One of the last companies in the United Kingdom still making silverware by hand, Theo Fennell also brings its creativity and brilliance to masterfully crafted jewelry.
Born in 1951 into a military family, founder Theo Fennell grew up all over the world and later studied at Eton College, York College and the Byam Shaw School of Art. He began as an apprentice and designer at silversmiths Edward Barnard before opening his studio across the street. In 1997, Fennell moved into a purpose-built building on Fulham Road in London where his studio operates today.
All of the company’s necklaces, bracelets, earrings, rings, brooches and cufflinks are handmade with an unparalleled level of detail and attention. Its breadth of jewelry includes the King Henry VIII brooch honoring the powerful monarch with an 18kt white gold and enamel portrait set with diamonds, sapphires, emeralds and rubies. The Colosseum ring — a collaboration with micro-sculptor Willard Wigan MBE — is an 18kt yellow gold miniature recreation of the Rome landmark with a 2mm high gladiator standing center stage.
The company also creates bespoke pieces, corporate gifts and trophies including commissions for the Italian Grand Prix, the Monaco Grand Prix, the Dubai Championship Stakes, the PGA European Tour, the European Film Awards and the Nordoff Robbins O2 Silver Clef Awards.
To support the next generation of artisans, Fennell started Gilded Youth, an initiative that sponsors prizes, awards and programs for both secondary and college students. Fennell is a member of the Goldsmiths’ Company and an honorary fellow of the University of the Arts London.
