It's ten thousand miles from Sydney to the Amalienborg Palace in Copenhagen.
Crown Princess Mary of Denmark has certainly come a long way since she first met Crown Prince Frederik in the Slip Inn pub as the city staged the 2000 Olympics.
And the scale of her transformation will never be clearer than on Sunday. For, by the time evening falls, the princess will be Queen.
January 14 is when her 83-year-old mother-in-law Queen Margrethe steps down after 52 years on the throne, an abdication announced in a live television broadcast on New Year's Eve to the surprise of the Danish public.
Margrethe will replaced by her eldest son Frederik, with Mary as Queen Consort.
As Crown Princess, Mary already has all the fashions, stylists and accessories she could possibly need.
But this weekend, the Australian-born 'commoner' will be granted access to something else as well: a treasure chest of magnificent jewels to be worn by the queen. And only the queen!

The Danish Royal family is the only European royal family who can trace its lineage directly back to Gorm the Old and the first kings of their country.
Yet there hasn't been a coronation for more than 400 years and by the middle of the 18th century, there were no crown jewels.
That's when Queen Sophie Magdalen decided to rectify the situation, dictating in her will that her jewels must be passed down from queen to queen, bemoaning that:
'In this Royal House, there are so few jewels and not any crown jewels at all.'

Many of her original jewels were then redesigned in the 1840s by the German goldsmith C.M. Weisshaupt & Sons for Queen Caroline Amalie.
Probably the most important is the Crown Emerald Parure.
Created in 1840, it comprises of a diadem, a necklace, a brooch which can be taken apart and worn in several smaller pieces, and a pair of earrings - all set with brilliant diamonds and emeralds.
The largest emeralds were given to Queen Sophie Magdalene by her husband King Christian VI in 1723 to celebrate the birth of their first child, who became Frederick V.
It has frequently been worn by Queen Margrethe for State occasions, most particularly the New Year Reception.
This 1842 parure is made up of some of the oldest of the Danish jewels.
It includes a large pearl necklace, pearl, ruby and diamond earrings and a large pearl, ruby and diamond brooch which can be taken apart and worn in different ways.
Queen Margrethe sometimes wore the brooch attached to the necklace. There are also two small locks that can be linked together.

The large pearls in the necklace can possibly be traced back to Christian IV's daughter Leonora Christina Ulfeldt who is wearing a large pearl necklace in a 1647 portrait.
It is thought that when she was imprisoned for 22 years for supporting her husband, who was arrested for trying to poison the royal family, the pearls were passed to Queen Charlotte Amalie. She became queen in 1670.
According to Peter Kristiansen in his book Power, Splendour and Diamonds, the pearls could be Norwegian river pearls as Danish queens of the 1600s had exclusive rights to pearl fishing in Norway.
Again made in 1840 for Queen Caroline Amalie, this suite consists of a rose-cut diamond belt, which can be transformed into two necklaces, and a brooch which can be four smaller brooches.

Queen Caroline Amalie of Denmark
Queen Louise, mother of Queen Alexandra (wife and Queen Consort of Edward VII) and Empress Maria Feodorvna wore the belt on a number of occasions times.
This parure was created in 1840 by Weishaupt, for Queen Caroline to wear at the last Danish Coronation that year.

The sumptuous necklace is set with diamonds that had belonged to various Danish queens: Sophie Magdalene, Juliane Marie and Caroline Mathilde, as well as a princess: Charlotte Amalie.
According to the Royal Watcher blog, Queen Louise was able to take the necklace to London for the wedding of her grandson, the future George V.
The parure also includes diamond earrings and a spectacular floral corsage, the latter of which has yellow diamonds in the centre of several of the flowers.
It is made 'en tremblant' so the flowers move as the wearer walks.
