Jack Spencer: Craftsmanship, Legacy and the Sheffield Story
The name Jack Spencer (Silversmith) Ltd will be familiar to many within the trade. In 2021, Jack’s son, John Spencer, visited the Sheffield Assay Office to explore our archives as part of a wider effort to document his father’s remarkable career—capturing not only the work, but the people, processes and philosophy behind the firm.
Jack Spencer built a reputation for creating modern, superbly crafted jewellery and silverware that remained accessible to the High Street customer. His work continues to be admired today, with many pieces now highly collectible.
Early Life and Training
Born in 1934 on Nethershire Lane in Sheffield, Jack was the son of John Henry Spencer, a steel strip hardener, and Winifred Gertrude Spencer. His creative talent emerged early; after passing the eleven-plus, he earned a scholarship to the Junior Art Department at Sheffield College of Art on Leopold Street. From the age of eleven, he began vocational training in silversmithing.
Jack later undertook an apprenticeship with Walker & Hall, briefly interrupted by two years of National Service in the RAF. It was during his time at Walker & Hall that he met fellow Sheffield-born designer David Mellor. This connection led to Jack working alongside Mellor at his innovative Park Lane workshop - an experience that would influence his design approach for years to come.
A Distinctive Design Philosophy
Following a short partnership with Keith Tyssen and periods teaching at Sheffield College of Art, Jack began developing his own jewellery range in the late 1960s. The collection proved immensely successful.
His ethos was clear: to create high-quality, handmade pieces at a price accessible to everyday customers. Many designs were crafted entirely by hand using just two widths and gauges of gold and silver wire—a testament to both ingenuity and restraint.
Production methods were equally distinctive. Designs were made in small batches, often ten at a time, with each piece completed start-to-finish by a single craftsman. This approach ensured consistency in design while allowing subtle variations—each piece bearing the individual touch of its maker.
Reflecting on this legacy, John Spencer once remarked that he had often been asked why he didn’t reproduce his father’s designs. His answer was simple: they were Jack’s creations. However, following growing demand, he eventually began revisiting the work, ensuring its continued appreciation.

Jack Spencer and The Assay Office Collection
The Sheffield Assay Office is proud to hold a number of pieces designed and made by Jack Spencer. Hearing John speak about these works—their origins, their makers, and the processes behind them—offered valuable insight into a truly distinctive period of British silversmithing.
Among the highlights are a pair of sterling silver cufflinks dating from 1993, where hallmarks are incorporated as a central design feature. These evolved from earlier designs in the 1970s and remain instantly recognisable.
Another standout is a pair of limited-edition goblets created to mark the bicentenary of the Sheffield Assay Office in 1973. Designed by Geoffrey Allsop and made by Jack Spencer, the first was a sterling silver goblet—number 1 of 200—presented at the Guardians’ Annual Meeting. A second version, crafted in 18ct gold, features the Crown town mark and reflects the same elegant design.
These pieces remain a particular favourite within the Office. Assay Master Ashley Carson notes:
“Jack was a very special customer of the Sheffield Assay Office. We are fortunate to hold several pieces in the collection by him and his designers.”
Recent Additions
More recently, the collection has been enriched by the addition of a unique three-piece sterling silver tea service, designed and made by Jack in 1963/64. The set includes a teapot with a rosewood handle and knop, alongside a milk jug and sugar bowl. Hallmarked across all pieces, this set is believed to be the only one ever made and was used by Jack and his wife in their home. It was generously donated by John Kelly.
Further notable items include a 9ct gold stick pin with three scrolls (1979) and a sterling silver gentleman’s ring (1974), both featuring distinctive hallmark elements that reflect Jack’s enduring design language.
