White Gold Engagement Rings

18ct white gold is an alloy of 75% pure 24ct gold and 25% other white metals including palladium and silver. While there are other white gold alloys available (such as 9ct or 14ct) 18ct is the most resistant to damage over a lifetime of everyday wear, and therefore the recommended choice for a white gold engagement ring.

Because 18ct white gold contains such a large percentage of pure gold, the resulting colour is an off-white tone. In order to achieve the desired bright white look, it is plated in another precious metal called rhodium. This coating wears off over time, so to keep your white gold engagement ring looking its best, we recommend re-plating every 1-3 years depending on wear and tear.

Although similar in appearance, these are actually two very different metals with very different properties. Both have their advantages and disadvantages, and your design choices can play a big part in determining which metal is best for your piece.
Our jewellers work with these metals every day and will be happy to guide you in your selection. For more details on how platinum and white gold compare, read our helpful guide here.

The hallmark for 18ct gold is 750. This represents the 750 parts per 1000 that is pure gold. You can find this hallmark stamped on the inside of all the white gold engagement rings we have made in 18ct.
