I am planning on working with 375(9ct) gold very soon. There are varying tones from red gold up to yellow gold depending on the ratio of silver to copper. I plan to use what appears to be an industry standard yellow (37.5% gold, 42.5% silver, 20.0% copper). My concern is that anyone purchasing a pendant I made might have a 375 yellow gold chain with a different ratio of silver & copper.

  1. Is the difference between the varying yellow gold tones obvious?
  2. Has anyone here selling jewellery ever worked with 375 yellow gold and had a customer complain about the tone?



Thanks in advance.
