Inside the Danish Crown Jewels

Beneath Rosenborg Castle in central Copenhagen, down a stone staircase and behind reinforced glass, sits one of Europe’s most fascinating royal collections. The Danish Crown Jewels are not locked away in a vault, seen only in old photographs. They come out several times a year, worn by Queen Mary at state banquets and New Year receptions, then go back into their cases in the castle’s Treasury for the rest of us to see. Few royal collections pull off that trick: treated as living jewellery and as museum pieces at once.

What makes a visit to the Treasury so absorbing is that the crown jewels are only half the story. Alongside them sit the Crown Regalia: the actual crowns, sceptre, orb and sword once used to make a Danish king. Understanding the difference between the two collections, and knowing what to look for in each, turns a walk through a handful of basement rooms into one of the richest short lessons in royal history anywhere in Scandinavia.

Crown Jewels versus Crown Regalia: the key distinction

It is an easy pair of terms to muddle, and the Treasury’s own layout does a good job of keeping them apart. The Crown Regalia are the instruments of monarchy itself: the crowns, sceptre, globus cruciger (an orb topped with a cross), sword of state and ampulla that were once central to a Danish coronation. They belong to the state, not to any individual, and today they appear only at a monarch’s lying in state, when the crown is placed on the coffin and the other pieces set at its foot.

The Crown Jewels are a different matter: privately commissioned jewellery, meant to be worn, that was designated as belonging to the Crown rather than passing down as personal inheritance. They are four sets, or garnitures, of gemstones, and they stay in active use. Queen Mary wears them for formal occasions within Denmark’s borders a handful of times a year. That may make this the only crown jewel collection in the world still worn for its original purpose and put on permanent public display.

The origins of the Crown Jewels

The story begins in 1746, when Queen Sophie Magdalene, widow of Christian VI, left instructions in her will that her jewellery should remain permanently attached to the Crown rather than being divided among heirs. It was a quietly radical decision. Whoever became queen consort in generations to come would have magnificent jewels to wear, whatever she brought to the marriage herself.

Later queens added to the collection, but its defining moment came almost a century later, between 1840 and 1842, when Queen Caroline Amalie had the German goldsmiths C. M. Weishaupt & Söhne of Hanau reset the existing stones into four coherent sets, in keeping with the grand fashions of the day. Queen Louise, wife of Frederik VIII, expanded the collection again around 1910, folding in older pieces and loose stones and commissioning the elegant three-drawer travelling case still used to transport the jewels today.

The four garnitures

Each of the four sets has its own character. The Emerald Set, created for Caroline Amalie in 1840, is generally considered the finest, its stones among the best emeralds anywhere in a European royal collection; it was also the only set originally created with a tiara. The Pearl-Ruby Set, completed in 1842, carries some of the oldest material in the whole collection, including a pearl necklace with pearls dating back to the late seventeenth century. The Brilliant-Cut Diamond Set brings together a necklace, corsage brooch and earrings in a more restrained, purely white palette. The Rose-Cut Diamond Set, worn as a corseted waist chain with a detachable central pendant, is the most unusual in form; Queen Mary has had elements of it reworked into a tiara for her own use since acceding as queen consort in 2024.

The Crown Regalia: crowns fit for a coronation

Where the jewels sparkle, the Regalia carry weight, literally and historically. The oldest crown, made for Christian IV by the Odense goldsmith Dirich Fyring between 1595 and 1596, weighs nearly three kilograms and is worked in gold, enamel and table-cut gemstones and pearls. Its enamelled figures spell out the virtues expected of a Renaissance king: fortitude, justice and charity, along with the pelican in her piety, a symbol of self-sacrifice, repeated three times around the band. It was worn at only two coronations, Christian IV’s own in 1596 and his son Frederick III’s in 1648, and survived being pawned more than once during lean years for the Danish treasury.

When Frederick III made the monarchy hereditary and absolute in 1660, he commissioned an entirely new closed crown for his son, deliberately different in shape from the older open crowns worn by Denmark’s elected kings. The Crown of Christian V, finished in 1670 and 1671, went on to be used at coronations through to 1840, the last occasion any Danish monarch was formally crowned. A separate, smaller Queen’s Crown completes the set of three, alongside the sceptre, orb, sword of state (the oldest single piece in the Treasury, dating to 1551) and the ampulla once used to hold the anointing oil.

Why Denmark stopped crowning its monarchs

Denmark’s 1849 constitution ended absolute rule and, with it, the ceremony of anointing and crowning a new monarch. Since then, Danish kings and queens have been proclaimed from the balcony of Christiansborg Palace rather than crowned in a cathedral, a simpler, more modern form of succession that many smaller European monarchies now share. That history is what makes the Regalia so poignant to see today: instruments built for a ceremony the country retired long ago, kept as a link to nearly three centuries of Danish coronations.

Visiting Rosenborg Castle’s Treasury

Rosenborg Castle sits beside the King’s Garden in central Copenhagen, and the Treasury occupies the castle’s basement rooms, reached by a stone staircase from the courtyard. Beyond the jewels and regalia, the castle keeps Christian IV’s own furnished apartments, including the bedchamber where he died in 1648, so visitors get a fuller sense of the building the collection has called home for centuries. Tickets can be bought online in advance for a modest saving over the door price, and a Royal Palace Pass covers several of Copenhagen’s royal sites for visitors planning more than one stop.

Because Rosenborg is a four-hundred-year-old Renaissance building, it was never designed with modern accessibility in mind: there is no lift, and visitors should expect stairs and narrow doorways throughout. Food and drink are not permitted inside, though a picnic area near the castle shop offers somewhere to break for lunch. Given the age of the building and seasonal changes to opening hours, it is worth checking the current times and ticket prices on the official website before travelling.

A treasury that still does its job

What lingers after a visit to Rosenborg is the sense of continuity behind the glitter of the display cases. Most European crown jewel collections have become entirely ceremonial, brought out for coronations that happen once in a generation, if at all. Denmark’s have kept working, taken from their cases for a state banquet or a royal wedding and returned again, generation after generation, to the same castle where the old crowns that inspired them have rested for hundreds of years. It is a rare kind of royal heirloom: history you can visit, and jewellery someone is still, quite genuinely, wearing.

Frequently asked questions

What is the difference between the Danish Crown Jewels and the Crown Regalia?

The Crown Jewels are four sets of wearable jewellery worn by the reigning queen consort at formal occasions, while the Crown Regalia are the historic crowns, sceptre, orb, sword and ampulla once used at Danish coronations and now reserved for a monarch’s lying in state.

Where are the Danish Crown Jewels kept?

Both the Crown Jewels and the Crown Regalia are kept in the Treasury of Rosenborg Castle in central Copenhagen, where they are on permanent public display when not in ceremonial use.

Who currently wears the Danish Crown Jewels?

Queen Mary has worn the Crown Jewels at formal state occasions within Denmark since becoming queen consort in 2024, continuing a tradition of use that stretches back to Queen Caroline Amalie in the 1840s.

How old is the oldest crown in the collection?

The Crown of Christian IV, the older of the two surviving Danish crowns, was made between 1595 and 1596 by the Odense goldsmith Dirich Fyring, making it well over four hundred years old.

Why does Denmark no longer hold coronations?

Denmark’s 1849 constitution ended absolute monarchy and, with it, the ceremony of anointing and crowning a new sovereign. Since then, Danish monarchs have been proclaimed rather than crowned, and the Crown Regalia have taken on a more symbolic, ceremonial role.

Can visitors see the Crown Jewels being worn?

Not in person during public visits; the jewels are displayed in the Treasury and worn separately by the queen at state functions, though photographs of these appearances are widely published afterwards.

What are the four sets of Danish Crown Jewels called?

They are generally known as the Emerald Set, the Pearl-Ruby Set, the Brilliant-Cut Diamond Set and the Rose-Cut Diamond Set, each created or reset in the nineteenth century from older royal jewellery.

Is Rosenborg Castle accessible for visitors with mobility needs?

Only in part. The castle has no lift and includes narrow staircases and doorways typical of a Renaissance-era building, so visitors with mobility needs should check current accessibility information before their visit.
