We use an alloy called Vanilla White from Argen out in California. It is a 14k alloy, very white in color, eliminating the need for rhodium plating.
This strikes me as an example of the difficulty, one might even say
stupidity, of “colorful” marketing terms. I would have thought a
white called vanilla would be a slightly yellow-tinged color,
perhaps an attempt to interest buyers in the color “white” gold is
when it isn’t really white! You know-- like vanilla ice cream!
If it were a way to market pale yellow gold, it might have been
interesting, since I’ve never heard of there being any interest in
that and it could add to the possibilities of color use if it
succeeded.
My interest is totally academic-- I haven’t ever used white gold so
far (except for the clasp of my now-famous bracelet, at Jim
Binnion’s suggestion). If I decide I want to use pale yellow
(“champagne”?) gold, og course, I certainly will do so, regardless.
