Replacing the prong completely with new 20K wire looks like your
I would suggest completely filing the prong away, all the way to the
bottom of the setting, then laying in a new replacement wire in 20K,
laser welding in place. This way you will not have any joint within
When I do this type of repair, I prepare the new wire, leaving it
longer on both ends, so I can hold the new seat in place while
welding the bottom of the wire. I then finish welding, and trim the
prong top and bottomto match.
I am doing a similar repair today on a two tone 18K Fancy Yellow
Diamond ring that has had two prongs crack at the base of the
setting (not one of ourrings, but one I have been asked to repair),
although in this case I have removed the stone, cut off all 4 prongs
and am in the process of drilling the base of the setting so that I
can weld in all new 18K yellow wire for the replacement prongs.
Not being in Canada I am sure someone closer can help you, but I can
do this if you can not find someone more convenient.
