The stock consists mainly of Victorian and Edwardian pieces and includes the rare silver snuffbox, right, with a specially commissioned golf clubhouse lid by Garrard & Co, as well as an 18ct gold ring with two cut diamonds and further mine-cut diamonds to the twist.
The company have since announced they will be changing their name to Joseph Leonard Antiques and will now trade mainly in antique silver.
Anyone with information is asked to contact Avon and Somerset Police at the Bridgewater division on 0845 4567000 and quoting crime number 36166/11.
