Precious Metals Guide

Our diamond rings and jewellery are available in Platinum and White, Rose and Yellow Gold.

The gold used in jewellery is ethically and sustainably sourced from small alluvial gold mines in New Zealand's South Island and is cast by a NZ-based precious metals bullion company.

Platinum Platinum

Platinum is double the density and weight of gold and is ideal for precious jewellery and large diamond rings.

As one of the rarest elements on earth, it is the least reactive metal and is great for sensitive skin since it is hypoallergenic.

Found in copper ores, mainly in South Africa, platinum exudes a cool lustre that complements the sparkle and fire of well-cut diamonds.
