The Rose-cut Diamond Set is a part of the crown jewels.
The Rose-cut Diamond Set consists of a diamond belt as well as a large brooch – called a ‘corsage’ or breast ornament. The belt was intended to be sewn on the front of the dress as decoration with the large brooch, which can be divided into several smaller ones, at the top on the breast.
The current form of the set is, like the other crown jewel garnitures, from 1840, when Queen Caroline Amalie had them produced, but the majority of the set’s diamonds originate from Christian VI’s sister, Princess Charlotte Amalie. She, like her sister-in-law Queen Sophie Magdalene, wanted her jewels to go into a collection of Danish crown jewels.
The designation ‘rose-cut diamond’ is due to the old-fashioned way in which the historical diamonds are cut and which was used until the development of the brilliant-cut method in the latter half of the 1800s. The rose-cut method consists of many facets over the entire top side, preferably 24, which make the stone resemble a round rosebud, and a flat cut on the back. By contrast, the brilliant diamond has 33 cut facets on the top side and 24 on the lower side.
