Peter is the named inventor of Argentium Silver’s world-wide patented technology and therefore has the longest association with the business.  He brings practical experience as a silversmith, with a unique insight into silver production from both craft and industrial manufacturing perspectives. 


Peter trained and worked as a silversmith for twelve years and is a Freeman of the Worshipful Company of Goldsmiths.  During his apprenticeship he won a Gold Medal at The International Apprentice Competition, as well as several awards for craftsmanship.  His masterpiece to gain the Freedom of The Goldsmiths’ Company was a silver cross, which is now the Processional Cross used at Canterbury Cathedral.  Peter is also a Fellow of The Institute of Professional Goldsmiths.  Through his research into silver alloys, he has developed international links and working relationships with leading manufacturing companies.


Through his work as a lecturer in the School of Art & Design at Middlesex University (UK), he began his initial research into preventing firestain in sterling silver, which led to the development of Argentium Silver.  His further research at the University revealed that alongside firestain resistance, Argentium alloys display a range of other superior attributes including tarnish resistance, unique hardening properties, the ability to be fused to itself and other metals and being hypoallergenic.
