In the 1980s the British TV presenter, Monty Don, famous for his gardening programs, had a costume jewellery company. His wife Sarah was the jeweller. They sold in such places as Harrods. Due to inexperience and the Wall Street Crash of 1987, they went out of business and were penniless. Monty then managed to have a very successful career in television. Some of their pieces are marked on the back – Monty Don and are quite collectible and difficult to find.
