For almost 100 years, the Rosenstein Set, which is part of the Danish Crown Jewels, has lived a shadowy existence in the treasury display case under Rosenborg Castle.The set consists of a heavy pendant and a long chain – a so-called Gürtel – intended to be worn around the queen’s corseted waist. The chain was last worn by Queen Lovisa, who was the wife of Frederik VIII.But now the set is getting new life. Her Majesty the Queen and the Royal Collection have collaborated to transform part of the set into a tiara, respecting the history and the distinguished jeweler’s work that was displayed in the 1840s when designing the Rosenstein Set. By creating a new supplementary mounting frame for the set, it will now be possible to wear the largest diamonds of the Rosenstein Set in a tiara.With the creation of the new frame, The Queen and the Royal Collection are resuming the old tradition of adapting the crown jewels to the demands and needs of the times. This in many ways marks a new path for the Danish crown jewels, uniting the different traditions that have surrounded these four iconic jewelry sets – a path between revitalization and continuity.The new tiara is designed as a so-called Bandeau – a headband for mounting in the hair consisting of a single row of rose-cut diamonds. This simple shape continues the expression of the belt, where the diamonds are also mounted in a row.Since the historical settings from the 1840s are preserved in the new tiara, the back of the diamonds will remain closed, whereby the diamonds will not, as is normal in tiaras, be illuminated. As a result, they will appear less brilliant than if the case had been open settings.The frame on which the rose-cut diamonds in the new tiara are mounted was created by goldsmith Matias Hasbo Dinesen in consultation with the Queen and the Royal Collection.
