Platinum Diamond Jewellery FAQs

No. Platinum is naturally white, so it does not fade, tarnish or require re‑plating. Over time, it may develop a soft patina, which many people appreciate for its subtle, matte character. 

Yes. Platinum is particularly well suited to everyday diamond jewellery, such as rings, studs and pendants, because it is resistant to wear and holds stones securely over long periods.

Platinum is low‑maintenance. Regular cleaning with mild soap and water keeps diamonds bright, and occasional professional polishing can refresh the finish if desired. 

Yes. Platinum’s neutral colour works well on all skin tones, providing a clean, refined look without overpowering the diamonds or the wearer’s natural colouring.

Like all precious metals, platinum can develop surface marks with wear. However, platinum does not lose metal when scratched it displaces rather than wears away helping jewellery retain its structure over time.
