Hi Camila, Silver by itself will not be strong enough to whiten gold.
With silver alone you will get an interesting “greenish” color,
really rather pale yellow in the 14k configuration. Commonly nickel is
used to whiten gold. You can buy this alloy already prepared with all
the right properties to add to your fine gold. Nickel can
significantly harden gold in the 14k mode and more so in 18k. If you
want to get away from nickel totally, a paladium alloy will probably
be your best choice. I buy 18k paladium white gold already alloyed.
This stuff is a dream to set stones in. I find it easier the 18k
yellow. I hope this is some help. Bye, John…J.A. Henkel Co. Inc.
