When it comes to fine jewellery, platinum and 18ct white gold are two of the most popular choices for engagement rings, wedding bands, and heirloom pieces. While they may look similar at first glance, there are important differences between these metals, especially when it comes to upkeep, durability, and long-term value. With gold prices reaching new highs, many are now discovering that platinum offers greater advantages than ever before.
What Is 18ct White Gold?
White gold doesn’t exist in nature. All gold is naturally yellow. To create white gold, jewellers mix pure gold with other white metals like palladium, silver, or nickel. The resulting alloy still retains a slight yellow tint, which is why white gold is coated in rhodium, a bright white metal that gives it a crisp, silvery finish.
This rhodium plating isn’t permanent. Depending on how often the piece is worn, it typically needs to be reapplied once a year. Over time, the plating wears away and white gold can start to look dull or slightly yellow. Rhodium plating is an added cost to consider, especially for everyday pieces.
What About Platinum?
Platinum is naturally white and dense. It does not require rhodium plating to keep its colour and it won’t fade over time. Its purity, usually 95 percent, makes it hypoallergenic and ideal for those with sensitive skin. Platinum is also heavier and more durable than white gold, making it a preferred choice for securing diamonds and other gemstones.
When platinum is scratched, the metal isn't lost. It simply shifts, developing a soft patina that many wearers value for its subtle character. If a high polish is preferred, platinum can be professionally cleaned and polished without any need for additional coatings.
The Price Factor
Platinum has historically been more expensive than gold, largely due to its rarity and weight. However, with the price of gold now surpassing that of platinum, the gap has closed. In some cases, platinum may even be the more affordable option.
That means you can now enjoy all the benefits of platinum at a similar price point to 18ct white gold, without the added cost of ongoing rhodium plating.
The Bottom Line
While white gold is beautiful, platinum offers greater long-term value. It is strong, low maintenance, and keeps its colour naturally. You will not need to worry about annual replating, and your piece will last for generations.
