"Portrait of Margaret of Austria, Queen of Spain and Portugal (1584-1611)", Juan Pantoja de la Cruz, circa 1607

"the queen is depicted as immutable and inscrutable, somehow hidden behind her extraordinary dress and the enormous ruff collar that isolates and highlights her illuminated visage. She wears the spectacular ‘joyel rico’ which is one of the most famous jewels in history. With origins from the 16th century it consists of the el estanque table-cut diamond and from it hangs the la peregrina pearl given to mary i of england (1516-1558) by phillip ii as an engagement gift but returned to the spanish crown on her death [. . ] the present work appears to be a bust-length workshop variant of the artist's three-quarter length portrait in the museo del prado, madrid (inv. No. P01032). ". Date: circa 1607. Dimensions: height: 79 cm (31.1 in); width: 67 cm (26.3 in). Medium: oil. Collection: Unidentified location. Workshop of Juan Pantoja de la Cruz - Margaret of Austria, Queen of Spain
