Joy 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.

Véronique 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.
