A researcher looks set to transform the jewelry industry after becoming the first to grow – a ruby in a ring.
Sofie Boons grew the gemstone from a “ruby seed” in situ – in a platinum ring.
Sofie is a Senior Lecturer in Design Crafts at the University of the West of England Bristol (UWE Bristol).
She grew the gemstone from a ‘ruby seed’ – which can be produced from discarded gemstones or waste gemstone materials readily available in the industry.
The jeweller-turned-scientist has spent the last four years developing the process to grow this waste material in situ in metal structures.
She hopes to use her groundbreaking research to change negative attitudes towards lab-grown gemstones and make way for a new era of using urban mined gemstones.
Unlike gems grown from scratch in a lab, which can be energy-intensive, or gems mined unsustainably from the ground, these gems require a flux solution to grow in a furnace from pieces of waste gem material or grit – a process that takes just days.
The lab-grown gems are identical to mined ones, with the same structure and quality – the only difference is where they have been grown.
Sofie says: “This is a completely innovative and more sustainable process that could transform how jewelers incorporate gemstones in jewelry, a process that is literally outgrowing traditional practices.
”Usually with chipped gems, jewelers have to cut them even smaller before using them, which therefore lowers the value, but this process enables them to use waste gemstone material to grow gems as big as they need, in situ in metal structures.
”I hope this innovation will put an end to the long-shared narrative that lab-grown gems are ‘synthetic’ or less valuable than mined ones.
”After all, these neo-gemstones grow following the patterns set by nature, resulting in stunning natural facets, which each time a seed is grown will be different.
“In theory, we have enough material on the planet today to stop mining. By sharing this research, I hope to put power into the hands of jewelers, as the technique is simple enough for them to adopt – it’s not just for scientists.
”I’m looking forward to expanding the research, looking at other gemstone colors and growing in different metal structures.”
Professor Elena Marco, UWE Bristol’s Pro Vice-chancellor and Head of the College of Arts, Technology and Environment, said: “Mining for gemstones has many environmental consequences, including soil erosion, deforestation and ecosystem destruction.
”The technique that Sofie has developed challenges the view of the mining industry that mined gems are superior and introduces a credible and more sustainable way of producing innovative jewelry pieces without the negative impact to the planet.
“As a university, we want to empower our students and staff to face and tackle climate and sustainability challenges, and support real-world research that can help to address climate change, biodiversity enhancement and the environment.”
Sofie’s work will be published next month as she concludes her PhD. She now plans to expand the research, supported by funding from a UWE Bristol Vice-Chancellor Early Career Researcher Development Award, testing the growth of multiple seeds simultaneously and growing in other metal structures, as well as test the growth of sapphire seeds with different colors in collaboration with the University of Bristol.
Last year, working in collaboration with Swiss company BREVALOR Sarl, she created jewelry pieces with the world’s first lab-grown glow-in-the-dark single crystal material.
Sofie’s research was undertaken as a Crafts Council Research Fellow at the university’s Centre for Print Research (CFPR) and was funded through the Expanding Excellence in England (E3) fund by Research England.
Fluxes are usually flowing agents – in this case, it is a chemical used to lower the melting temperature of aluminum oxide (which is what ruby is made of).
