"Queen Sophia Charlotte was queen consort of the United Kingdom and wife to King George III of Britain. She is a direct descendant of the Sousa family, a black branch of the Portuguese Royal House. Her appearance was black, with full lips and distinct facial features. Artists of the 18th century were asked to tone down “extreme” features of their subjects, but Sir Allan Ramsay, an anti-slavery artist, always painted Queen Charlotte in her actual appearance."
This crown was created in 1856 by Russian Court Jewelers & made from silver & diamonds for Alexander II's wife, Maria Alexandrovna, who later presented it to her beloved daughter-in-law Dagmar-Minnie-Marie Feodorovna.
