Heribert had a son named Stig who would take over the business as soon as he had finished his training as a goldsmith. In the late 1940s, Stig founded the studio named ‘Stigbert’, and the company started manufacturing jewelry. Thus began a new era in Swedish art jewelry using the Scandinavian design language. Typical patterns from this period were characterized by straight geometric shapes, shiny surfaces, and faceted rock crystals.
In 1962, after Stig Engelbert suddenly passed away, his sons Lars and Peter Engelbert took over the business. Though the two brothers were very young at the time, they had already obtained skilled training in goldsmithing in Germany and studied gemology in London.
The older brother Lars wanted to venture into the American market and went to New York in 1965, where he began working for the prestigious Mario Buccellati. One year later, younger brother Peter followed across the Atlantic, and together they opened their own office on Fifth Avenue in New York in 1966.
After five successful years of marketing Engelbert jewelry in the United States and Europe, the firm refocused its attention onto the domestic market and the two brothers returned home.
During the 1970s, Engelbert started making wedding and engagement jewelry using diamonds and other gemstones.
