Superior Gold Quality

We are devoted to using only the finest gold in our fine jewellery creations. The choice of materials in this industry can vary greatly, and we understand the importance of maintaining excellence.

We also refrain from practices such as hollowing out the interior of a band, which could weaken the ring's strength and durability. With our lifetime guarantee, you can trust that your jewellery will be cherished for generations.

Our commitment to quality means no cutting corners — unlike others, we use premium, durable metals like palladium to ensure lasting beauty and strength.

Only high quality platinum too, others may Reducing the platinum content in jewellery, using lower purity alloys.

Advanced 3D Mapping

To guarantee a perfect fit and enhance the longevity of your jewellery, we utilise cutting-edge 3D mapping technology to create an exact setting for each gemstone.

This advanced approach ensures a precise fit, allowing the claws to hold the gemstone securely and reducing the risk of a loose stone.

By taking the extra step to meticulously analyse each gemstone's dimensions, we can craft a setting that not only optimises the stone's beauty but also provides structural integrity.

This level of precision sets us apart from others who may rely on generic settings or estimate the stone's fit, potentially compromising the long-term durability of the piece.

Philanthropic Initiatives

As a family business, Cullen Jewellery is passionate about giving back and supporting those harmed by old-fashioned industry practices. The Jewellery industry is known for its negative impact on African countries and communities due to diamond mining exploitation — and we are determined to do things differently.

In addition to not using mined diamonds and other mined gemstones, we aim to help rebuild these communities and create a better future for those who live within them. We do this by supporting humanitarian organisations and providing marginalised communities with funds, nutrition, shelter, healthcare, education, and employment to help break the poverty cycle.
