So you know that you want a white metal band. But what metal alloy should you use? What is the difference between palladium and white gold, and which one is more durable?
14k white gold and 14k palladium white gold both contain 58.5% pure gold, but are alloyed with other metals to make them more white in color. 14k white gold contains gold, nickel, copper, and zinc. Whereas 14k palladium white gold contains gold, copper, silver, and palladium. 14k palladium white gold does not contain nickel, which is a metal allergen for a lot of people.
950 palladium (also referred to just as palladium) is 95% pure palladium, and is a “white metal” that is slightly more gray than platinum or sterling silver. Palladium is in the platinum family, and shares many characteristics with platinum – durability, tarnish resistance, and is hypo-allergenic. It is about 1/3 the weight of platinum (it is comparable to the weight of 14k white gold), and about 1/3 the price of platinum. It is a precious metal, and in addition to being used in jewelry, has often been used in catalytic converters. Its use in jewelry is a newer application for this metal, so not all jewelers and jewelry repair shops feel confident working with it yet, but that is quickly changing.
14k white gold is a hard and rigid metal that is more resistant to scratching than palladium or platinum. Even though palladium and platinum may show scratches and dings earlier than in gold, with palladium no metal is removed when scratched, just displaced. Whereas a gold band will become thinner over time because the metal is slowly rubbed away over time. By comparison, we would say that in the first year, a palladium band will show more signs of wear, due to the evidence of scratches and dings. But, in 20-30 years, the 14k gold band will be thinner than it was originally, whereas a palladium or platinum band would retain its original weight.
