It would be most likely be cheaper to buy another
stone. Anne

I’ve had success with a bright boy wheel on flexishaft drill at very slow
speed. Also with a Tropical Shine 3-Way fingernail buffer. Use only #2
smooth surface followed by buffing with #3 side. Experiment first on
similar material.

What ever method of repair you use, short of having the stone recut, be
careful of the cleavage planes.

Topaz has a perfect cleavage plane. It’s possible to apply force paralle
l to the cleavage plane & split the stone into 2 pieces. Usually topaz
is cut with the cleavage plain 10-12 degrees off the table.

I don’t know of any way to look at a cut stone & determine the location of the
cleavage plane. Depending on the appearence of the chipped area it
ma y be possible.

Good luck!
