Hi Everyone! Hope you can come up with some ideas that happened to a
piece of jewellery I made. Here’s what happened: I was commissioned to
make a custom ring using the customer’s opal (very nice) I cast the
main part of the ring and fabricated the bezel (in 10K) added a 14K
white gold plate to part of the ring and bead set four diamonds.
The ring turned out fantastic, my client was really happy. About a
week later I get a call from her and she says one of the diamonds have
changed color! I told her to bring it in knowing that she probably got
some mustard ect. under the stone, no problem! Wrong answer, I’m not
sure what has happened although I have a few ideas. First off, I
supplied the diamonds; my wholesaler I trust. The diamonds were an F
color SI1 stones, now the .04 ct looks like a deep yellow turning
towards brown. When I was drilling the holes to the stones I broke
off a drill bit in the ring, I eventually was able to grind out the
balance of the bit but if I missed any would that rust and discolor
the diamond? I have soaked the ring in soap and water and tried to
reach under the stones with a toothbrush but can’t seem to get any of
the discoloration off.
If you have any ideas on what happened please comment!
