One question our jewellers are frequently asked is “which is the better metal between white gold and platinum?” The answer is not so simple. They both have their advantages and disadvantages and design choice can play a big part in which metal may be better for you.
Platinum is inherently stronger than white gold and the density of platinum means it wears away more slowly than white gold. Whilst its density can offer many benefits, it also has a few drawbacks. Platinum is a very malleable metal, and as a result it loses it polish quite quickly and square edges will begin to round off. Very fine designs may not be suitable, as the metal can bend out of shape, potentially losing stones from settings. In contrast, white gold maintains it polish for longer and is often a better choice if your design has square edges, an engraved surface or bevelled details. Also, it can be more rigid for fine designs and claw settings.
Another separating factor is colour. While platinum is a naturally white metal, gold is naturally yellow and white gold is made white by alloying it with other metals such as palladium. Because of the yellow metal content, white gold is slightly off white in colour. This can be corrected by a surface treatment called rhodium plating. Rhodium plating is the application of a very thin layer of a metal called rhodium that is electrically plated on to the surface of the white gold to brighten and enhance its colour. This plating wears off over time and needs to be reapplied. The length of time between applications can vary depending on the individual wearer, from weeks to years.
