They use a purple marking pen to dot location. The ink can thin and run
What a relief! I was worried, based on your original description.
I can't imagine why white gold would be the preferred alloy - American white gold usually contains nickle. The rhodium plating might help, since it would isolate the nickle. However, I would go for the basic alloys: 75% gold, 12.5% copper, 12.5% silver.
