Our Standards

Diamond Sourcing

Sourcing our Fancy Coloured Diamonds is a meticulous process and it requires years of trusted relationships with suppliers, from mine to market, and a discerning eye for quality that only decades of hands-on expertise can provide.

Fancy Coloured Diamonds cannot be purchased based solely from a certificate, they each have to be physically held and viewed in natural daylight to truly determine if it possesses the desired attributes and reaches our standards.

The Meticulous Process

Our In-House Workshop

Setting a Fancy Coloured Diamond requires careful consideration of how the gem interacts with its metal. Our in-house artisans have honed this craft over decades. For these diamonds, highlighting the diamond’s colour is essential to enhancing its beauty.

Pink Diamonds

Pink diamonds are incredibly rare and are recognised as the rarest among all fancy coloured diamonds. They are an extraordinary geological anomaly, the pink hues are thought to be caused by changes in the crystal structure. Pink diamonds make up less than 0.1% of total diamonds sourced globally.

Yellow Diamonds

Yellow diamonds are prized for their radiant, sunny hue, making them one of the most sought-after coloured gems. Their vibrant colour, caused by traces of nitrogen, sets them apart from traditional white diamonds, offering a distinct and captivating beauty.
