Sweden's Queen's Crown
One of the priceless artefacts on display in the Treasury at the Royal Palace of Stockholm is Sweden's Queen's Crown. This differs from the other crowns, being entirely dominated by large brilliants.
On 26 November 1751, Sweden's new king and queen – King Adolf Fredrik and Queen Lovisa Ulrika – were crowned at Stockholm Cathedral.
Forty-four very large brilliants had been given to – or placed at the disposal of – Lovisa Ulrika by the Swedish Riksdag on the occasion of her wedding in 1744. Prior to the coronation, these were incorporated into the new Queen's Crown.
The 1750s were a decade of political tension. In simple terms, the struggle related to "royal power" versus "people's power". The conflict between the king and the Riksdag came to a head during the 1755 Riksdag, with the monarch being the loser.
The queen, who had been born Princess of Prussia and was the sister of King Frederick the Great, could not accept the outcome of the 1755 Riksdag decision. For her, revolution was the only solution!
Mounting a revolution cost money, which was something Queen Lovisa Ulrika did not have at her disposal. Somehow, someone – or some people – close to the queen managed to replace the 44 large brilliants in the Queen's Crown with rock crystal.
The precious stones were smuggled out of the country and pawned with an antiques dealer in Hamburg. What the queen and her close circle obviously did not realise was that this man was a secret agent of the French government who bribed leading Swedish politicians.
The German antiques dealer understood where these jewels had come from, and immediately wrote to the French ambassador in Stockholm, informing him what had happened. The ambassador in turn notified the Swedish government, whereupon the attempted revolution was thwarted before it had even started.
This was a particularly humiliating episode for the royal family. The crown was restored to its original condition, and is now both a dazzling example of 18th century Swedish design and craftsmanship, and – in its own unique way – a work of political art.
