Berganza

Berganza works from 88-90 Hatton Garden in London, the street long associated with the city’s jewellery trade. The stock reaches further back than most period dealers, with ancient Roman and Greek pieces alongside Georgian, Victorian, Art Nouveau, Edwardian and Art Deco jewellery and rings from the 1940s and 1950s. Each item is dated and described on the website, so you can read the era and detail of a ring before you commit to it.

Beyond selling, the firm buys jewellery and runs an upgrade arrangement that puts the amount you paid for an earlier purchase towards a new one. Aftercare covers ring sizing, repairs, cleaning and insurance valuations, and orders ship with free fully insured delivery internationally, which is what makes the inventory practical for a buyer in Zurich. Berganza belongs to trade bodies including LAPADA, CINOA and the National Association of Jewellers.
