I was wondering if anyone happened to know what WG mixture (Nickel WG or Palladium WG) Macy''s uses for their fine jewelery? I assume that it would be Nickel WG, but I wanted to see if anyone knew for sure. My GF has a channel set 14K WG band from Macy''s that she has been wearing daily for 2+ years now and it is still very white and has never been re-dipped. I am getting a custom e-ring made for her in 14K WG, so I would like to go with the same mixture for durability/appearance reasons. I am getting it made throughand I can choose between Nickel WG and Pd WG (a little bit more). Thank you for the help!
