From Chicago, it was a circuitous journey to Aspen, Colorado. David attended American Jewelers Institute and received extensive training in the grading of diamond rough. He subsequently made regular trips to Cameroon, West Guinea, South Africa and the Democratic Republic of Congo (DRC) as a diamond rough buyer, bringing the diamond rough back to the US to be cut and sold in retail stores.
Because of David’s extensive jewelry experience, he was hired by a large company, with 24 retail stores, located on Grand Cayman BWI as the head of jewelry custom-jewelry design and manufacturing, and repair services. He held this position for three years before relocating his family to Aspen, Colorado. It is here he opened David Bull, Inc., which manufactures custom jewelry and high end men’s accessories.
