The rose-cut diamond tiara
A redesigned crown jewel from 2024

In collaboration with the Royal Danish Collection, HM Queen Mary has designed a new frame for mounting parts of the Rose-Cut Diamond Set.
Rarely used
The Rose-Cut Diamond Set was created in the 1840s and consists of a heavy pendant and a long chain. At the time, this type of chain, worn around a tightly corseted waist, was the height of fashion.
Until the time of the First World War, Danish queens wore the chain in the Rose-Cut Diamond Set in this way around the waist. After this time, however, both corsets and the related belts went out of fashion. As a result, the beautiful Rose-Cut Diamond Set had large gone out of use and has only been worn on a few, special occasions.
As far as we know, based on sources, neither Queen Alexandrine (1879–1952, Queen of Denmark from 1912 to 1947) or Queen Ingrid (1910–2000, Queen of Denmark from 1947 to 1972) ever wore the set.
During her reign, HM Queen Margrethe only wore the pendant, and only on two occasions. On both occasions, Queen Margrethe wore the pendant as a brooch.
The design of the new tiara
The new tiara is designed as so-called bandeau – a head band to be worn as a hair accessory – consisting of a single row of rose-cut diamonds. This simple design maintains the original expression of the belt, where the diamonds are also mounted in a row.
The tiara was created through the design of a new frame for mounting parts of the Rose-Cut Diamond Set. This enhances the wearability of the jewellery set and lets The Queen wear the largest diamonds as a tiara.
Naturally, the original mounts and settings have been preserved. Thus, the rose-cut diamonds can still be worn in their original form, as a belt, the way the set was designed in the 1840s, in case corsets ever come back into fashion.
