Another Tiffany Key question

[elle_chris]

So i'm addicted to Tiffs key pendants. I love, love, love them and have purchased two in the last few months, one in platium, one in rose gold. Now I want to purchase a much largeer 2.25' in white gold. Does anyone know if Tiff's uses nickel in their gold? For some reason, I never remember to ask when I go.
