Choosing platinum lab grown diamond engagement rings

Our platinum lab-grown diamond engagement rings pair white lab-grown diamond centre stones with 950 platinum, which contains 95% platinum. Its naturally white colour gives the diamond a cool backdrop without relying on rhodium plating for its colour.

A solitaire keeps attention on the centre diamond, while a bezel frames its outline and a shoulder-set design adds detail along the band. Compare the diamond shape, band width and setting height together when choosing the proportions of your ring.

Platinum can develop a soft patina through everyday wear. Some people enjoy this finish; others prefer a brighter polish. A jeweller can assess the ring and advise on refinishing and checking the setting. Remove your ring for heavy work and follow the care advice for your chosen design.

If you are comparing white metals, explore our white gold lab-grown diamond engagement rings. Consider the finish, feel and ongoing care of each metal, and ask our team to check how your preferred wedding band sits alongside the setting.

Compare actual band and basket profiles

Look at the specified platinum fineness, band width and depth, then compare the ring’s weight and comfort where available. Platinum does not make every mounting identical: a fine band and a broader profile can feel different on the hand.

Designs to compare

A question worth asking

Does platinum mean a ring cannot scratch?

No. Platinum can develop surface marks with wear. Check the chosen finish, care advice and setting rather than treating the metal name as a damage guarantee.
