W.A. Bolin was established in 1791 in St. Petersburg, Russia, and has been family-owned ever since, earning Bolin the title of the world's oldest jewellery family in the business today. During the firm's tenure in Russia they were court jewellers to five Russian tsars, alongside Fabergé, with whom they at one time planned a merger. Due to the Russian Revolution, however, Bolin moved to Stockholm, Sweden, where they have since been established and served three Swedish royal courts. Bolin remains of the most important jewellers in Sweden.
