Why choose a platinum natural diamond engagement ring?

Platinum is the most durable and pure precious metal used in fine jewelry. Combined with a natural diamond — a unique product of billions of years of geological history — a platinum natural diamond engagement ring is the ultimate expression of lasting quality.

Is platinum better than white gold for a natural diamond ring?

Both are excellent choices. Platinum is naturally white and won't require replating; white gold needs periodic rhodium plating. Platinum is also denser and more durable. For long-term wear, platinum is the superior choice.

How much more expensive is a platinum natural diamond ring vs. white gold?

Platinum rings typically cost 15–30% more than comparable white gold rings. Contact our team for current pricing on specific styles.

Does platinum scratch or tarnish over time?

Platinum doesn't tarnish. When platinum scratches, the metal displaces rather than being lost — over time it develops a natural patina. It can be polished back to a high shine at any time.

Can a platinum natural diamond engagement ring be resized?

Yes. Platinum engagement rings can be resized. Best Brilliance includes 2 free resizes per ring within the first year of purchase.
