The development of jewelry and glass companies, which were established and prospered in North Bohemia at the turn of the 19th century, was interrupted by World War II.
In 1945, the seven main crystal factories and 18 small firms in and around Jablonec nad Nisou merged, forming the Preciosa company, which was officially established on April 10, 1948.
After the Velvet Revolution in 1989, in a less than transparent privatization process of the formerly state-owned enterprise,[5] Preciosa was gradually bought up the Communist era manager of the company.
