The company, based in Knightsbridge, became a huge success and their costume jewelery was stocked at a number of major retailers and had a broad clientele which included Princess Diana and Boy George.
But while speaking of their co-creation in their book The Jewel Garden, Sarah opened up about the “humiliation” she, the trained jeweler, suffered alongside Monty.
“I would spend months working on a creation, drawing, refining, going backwards and forwards to the factory, checking samples, sorting out publicly,” she wrote.
“It was always a collaboration, although the factory owner who made up our jewelery only seems to listen to Montagu. I was invisible,” Sarah added.
