John Cadby Jewellers was first established in 1985 from very humble beginnings as a market trader, working the markets of Trowbridge, Chepstow, Frome, Tetbury & Devizes to name a few. In 1992 we moved to the Shires Centre and dedicated our time in creating our in house jewellery repair workshop, high-tech computer engraving machines and a watch repair facility. In 2011 we moved to our new location in White Hart Yard, to provide you with the best service possible.
