About us
Who we are
Truly Precious is a Dutch non-profit foundation (stichting) established in Amsterdam in 2025. We were founded by four jewellery professionals who share a conviction: that sustainability in the jewellery industry needs more than good intentions. It needs shared knowledge, honest dialogue, and collective action.
The jewellery supply chain is vast and fragmented. Behind each finished piece lies a complex network of actors — from miners to traders to retailers — where transparency and accountability remain the exception, not the rule. Sustainability knowledge is increasingly visible but also increasingly confusing. Companies are navigating growing consumer expectations, regulatory pressure, and fragmented information.
We believe the industry needs more honest dialogue and less isolated effort. Truly Precious exists to research, collate, and simplify sustainability knowledge — making complex information accessible to every stakeholder across the supply chain. We connect the dots so the industry can act with confidence and impact.

Why It Matters
Sustainability in jewellery is increasingly visible — and increasingly confusing. Companies are navigating growing consumer expectations, regulatory pressure, and fragmented information. At the same time, meaningful progress requires acknowledging contradictions, data gaps, and structural limitations.
We believe the industry needs more honest dialogue and less isolated effort. Our work aims to highlight real challenges and knowledge gaps, connect organisations working toward responsible sourcing, strengthen a global community built on knowledge and transparency, and create shared language across the sector.

- JoyCo-Founder, Treasurer - Board of TrusteesJoy Harvey is an artisanal independent jewellery artist with a focus on sustainability and responsible sourcing. In 2021 she co-founded la luce, her jewellery studio, which blends traditional artisanal techniques and a conscious and controlled supply chain. From Fairmined gold and silver to renewable energy she believes that every company should strive to have a positive impact on the planet and the people. For this reason, la luce has become a certified B-corp in 2024. Each piece she creates is one of a kind and completely handmade in her Italian studio. Her jewellery has been recognised in the LVMH Mestieri D’Eccellenza prize (finalist) and the Boghossian Foundation Jewellery Prize (winner) in 2024 and she was awarded the inaugural Vacheron Constantin and the Metropolitan Museum of Art artisan residency in 2025.
- VéroniqueCo-Founder, Secretary - Board of TrusteesVéronique Ribbink is a jewellery designer and maker, based in Amsterdam.
Her journey to jewellery design began unexpectedly. Initially a successful conference interpreter, she made a career shift after completing a goldsmithing course. Véronique then apprenticed under renowned goldsmiths and optical diamond setters. She went on to study Jewellery Design at the University of the Arts in London.
In 2023, Véronique launched her own jewellery brand, Eve Sparkles, where she creates unique, high-quality pieces and small, exclusive series. Her designs feature golden rings, bracelets, and earrings, meticulously set with sapphires, spinels, and garnets of all colours. Every gemstone is carefully sourced, ensuring an ethical and transparent supply chain.
Véronique’s approach to jewellery goes beyond aesthetics—she seeks to bring happiness to everyone involved in the process, from the miner to the wearer.
