Goldsmiths and Silversmiths in London, UK
Mayfair Goldsmiths, the trading name of G.J. Dennis Ltd, is a working goldsmiths and silversmiths workshop located in the heart of London’s West End. Trusted by generations of clients, we make and restore fine jewellery, trophies and heirlooms by hand, in-house and to the highest standard.
Whether you're commissioning a bespoke signet ring, restoring a family silver trophy, or updating an inherited piece, our goldsmithing and silversmithing services combine time-tested craftsmanship with modern tools. It's a traditional trade, and we’ve spent decades honing every step.
Our clients range from landed gentry to royals in the Middle East, American collectors, celebrities, and world sporting bodies. Much of our work comes by referral – tailors on Savile Row and prestigious families who’ve trusted us for decades.
Made in Mayfair,
Trusted Worldwide
We’ve been here for over 45 years, with over 100 years of combined expertise across our in-house team. Each piece is made or restored entirely in our Mayfair workshop by goldsmiths, silversmiths, polishers, engravers, mounters and valuers – all specialists in their craft.
From silverware for Michelin-star restaurants to family crests engraved on gold cufflinks, we work behind the scenes for people who value quality, discretion and longevity. We understand the meaning behind every piece and we treat each with the care and dedication it deserves.
What We Do
Bespoke commissions:
Signet rings, trophies, cufflinks, engagement rings, silverware, and objects made in gold, silver or platinum.
Restoration & repairs:
Invisible repairs, antique restorations, heirloom reworks, silver replating and more – all done on-site, never outsourced.
Upcycling:
We melt down, reshape and modernise old jewellery into something wearable again, without erasing its story.
CAD rendering:
We also offer CAD rendering, 3D printing and in-house casting, where appropriate. But the heart of our work is in the hand skills – traditional British craftsmanship with a modern edge.
