Platinum vs. White Gold: Which is Better?

The choice between platinum and white gold depends entirely on personal preference, which is why we offer our rings in both metals. At first glance, platinum and white gold may appear similar, but their differences become more apparent over time. Platinum is a heavier, denser metal, giving it a luxurious feel and exceptional durability. Over time, platinum develops a unique satin-like patina, which many view as a cherished symbol of their enduring relationship. In contrast, white gold will eventually take on a warmer, yellowish hue as its rhodium plating wears off. Due to platinum’s higher density, it is often considered more durable, which is why it’s crafted into rings with 95% purity for maximum strength and beauty.

How to Choose the Perfect Platinum Engagement Ring

Platinum’s bright and reflective appearance makes it the ideal choice for highlighting the brilliance of your lab grown diamond. When selecting your diamond, consider prioritising the 4Cs to enhance its beauty. Due to platinum’s brightness, we recommend choosing the most colourless stone possible to ensure it truly shines. If you prefer a step-cut diamond, such as an emerald cut, focus on a higher clarity grade, as its facets were designed to showcase the inclusions or “jardin” of a green Emerald stone. On the other hand, for brilliant-cut diamonds like round or pear shapes, prioritise a high cut grade—the scintillation and fire of these cuts hides the appearance of smaller inclusions. One of the many advantages of lab grown diamonds is that higher grades are far more accessible, allowing you to choose a larger and better-graded stone at a fraction of the cost of a natural diamond.
