What is a platinum lab grown diamond ring?

A platinum lab grown diamond ring features a lab-created diamond set in a platinum band. Lab grown diamonds are real diamonds — chemically and optically identical to mined diamonds — at a significantly lower price point.

Why choose platinum for a lab grown diamond ring?

Platinum is the most durable and pure precious metal used in fine jewelry. It's naturally white, won't yellow or require replating, and its density makes it exceptionally secure for holding stones.

Is platinum better than white gold for a lab grown 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 does a platinum lab grown diamond ring cost?

Platinum lab grown diamond rings vary by stone size, quality, and design. Platinum adds a premium over gold settings. Contact our team for current pricing.

Can a platinum lab grown diamond ring be resized?
