Our rough diamonds

We selected a rough grower whose ethical commitments and credentials matched our own to ensure absolute customer assurance at every stage of the pipeline

Cedia Commitment

Since 2022/3 our diamonds are entirely sourced from the USA

Since 2022/3 our diamonds are sustainably grown using 100% renewable energy

Our diamonds are grown using the less energy intensive CVD (chemical vapour deposition) method

All our diamonds are all type IIa, with high purity and high optical transparency.

Production Reality: Not all lab-grown diamonds are eco-friendly. They imitate the natural diamond formation process, demanding significant electricity, largely from the national grid. China and India produce over 60% of lab-grown diamonds, utilizing coal for 63% and 74% of their grid electricity, respectively. (Natural Diamond Council 2023) Additionally, pipeline transparency and labour conditions in those countries can be cause for concern.

Our customers value our consistency in production and supply, yielding a uniform assortment quality. Our polished outcome is completely without the brown tint that is a common occurrence in goods from other suppliers
  • OVER 70% OF PRODUCTION IS VVS + IN QUALITY
  • CUTS ARE AVAILABLE FROM VERY GOOD
  • DEF, GH & IJ IN COLOURLESS GOODS AVAILABLE

Round, Fancy and Proprietary Cut Development

Our specialism is developing proprietary cut and fancy shapes that are optimised for performance and beauty. Each proprietary cut has a clear and visual benefit that can be supported with a succinct narrative.

Special Shapes - Exploring new possibilities in diamond

A key advantages of LGD technology is the liberation it offers to us in shape exploration. This new diamond rough has allowed us to push the boundaries of design creativity without the constraints imposed by traditional factors such as yield, cost, formation, and consistency. Previously off-limits shapes are now within reach, empowering us to craft unique, innovative designs that not only captivate and inspire but can deliver core branding and iconography to consumers.

Three stage chain of custody

Trust and transparency are core to the services that we offer. A short chain of custody and vertically integrated production processes mean that our polished diamonds only have 3 stops on their journey to the final customer.
