I hope that you can help me. I just made a ring for a friend of mine
in 14k yellow gold. The gold is from a very reputable company that
serves the pacific northwest. It was cast in the shop that I work in.
I did the polishing and my co-worker set the stones. My friend wore
the ring for about 1 week and complained to me that her finger was
turning green. I suspect it was more black than green, and when she
showed me I could see nothing, but she assures me it was much worse
the day before. Now I have seen this in customers from time to time,
fingers turning black from 14k gold, but they tend to have that
problem with all 14k. This friend of mine has at least 2 other rings
that she wears daily that are 14k as well as earrings and chains that
do not turn her skin colors. Is this a fluke? What should I recommend
to her? Is it something I have done? I could only find on the forum
info on silver discoloring fingers, but not gold. I must confess to
being a bit mortified, she and her husband are thinking that I have
somehow given her an inferior product.
Any help, suggestions, or consolation out there?
