Im passionate about building a brand that does diamonds differently, one that prioritises the planet first. My founding philosophy and true belief is that the future of diamonds is about curation, not contributing to the noise. Every gemstone and diamond sourced under my name has been curated for a specific purpose not just for a collection to sit in a safe. 


My entrepreneurial endeavour has been driven by the clients I work with and the shared passion we have from sourcing the impossible. We believe natural diamonds and gemstones are exceptional treasures of the planet and to acquire something so magnificent should be celebrated privately and uniquely through design and craftsmanship. Designing with a timeless but contemporary eye is a challenge but one that I enjoy pushing the boundaries in.


The house & brand I’ve built since 2018 is slowly evolving into its next chapter, but the founding philosophy will always remain set in stone.  Im excited to evolve and facet my own legacy in the diamond space, and I will leave it in a more sustainable state than when I started.
