In the mid-1840s, one of Bolins and the world's most famous tiaras was crafted under the supervision of master craftsman Robert Schwan, known as the Vladimir Tiara. The tiara is now owned by the British royal family and was frequently worn by Queen Elizabeth II. It was commissioned in 1843 as a gift for the future Empress Maria Alexandrovna who later bequeathed it to her son Grand Duke Vladimir, whose wife Grand Duchess Maria Pavlovna often wore the beautiful tiara. Please examine the beautiful openwork backside of the brooch. The brooch is nearly as beautiful from the back as from the front.
